Applications of Pre-engineered Buildings

Ever since the technology of pre-engineered buildings was introduced, its merits have been appreciated. Over the passage of time, more and more advances have come in making these structures extremely versatile and useful. The speed and ease of construction, mobility, timeliness of project completion and remarkable cost-efficiency that is brought about in PEB projects is universally acknowledged. Let’s have a look at some of their most common applications:-

     ·  Factories: Most factories have some basic structural requirements including parameters of safety, durability and effective utilization of space, with fairly minimal design customization needed. As a result, steel buildings can prove sturdy effective as factory structures.

      · Warehouses or Distribution centres: The same holds true for storage spaces, distribution areas, warehouses and logistics centres. A basic structural steel framework with ready, finished roofing and cladding parts is fully capable of fulfilling their requirements.

     

   · Industrial sheds & Hangars: Metal Buildings with ready to assemble-ridges, bays and designated areas for different functions prove quite useful for constructing industrial sheds. In fact, the large span structures like aircraft hangers can be commissioned in remarkably short times.

    · Indoor and outdoor stadium with canopy: By adding elements like colour & type variations in the roofing and cladding and other exterior finishes. PEB’s can develop into rather attractive –looking structures that have now found wide acceptance as sports facilities such as stadiums.

Types of Tensile Membrane Structures

The term tensile membrane structures describes the category of buildings in which the load bearing capacity is achieved through tension stress in majority of the components, such as cables, technical fabrics or foils. A membrane structure is most often used as a roof, as they can attractively and efficiently span large distances.

Flexible Design Aesthetics, Outstanding Translucency, Excellent Durability, Lightweight Nature and Low maintenance are some of the great advantages and functional benefits of tensile membrane structures.

Types of Tensile Membrane structures - 

1) Saddle Roof

The saddle is a hyperbolic paraboloid, which means that the membrane structure is characterized by two high peaks and to low points; in other words, the saddle can be conceptualized as a warped rectangular grid.

2) Mast Supported

Tent-like in appearance, mast supported structures typically have one or sometimes several peaks that are supported by either interior or perimeter masts. These structures can also be supported by adjacent buildings. The peaks of a mast supported structure are determined by the design and how the fabric is attached. These structures are primarily suitable for long span roofs.

3) Arch Supported Roofs

Curved compression members are used as the main supporting elements and cross arches are used for lateral stability. In a plane arch, large differences between the thrust lines and the main geometry will produce large bending moments that in turn produce large changes in shape and high stress in the arch chord section. One method to significantly reduce these effects is to tie or restrain points along the arch chord to reduce the initial large deformations of the chord.

About Hindustan Alcox Limited  

As a leading Membrane structure manufacturer, Hindustan Alcox Limited specializes in creating complex structural systems with sophisticated design practices. Our fabric structure which include tensile membrane structure, requires a prior understanding of shape and form, the behaviour of the materials used and the forces acting on it. All these parameters are studied by our designers to conceptualise and engineer the final product.

Popular Facts about Dome Structures

A dome is typically an element of architecture that resembles the upper half of sphere. Dome structures are curved – they have no angles and no corners – and they enclose an enormous amount of space with the minimum of materials as they don’t require interior supports. Despite their slenderness, dome structures are some of the strongest and stiffest structures in existence today. There is no denying that the domes are amongst the strongest architectural forms to have been developed in the construction industry. Listed below are some important facts about dome structures that have revived their demand in the modern construction industry:-

·  Bulk storage domes are extremely efficient and cost effective structures as they are lighter in weight as compared to other building styles. In addition they can be constructed with significantly lesser material and provide a much longer life.

· The absence of any corners, angles and flat surfaces make these structures highly resistant to high pressure winds and hurricanes. This is because the winds are able to pass smoothly over their circular shape while creating minimal turbulence due to excessive air pressure. This makes dome structures aerodynamically stable.

· Most modern buildings having dome shaped structures use the geodesic domes which are specially engineered for efficient utilization of space besides making the construction highly economical.

· Given the inverted circular design of the dome shaped structures, the dissipation of energy is also carried out in a highly efficient manner. This means that the various sections of structures can be rapidly heated and cooled in an even manner.

Types of Coal Storage Sheds

During the storage of coal many challenges arise such as spontaneous combustion of coal, loss of GCV (gross calorific value) and fugitive dust emissions. Due to rise of these kinds of problems there is a significant monetary and environmental loss. Coal storage sheds are considered as the perfect solution to overcome the challenges. With the help of coal storage sheds, these problems can be eliminated easily without damaging the environment. There are 2 types of Coal storage sheds-

1. COAL STORAGE - BARREL VAULT SHED

In this case, coal storage will be formed by the conventional rail mounted stacker cum reclaimer machines will be covered within the shed. The length and span of the shed could be adopted depending on the quantity of the storage required. In case of future expansion the length of the shed can be increased and same stacker reclaimer can be used for higher volumes. 

2. COAL STORAGE - DOME SHED

In this type of structure, the shape of the shed will be in the semi hemispherical form. There will be a concrete wall up to a certain height from the ground level and the structure will be erected above this wall. The dome structure of various sizes could be adopted depending on the quantity of storage required. A circular stacker and scraper type reclaimer could be used for reclaiming the coal. With this type of shed, coal will protected from wind and rain and hence the problems associated with these will be avoided. This kind of storage shed can accommodate higher quantity of coal in a smaller area as the height of storage could be increased.

Impact of Open Coal Stockpiles

Majority of the coal stockpiles inside the Indian power plant are open type built with various kinds of stackers and reclaimers. This type of open storage poses both environmental and functional loss. There are several problems being faced with the present type of open stockpile system.

Functionality loss-

1) Combustion of Coal – Spontaneous coal combustion in open storage is one of the major concerns in the thermal power plant. The spontaneous combustion of coal in the open stockpile results in the degradation of the coal and causes changes in the physical and chemical properties of the coal.

2) Loss of GCV – Coal loses the gross calorific value when stored in the open. This increases the amount of energy required per unit

.

3) Loss of Coal – 2.4% of coal goes to waste due to erosion by wind and percolation of the coal during rainfall.

Environmental loss-

1) Fugitive dust nuisance from the stockpile due to the wind – Due to the fugitive dust emission from the stockpile, dust particles will be carried by wind and causes pollution. This would pollute the plant area and could cause damage to the other utilities like cooling towers, switch yard etc in the power plant.

2) Ground Water Contamination – Percolation of the coal particles with the rain water contaminates the ground water.

In view of the problems faced in the open type stockpile, there are many alternative methods of storing the coal but Coal Storage Sheds are the best possible solution to address the issues listed above. Coal Storage sheds is highly specialized and comes with following advantages. The cost of structure is 30-40% lower as compared to other conventional structures. This structure installation does not impact the productivity of the plant. Since this structure uses circular sections that coal dust accumulation is kept minimal on the members.

Read More - Commonly used Building construction types

Commonly used Building construction types

There are different types of construction which are used for constructing building, homes, sheds, and such. When it comes to designing a structure, the construction type is chosen based upon a number of things such as Purpose of the structure, Size of the structure, Load bearing constraints, Environmental factors, Cost of materials and Speed of construction.

Here are the most commonly used building construction types-

1. Pre-engineered Construction

Pre-engineeredbuildings (PEB) are those building in which excess steel is avoided by tapering the sections. They are mostly constructed in a quicker way as compared to any other construction type. The key advantage of Pre-engineered buildings is low installation time. All the parts are ready to be bolted and screwed together.

Fast construction, Engineered to handle all the loads, Easy to design and manufacture are some major advantages of pre-engineered buildings which make them different from others.

2.  Steel frame Construction

Steel frame construction is used primarily in large span steel structures. These specialised steel structures are built from steel column and steel trusses to support floors and roofs. Large span steelstructures and High rise buildings are commonly built using this method, as it’s easy to transport materials up using cranes and the components are quickly bolted or welded together.

Steel is flexible, due to which it helps in earthquake prone areas or in areas of high wind. Steel can flex quite a bit without taking on permanent deformation, making it a great material for constructing tall buildings, steel bridges etc.

3. Concrete Frame construction

Concrete frame construction uses reinforced concrete columns, concrete beams, and concrete slabs to built the support structure. This construction type is often used in high-rise buildings and elevated roadways.

In building construction most all components are casted on site, thus construction time is not fast due to the curing time of the components. Concrete frame construction does not hold well to earthquakes, although it does weather wind effect and weather well, over time.

Challenges in Pet-coke Storage

Petcoke is a bye product / undesirable product of oil refining cracking process. Petcoke is often used because of its high-calorific value as well as lower handling cost per unit of Heat Content.

In comparison to coal, petcoke is categorized as a material with low volatile,  lower ash content, high fixed carbon content and high sulphur content. It is also used as a complementary fuel in cement industries.

Challenges in Petcoke Storage:-  

·    During Petcoke storage, temperature of the exhaust gas increases if petcoke is introduced with raw material resulting into increased gas volume and increased specific heat consumption. In that situation, the benefits should be worked out considering reduction in Kiln production and increased fuel consumption.

·     Petcoke has some toxic contents like vanadium, nickel etc, which go along with dust. Hence, plants which dispose the return dust have to ensure that the concentration of these compounds do not exceed the limits defined by the environmental laws.

·  Due to the establishment of large outdoor petcoke storage, many concerns about possible public health consequences by petcoke emission have been raised. Moreover during its bulk storage, many problems like spontaneous combustion, fugitive emission etc can occur at any stage of transportation, storage and handling.

These are some major challenges which are faced during the storage of petcoke. Petcoke storage sheds are the ultimate solution of these problems. These sheds are designed in such a way that these problems of spontaneous combustion, fugitive emission can be controlled without any loss to the stockpiles quality.

Role of Gypsum storage in FGD/Flue gas desulphurization unit

Gypsum is a mineral found in sedimentary rock formations in a crystalline form known as calcium sulphate dehydrate CuSo₄.2H₂O. Gypsum Storage at large scale is needed since it is one of the prime raw material in the cement industry and in power plants for FGD plants. In purpose to improve cement’s inherit qualities, performance and efficiency, a composite gypsum storage solution need to be followed systematically:

Gypsum Handling 

Gypsum handling includes bunkering of gypsum, along with its stacking and reclaiming in a very cautious way. A gypsum handling system adds flexibility and automation to a processing facility helping to ensure that gypsum moves efficiently from one stop to the next and even to a storage and transport. As an aggregate, gypsum can be a difficult material to handle, requiring a system that is robust and able to with stand a rigorous workload. Gypsum is usually stored under well constructed sheds ensuring its storage without deterioration and without exposure  to moisture and heat, and away from the direct sun.

For environmentally friendly gypsum storage and production of a best outcome in cement industry, today almost all out-performing cement plants use to store gypsum stockpiles under a strong, durable, eco-friendly and solution-rich gypsum storage sheds and gypsum storage. 

Role of gypsum storage system in FGD/ Flue gas desulphurization Unit:

The resources like coal, petcoke contain a significant amount of sulphur into them. In many large scale power plants and cement plant (where the raw material is Coal, petcoke etc), the problems arises from boiler or furnace where large volumes of So₂ accumulation not only deteriorates air quality of environment but also highly corrosive for handling equipments like stackers, fans etc.

In order to extract So₂ from flue gas, the mechanism of extraction employed is known as FGD or Flue Gas Desulphurization. In Flue Gas Desulphurization, the chemical Techniques are used to exclude sulphur di-oxide (So₂) in exhausted flue gasses from the Furnace/boiler. Some of the Chemical techniques used for FGD are ‘Wet Scrubing’, ‘Dry Scrubing’, ‘SNOX FGD’ etc.

The output from flue gas desulphurization is synthetic gypsum, which is carried out under FGDSHEDS. For cement manufacturing, this FGD storage product or synthetic gypsum is supplied in crushed form for further fine grinding with cement clinker and has many other commercial applications in cement industry, bricks manufacturing etc.

Read More - Gasification of Coal

Gasification of Coal

Gasification of coal is a high temperature process which is developed to produce a fuel gas with minimal of liquid and solids. Coal Gasification take place in a gasifier, generally in a high temperature vessel where oxygen and steam directly contracted with the coal causing a series of chemical reactions to occur that convert the feed to syngas and ash. Syngas is composed primarily of the colourless highly flammable gases carbon monoxide (CO) and Hydrogen (H2).  Coal Gasification is considered as a partial oxidation process.

Applications of Coal Gasification:-

¨ One of the most abundant energy sources

¨ Can be used to produce ultra-clean fuel

¨ Leading source of electricity today

¨ Chemical Production (Methanol, ammonia, acetic acid etc)

¨ Hydrogen made from coal or other solid fuels can be used to refine oil, or to make products such as ammonia and fertilizer (urea).

¨ By product of burning (ash or slag) can be used for concrete and roadways

Gasification is attractive for its simple but brutal operation. Higher efficiency, cleaner output and more control over products can only help the economics. As other sensor technologies are introduced gasification could be a leading refining technique for a wide range of raw materials from trash to cultivated biomass and on to coal. Gasification might not be elegant – but the process enjoys the leading spot for going to commercial scale in today’s market for synthetic fuel process. Particularly in clean generation of electricity from coal, gasification may make an increasingly important part of the world’s energy and industrial markets.
