Introduction to Coal Gasification / IGCC technology:
IGCC stands for “Integrated
Gasification combined cycle”. The preliminary conversion into
a gaseous fuel originated is named as SynGas / Synthesis Gas. Synthetic gas is an
intermediate source for generation of hydrogen, ammonia, methanol, & other
synthetic hydrocarbon fuels. For electricity generation, synthetic gas is not only used as fuel of internal
combustion engines due to its combustible nature, but also plays an important
role in keeping the plant eco- friendly.
During Coal storage at a large scale, for
harnessing coal's energy more cleanly and efficiently, a number of different
ways attempted in order to motivate environmental concerns. Among them, the
technology comes out to be most successful is ‘coal gasification’, where instead of burning the fossil fuel, it is
chemically transformed into synthetic natural gas or syngas.
What is the Need:
Till now, the main
objective of Conventional Thermal Power Plant was to increase the efficiency by
means of increased temperature and pressure in the steam, which in turn generate
an efficient power outcome. But today theneed is to get more efficient power
production along with keeping the outside eco friendly. With the technical
advancement in working methodology, the upgraded thermal power plants are now
capable to generate power using Coal Gasifiers in purpose to increase efficiency of the plant.
Advantages of using the Coal Gasifiers:
·
Clean Energy Conversion:From an economic and energy
security perspective, coal gasification is proved themost successfulprocess to
dealt with clean energy conversion, since instead of opening the intermediate
poisonous gases up to exploitation, coal gasification helps to access these
resources cleanly.
·
Environment Friendly:Addressing the atmospheric
problems resulting from burning coal and getting least affected by these
poisonous gases is one of the top priority objectives of coal gasification.
This Enviironment friendly feature of coal gasification is also thekey to achieve near-zero emissions from gasification-based
power generation.
·
Enhanced Power Generation& Reduced Resource
Consumption:In coal based thermal power
plants, synthetic gas collected during the coal
gasification is used as fuel of
internal combustion engines due to its combustible nature, which in turn not
only participate in enhancing power generation but also reduces the resource
consumption.
·
Easy
Installation and Maintenance: Coal Gasifiers, whichare the main source to
carry out coal gasification are installed in conjunction with coal bunkers. As
far as their fixing and maintenance is concerned, these coal gasifiers are very simple to install and to maintain for the
long term.
