Coal gasification is a process which is still in its development phase, this process involved conversion of coal to gas by anaerobic combustion in a closed chamber. The bye product of this burning is a mixture of hydrogen and carbon monoxide also known as Syngas.
Syngas has a wide range of applications ranging from electricity production to sponge iron production and fertilizer production. In a typical UCG (Underground Coal Gasification Plant) the process takes place by controlled burning of coal and about 350m ofgas can be produces from one Metric Tonne of coal. Such a process leads to lower cost of energy and overcomes hazards of open cast mining operations. Other advantages of Coal gasification are listed below :-
- No significant change in the Landscape
- No surface disposal of slag and ash
- Environment friendly , reduced greenhouse gases
- Produces ammonia, syngas, water vapours, phenols etc
Coal gasifiers requires large storage of bulk materials such as coal which is used as the raw material for the process, typically the stockyard stores 100,000 - 200,000 Metric Tonnes of coal for gas production. The coal is often stored in open piles at the surface which can pose threats to the environment and the plant functionality. Coal storage shed is the solution to issues arising from such bulk storage yards. These sheds can cover large spans of up to 150 meter allowing tandem plant operations even for automatic plants with stacker and reclaimers.
- Coal storage shed protects the coal from rainfall which can deplete the coal quality leading to reduced Gross calorific value and lower plant efficiency.
- Coal storage sheds reduces the air pollution caused to the nearing areas, this leads to better health of inhabitants in the vicinity of the coal gasification plant.
- Coal storage shed protects coal from spontaneous burning, which leads to Carbon dioxide pollution and loss of coal.
