Simulation and economic evaluation of coal gasification

The coal gasification process in this study does not use coal-water slurry feed or a SETS cycle for power generation. The coal feed stream and the HRSG were simulated using the properties of coal and steam pressures presented in the guidelines respectively. Some of the capital cost was calculated using the equipment cost estimations.

Fire and Explosion Prevention in Coal Pulverizing Systems

Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent. All these factors make the coal/ air mix- ture easier to ignite and, once ignited, more likely to detonate and cause an explosion.

Coal gasification

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before
