Japan Coal Energy Center｜Japan Coal Energy Center. Integrated coal Gasification Combined Cycle (IGCC) is new technology with lots of attention in recent years from the view point of reduction of various environmental impacts. In this system, ash content of coal after gasification process is made into the form of slag instead of coal ash.

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 municipal lighting, and heating ...

In a slagging combustion system, some of ash/slag generated through the combustion of solid fuels is molten and adheres to tube surfaces or the refractory wall during operation. A submodel for predicting molten slag droplet deposition in the slagging combustion systems has been developed. The maximum spread diameter and excess rebound energy have been defined and applied to establish the ...
