CFD simulations of influence of steam in gasification agent on parameters of UCG process

TL;DR: In this article, the issue of amount of steam in reacting system was analyzed in given paper, which indicated a possibility of conduct of stable gasification process (with predictable characteristic of gas) and demonstrated the possibility of deterioration of conditions in real reactors as a result of applying of too high amounts of steam.

General model of coal devolatilization

TL;DR: In this paper, a general model for coal devolatilization is presented, which considers the evolution of gas, tar, char and guest molecules, and combines two previously developed models, a Functional Group (FG) model and a DevolATilization-Vaporization-Crosslinking (DVC) model.
