Integrated coal gasification combined cycle (IGCC) technology is being promoted to make better use of energy resources, and an entrained‐flow gasifier is a key item of equipment in the process due to its high gasification efficiency, smooth discharge of molten ash, etc. The temperature and heating rate under entrained‐flow gasification conditions are very high, and these two parameters can influence...
Gasification of a char has so far been mainly studied at low temperatures and low heating rates with a TGA (thermogravimetric analyzer). Studies on gasification of a char in CO 2 at elevated temperatures and high heating rates are necessary to develop IGCC technology. With a unique fluidized bed, the effect of pyrolysis time on char reactivity was investigated. It was found that a longer pyrolysis...
