High-Temperature combustion of Pyrrolyzed Char Containing Calcium Sulfide

摘要

In response to the United States Department of Energy's (U.S.DOE) national research program called "Combustion 2000," the High Performance Power System (HIPPS) scheme was developed by the Foster Wheeler Development Corporation (FWDC). The Hipps involved pyrolyzing a high sulfur-containing coal in the presence of limestone sorbent to capture sulfur as CaS and then combusting the resulting char containing spent and unspent sorbent and coal-ash with the fuel gas (mostly CO, H_2, and CH_4) in a high-temperature furnace called HITAF to drive the steam cycle.
