The high efficiency cycle includes carried-heat partial gasilication, compressed air heating in a fiuidized bed immersed air heater followed by a combustor and the heat recovery of gas turbine exhaust used as the combustion air for the differential-velocity atmospheric circulating fluidized bed (DFBC). Superheat steam is raised in the DFBC boiler. The comparison of results identifies the causes of performance difference between eight cases. Features of the cycle ensure a high coal conversion efficiency within current state of the art.展开更多
