Abstract
This report describes a new method for heat recovery in entrained gasifier process. The method adopts a wet coal supply system of high dense coal water slurry (CWS) at the stage of coal feed, then through fluidized bed tube type heat exchanger, CWS is heated rapidly by raw gas that has high sensible heat. This process converts a wet type coal feed into a dry type one by super heated steam and makes low specific oxygen demand. The driving power for oxygen generation plant is also obtained from recovered steam which is produced by making use of sensible heat of the raw gas. These methods will produce a high integrated thermal efficiency.
