Title:
噴流層石炭ガス化炉及び石炭ガス化方法
Document Type and Number:
Japanese Patent JP3578494
Kind Code:
B2
Abstract:
According to the apparatus and method, combustible gas having a stable composition can be formed even if the load is charged. Burners are provided in the upper and the lower regions of an entrained bed coal gasification reactor. The temperature of the product gas is kept low in the upper region and high in the lower region. The volumes of the upper and lower regions are changed to meet the load so that the rate of heat loss becomes constant even if the load changes. Since the rate of heat loss can be kept constant and consequently variation of the composition of the product gas can be suppressed small, the efficiency of the coal gasification electric power generating system can be kept constant.
