| Abstract: | The exergie analysis model of underground coal gasification (UCG) process was established. The mass and energy conversion of special UCG system was studied and evaluated. The evaluation of UCG process in Liuzhuang mine shows that 1) the general exergie efficiency of the UCG process is about 85.18% ;2) the outer-supply exergie efficiency is 65.66%; and 3) the irreversible exergie loss is 14.82%. Compared with the ground surface gasification, the exergie efficiency of underground gasifier is higher than that of blast furnace and ground surface gasifier but lower than that of coke oven. The exergie loss mainly comes from the irreversible losses of both combustion and heat transfer. |
