%X 构造了煤制氢新工艺系统,对新工艺气化过程热效应进行了分析,结果表明降低压力和提高温度在热力学上有利于气化反应的进行。根据热力学分析结果,对系统中气化炉热效应和整个系统的热效率进行了模拟计算,得出:该工艺可以提高单位原料煤的产气量,煤气中有效成分含量高,有效的利用了煤炭资源,系统的热效率可以达到90.65%。 Hydrogen from coal is a main means of obtaining hydrogen,and it has strategetic value to study it. The author has constituted a new technology system of hydrogen,and analysed reaction heat on gasification process. The results have indicated that the decrease of pressure and increase of temperature are favorable to the gasification. According to thermodynamics analysis results,the reaction heat of gasifying furnace and the thermal efficiency of overall system have been simulatively calculated,and results are that gas quantity of the unit raw coal is enhanced and the effective component content is higher than before in gas. Coal resources are used effectively. The system thermal efficiency has been up to 90.65%
