摘要
建立了煤气、热和电多联产系统采暖季流程,在Aspen Plus平台上对该流程进行了模拟,获得了系统的状态参数和过程参数,运用系统能量综合利用系数、日经济收益、联合循环热效率和热电联产子系统能量综合利用系数来评价系统性能,分析了系统关键操作变量对系统性能系数的影响。研究表明,燃气循环、蒸汽循环和联合循环的热效率分别为33.55%,29.76%,38.48%;系统能量综合利用系数和热电联产子系统能量综合利用系数分别为75.94%,53.31%。
The model for gas, heat and power eogeneration system in winter was established. State parameters and procedure parameters of the system were obtained by process simulation on platform of Aspen Plus. Performance of the system was evaluated by energy integrated utilization coefficient of the system, profit, thermal efficiency of combined cycle and energy integrated utilization coefficient of heat- power cogeneration subsystem. Influences of key operation variables on these coefficients were analyzed. The results show that the thermal effieiencies of gas cycle, vapor cycle and combined cycle are 33.55%, 29. 76% and 38. 48% respectively. The energy integrated utilization coefficient of the system and the energy integrated utilization coefficient of heat--power cogeneration subsystem are 75.94 % and 53.31% respectively.
