Abstract:

The model for gas, heat and power cogeneration 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 [KG*4]that the [KG*4]thermal [KG*4]efficiencies of [KG*4]gas [KG*4]cycle, vapor [KG*4]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.
