Analysis of Combined Heat and Power Supply Performance Based on Humid Air Two Shaft Gas Turbine
In order to study the combined heat and power supply capacity of humid air cycle combined with heat exchangers based on two shaft gas turbine,the modular thermodynamic model of two shaft gas turbine was estab-lished based on a twin shaft gas turbine in the facility.And using the model,a heat and power combined analysis platform is built.The thermodynamic performance of the base turbine was studied and the influence of heat sup-ply,heat exchanger bypass ratio and fuel supply on cycle performance was analyzed.Result shows the thermoelec-tric ratio can vary from 0 to 3.54 with an drop in electric efficiency of 6.72％and an increase in overall efficiency of 18.4％.On the control strategy the heat exchanger bypass ratio,water flow rate of economizer and fuel flow rate is to be raised together in order to keep the gas temperature and hot water temperature constant without influenc-ing the electricity generation capacity.
