【Abstract】 Combined cool, heat and power is an effective way to realize energy cascade utilization, which is an important development direction that has received widespread attention. From the extraction condensing steam turbine of a 350 MW supercritical unit in a severe cold areas, under the condition of ensuring flexible heating, some steam was extracted with appropriate parameters as the driving heat source of the lithium-bromide double effect absorption refrigeration system. A model of the combined cool, heat and power system(CCHP) is established and is computed to analyze the coal consumption for heating, the heat supply capacity of the heat network, and the utilization rate of primary energy of the system. The results show that the combined cool, heat and power system in severe cold area is feasible and effective, which can provide references for the future development of the combined cool, heat and power system.更多还原
