摘要

The regenerative cycle system based on absorption heat pump heats feed water through steam driving absorption heat pump by absorbing the low temperature waste heat of circulating cooling water, the system can reduce the circulating water temperature and low pressure heater extraction, and further to improve the thermal efficiency of unit. By studying on supercritical 600MW unit according to equivalent enthalpy drop method, the influence of steam turbine efficiency and unit economical efficiency were analyzed. The analyses show that it is feasible to use the regenerator cycle system based on absorption heat pump in thermodynamic system of thermal power plant.
