Abstract

To simultaneously enhance waste heat recovery, peak shaving and valley filling capacity of existing air-cooled coal-fired cogeneration system, an improved complementary energy supply method is proposed based on absorption heat pump (AHP) and compressed air energy storage (CAES). The improved cogeneration system CPHP-CAES forms a CAES-assisted coal-fired cogeneration mode during charging process and a coal-fired cogeneration assisted CAES mode during discharging process. Energy, exergy, economic and environmental (4E) evaluations are carried out to reveal advantages. Compared with original coal-fired cogeneration system adopting AHP for waste heat recovery (CPHP), maximum output power and heating load of CPHP-CAES are increased by 85.98 MW and 87.39 MW, and minimum output power is decreased by 94.83 MW at an extraction flow rate of 80 kg/s. Meanwhile, the waste heat recovery rates during charging and discharging phases are improved by 4.45 % and 9.41 %, and overall thermal efficiency is enhanced by 1.78 %. The maximum saving coal consumption rate is 3.48 g/kWh. The dynamic payback period (DPP) is reduced by 0.11 years, multiple of invested capital (MOIC) and net present value (NPV) are increased by 0.02 and 81.04 M$. The annual CO2 emissions are reduced by 36,228.53 tons.
