To decrease the power load of the coal-fired power plant, the surplus heat is stored in the thermal storage system to be used later. The equivalent round-trip efficiency of the thermal energy storage system is up to 85.17%, which is achieved by the appropriate match between the heat sources and the thermal storage media.
We proposed a novel efficient operation scheme for a thermal power plant''s air-cooling system based on peak shaving, in order to cope with high ambient temperature in summer. We introduced an absorption-generation equipment with water/lithium working pairs into the air cooled condenser (ACC) to reconstruct the …
