Feasibility Study on FW-Pump Steam Drive Turbine Exhaust Heating Technology

The technical reliability and economic benefits of energy saving technology of FW-pump steam drive turbine exhaust steam heating technology was analyzed. The results show that the technology has an obvious energy-saving effect and significant economic returns. Relative to the conventional winter heating system, using heating-net circulating backwater as a small turbine condenser cooling medium, to recover turbine exhaust heat recovery and improve the water return temperature in order to reduce heating steam consumption, has a very good application prospects, and can achieve the dual purpose of increasing thermal efficiency and energy saving.
