摘要: 针对给水泵汽轮机排汽采暖供热节能技术进行技术可靠性和经济收益分析,研究表明该技术节能效果明显、经济收益显著。对比常规热网系统,用热网循环回水作为小机凝汽器冷却介质,回收排汽余热以提升回水水温,减少采暖蒸汽用量的方案,具有较好应用前景,可实现提高机组热效率和节约能源的双重目的。Abstract: 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.
