摘要(Abstract)：

针对目前锅炉补给水处理系统因原水温度低,而利用高品质蒸汽加热耗费能源的现象,提出利用发电厂循环冷却水的余热,加热锅炉补给水处理系统的原水。分析了4种原水加热器系统运行方案,目的在于回收部分废弃的热量。通过技术和经济性比较,给出采用热水加热器和蒸汽加热器配合使用方案,达到节能减排,同时满足各种运行工况需求,综合经济性能指标较高。
Due to low temperature of raw water in boiler feedwater treatment system,high-quality steam is used for heating that consumes too much energy. Therefore,the paper proposes to use waste heat from power plant circulating cooling water to heat raw water of boiler feedwater treatment system. The paper analyzes four operation schemes for raw water heater system,aiming to recycle part of the waste heat. Through technical and economic comparison,the paper presents a scheme of combing hot water heater with steam heater to save energy,reduce emissions as well as meet requirements of different operating conditions. The scheme is characterized by its higher integrated index of economical efficiency and performance.
