影响1025t/h控制循环锅炉再热器喷水因素的试验研究

Study on Reheater Water Injection Factors of 1025t/h Forced Circulating Boiler

国内许多运行的 1 0 2 5t/h控制循环锅炉主要性能参数均能达到设计要求 ,低负荷稳燃性能好 ,启停速度快 ,调峰能力强。但是锅炉普遍存在再热器喷水量偏大的问题 ,影响了机组运行经济性。通过某台 1 0 2 5t/h控制循环锅炉再热器喷水的试验 ,分析研究影响再热器喷水量的因素 ,为同类型机组的设计优化、运行和改造提供参考。

or: Most of 1025t/h forced circulating boiler performance can reach the design demands perfectly, with the better steady combusting at low load, starting up and getting off rapidly and the strong capacity of the load change. One of the main problems is that the reheater water injection amount is too large, and this affects the economical performance of the unit greatly. Base on a series of the reheater water injection site experiments, this paper studies the affecting reheater water injection factors and gives some of the recommends for the design optimization, unit operation and retrofitting.
