控制循环锅炉蒸汽加热设计与应用

Design and application of steam heating for control circulation boiler

国内引进控制循环锅炉时,未设计邻炉底部蒸汽加热。如何在控制循环锅炉增加临炉蒸汽加热装置,是摆在当前的现实课题。本文通过在汽包内部增加加热蒸汽管道,实现机组启动前炉水加热,提高启动阶段安全性和经济性。

When the control circulation boiler is introduced into China,the steam heating at the bottom of the boiler is not designed.How to control the circulation boiler to add the steam heating device is a realistic task at present.In this paper,the steam pipe is added in the drum to heat the boiler water before the start-up of the unit,and the safety and economy are improved.
