摘要

三菱公司M701F燃气蒸汽联合循环机组配套的余热锅炉中压汽包容量小

在燃气轮机变工况运行时

中压汽包水位易产生较大的波动。依据旁路阀的控制逻辑

结合机组调试运行中的实际情况

分析了在燃气轮机变工况运行时中压汽包水位波动的原因

并提出了解决措施。

Abstract

The capacity of IP drum for a heat recovery boiler equiped in coordination with M70E gas and steam combined cycle made by Mitsubishi Corporation is small

the water-level in IP drum is easily to produce comparatively large fluctuation when the gas turbine runs in off-design condition. Based on control logic of the by-pass valve

and combined with practical situation in debugging operation of the unit

the causes resulting in water-level fluctuation in IP drum when the gas turbine runs in off-design condition have been analysed

and solving measures being put forward.
