燃气轮机变工况运行时中压汽包水位波动原因及分析
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
