Title:
コンバインドサイクルプラントの制御装置及びコンバインドサイクルプラントの停止方法
Document Type and Number:
Japanese Patent JP6882945
Kind Code:
B2
Abstract:
To improve an operation rate by shortening a time for stopping a combined cycle plant, in a control device of the combined cycle plant and a stop method of the combined cycle plant.SOLUTION: A control device of a combined cycle plant comprises: a gas turbine 11 having a compressor 21, a combustor 22 and a turbine 23; a waste heat collection boiler 12 for generating steam by the waste heat of an exhaust gas from the gas turbine 11; and a steam turbine 13 which is driven by the steam generated by the waste heat collection boiler 12. The control device controls an output of the gas turbine 11 so that a lowering rate of an exhaust gas temperature reaches a cooling rate by the steam which maintains a clearance between a stationary part and a rotating part of the steam turbine 13 to a preset allowable clearance or larger.SELECTED DRAWING: Figure 1
