联合循环机组不设启动锅炉的可行性分析及应用实践

Combined cycle unit without start-up boiler possibility analysis and application

针对燃气-蒸汽联合循环机组轴系的不同配置特点,论述了机组不配置启动锅炉的适用性及可行性。结合某工程实践,在无启动锅炉、无外来蒸汽情况下,通过余热锅炉所产生的蒸汽作为启动蒸汽,研究了机组辅汽系统设计及其实际应用状况。

The applicability and possibility of not provide start-up boiler was discussed based on gas-steam combined cycle unit shaft configuration.Combined with project practice,in the situation of without start-up boiler or other external steam,the design and application of unit auxiliary steam system was studied.
