摘要

介绍了超临界600MW机组中压缸起动的主要步骤及暖缸、切缸等关键技术

总结了中压缸起动的优点。中压缸起动虽然系统较复杂

起动操作有一定难度

但却是一种安全、经济、快速、灵活的起动方式。建议采用闷缸自暖、辅汽预暖或邻炉再热蒸汽预暖与主蒸汽预暖相结合的暖缸措施

进一步加快起动速度

减少起动消耗。

Abstract

The main steps of starting the supercritical 600 MW unit up through IP cylinder

as well as warming the cylinder up

switching the cylinder over

and other key technologies have been presented

and the advantages of starting the unit up through IP cylinder being summarized.Although the said start-up mode is somewhat complex

and the starting operation is slightly more difficult

but it is a safe

economical

rapid

and flexible way to start the unit up.It is recommented to adopt some measures for warming the cylinder up

such as the main steam prewarming combined with self-warming with the cylinder being tightly covered

prewarming with auxiliary steam or reheating steam from neighboring furnace

to further accelerate the start-up

reducing consumption in start-up.
