一、概述中参数或次高压背压式汽轮机,其复速级后、压力级前,一般都设有或可以装设不调节抽汽口,这个不调节抽气口,本来是为工矿企业具有不同参数的热用户而考虑的,可是,由于通常热负荷参数部在汽轮机的背压排汽参数以下,一般使用背压排汽就能满足供热的需要,不调节抽气就被搁置不用了。人们对不调节抽汽注意甚少,随着时间的推移,汽轮机上的这一装置遂成为了被遗忘的角落,以至于在工艺生产中,当需要有高于汽轮机背压排汽参数的热负荷时,人们住往囿于习惯,宁可将新鲜蒸汽经减温减压供给
First, an overview of the parameters or sub-high-pressure back pressure turbine, its speed level, the pressure level before the general are equipped or can be installed without adjusting the exhaust port, this does not adjust the exhaust port, originally for industrial and mining enterprises have different However, due to the usual thermal load parameter in the steam turbine back pressure exhaust parameters below the general use of the back pressure exhaust to meet the needs of heating, without adjusting the exhaust was put aside. Little attention was paid to not adjusting the steam extraction, and over time the unit on the steam turbine became a forgotten corner, so that in process production when it is necessary to have a heat above the steam turbine back-pressure exhaust parameter Load, people live in the habit of habit, preferring to supply fresh steam by reducing the temperature and decompression
