摘要

某热电厂将高品质蒸汽直接通过减温减压器

降低参数后用以提供低温低压工业用汽。对其进行改造

提出用背压式汽轮发电机来代替减温减压器的改造方案

可以有效利用高品位热能进行发电

然后用背压机排汽供工业用汽

达到节能降耗的目的

并据此详细阐述背压机的选型过程。

Abstract

A thermal power plant used a PRDH（pressure reducing desuperheater） to get low pressure low temperature steam from high quantity steam directly for industrial use. This method is a great waste of energy. An improvement is carried out to deal this situation. A backpressure turbine is suggested to substitute the PRDH

so that more power could be got from this steam conversion. This improvement could increase thermal efficiency and conserve energy. A detailed computation process is discussed.
