高品位热能利用汽轮机选型及节能效应
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.
