垃圾焚烧汽轮发电机组低压加热器疏水改造

Drainage Improvement of Low Pressure Heater of Waste Incineration Turbine Generator Unit

本文对某垃圾焚烧发电项目汽轮发电机组(两炉一机)低压加热器疏水提出改造方案,增加设置低加疏水泵,对比分析汽轮机改造前后热平衡,分析其经济性。对垃圾焚烧汽轮发电机组节能改造、热能高效利用提供参考思路。

In this paper,a transformation scheme is proposed for the drainage of the low-pressure heater of the steam turbine generator unit(two boilers and one unit)of a garbage incineration power generation project.The low-pressure heater drainage pump is added.The thermal balance before and after the transformation of the steam turbine is compared and analyzed,and its economy is analyzed.It provides reference ideas for energy saving transformation of waste incineration steam turbine generator unit and efficient utilization of heat energy.
