摘要

提出了一种简便的节能诊断方法

并利用机组性能试验数据和汽轮机结构参数进行了分析计算。对某典型的330MW机组汽轮机通流部分、回热系统、给水泵汽轮机(小机)、减温水、轴封系统、凝汽器、抽汽压损、汽水损失以及全部运行参数进行热力性能诊断

给出了能损分布图。诊断表明

各项因素热耗偏差总和为448.25kJ/(kW.h)

与试验值448.43kJ.(kW.h)基本吻合。

Abstract

A simple and convenient diagnosis method of energy-saving has been put forward

and the analysis and calculation being carried out by using the performance test data and the turbine's structural data.The operation performance diagnosis of flow passage in steam turbine

as well as of heat regeneration system

feed-water pump

small steam turbine

desuperheating water

shaft seal system

condenser

pressure loss of the extracted steam

loss of steam and water

and all parameters in operation has been carried out for a typical 330 MW unit

and the energy loss distribution diagram being given.The diagnosis shows that the total deviation of heat consumption for all factors is 448.25 kJ/kWh

tallying well with the designed value and tested value.
