试论锅炉减温水对汽轮机组热经济性的影响

Discussion of the Influence of Boiler Attemperation Water on Turbine Units Thermo-economy

近些年,我国工业行业的发展越来越迅猛,很多地区的工业发展也融入了现代化的设备和体系。其中汽轮机组热力系统的出现为锅炉减温水的运行提供了一定的保障。一般情况下喷水减温对机组热经济性影响较大,如果将热器减温水取自给水泵中间抽头,其电煤耗电量就会有所上升,可见锅炉减温水对汽轮机组热经济会有着一定的影响。本文笔者将会针对1000MW汽轮机组热经济性进行简单的分析,并对减温水对某机组热经济性的影响等内容进行具体的阐述。

In recentyears, China＇s industry develops more and more rapidly and many regional industrial development also applies the modern equipment and system, of which, the emergence of turbine units thermodynamic system provides a certain security for the operation of boiler attemperation water. Generally, the spray desuperheating has a larger effect on the turbine units thermo-economy, if take center tapping for heater attemperation water self-supporting, its electricity-coal consumption of electricity will have certain increase, so it is can be seen that boiler attemperation water has a certain impact on turbine units thermo-economy. In this paper, the author will take simple analysis of the 1000MW turbine units thermo-economy, and take concrete exposition of the influence of attemperation water on certain turbine unit thermo-economy etc. Content.
