供热机组中压缸排汽参数的确定方法
A new method for determining exhaust parameters of medium-pressure cylinder of heating units
摘要
Abstract
The heat user, heat network and thermal-system heater were taken as a whole, the heat load needed by the heat users and water-side parameters of thermal-system heater were calculated based on the thermal-system heater, and according to the change of outdoor ambient temperature during the heating period, and the exhaust parameters of medium-pressure cylinder of heating units were determined after calculating the steam-side parameters of thermal-system heater according to the heat transfer theory and combined with the performance of turbine and the combined performance of cogeneration system. The accurate calculation of medium-pressure exhaust parameters of heating units was done through establishing its mathematical model and iterative calculation. The results show that the extraction parameters for heating, which meets the different heat needs during the whole heating period, are calculated accurately in this method, and can be used as a guide to regulate the operation of power plant. The problem of how to determine the parameters of the second cold source in the off-design power calculation of heating units is solved and the conditions for the heating units off-design calculating is provided. The reliable basis for the depth research of cogeneration field can be provided using the accurate quantitative data.关键词
