350MW超临界机组膜式水冷壁壁温计算
Numerical Calculation of the Temperature Field of Membrane Water-wall of 350 MW Supercritical Boiler
摘要
Abstract
In view of the temperature characteristics of semi circumference heated membrane water-walls in a 350 MW supercritical pressure boiler,a calculation program was built to obtain spiral membrane water-wall temperature distribution under different furnace loads.The results showed that:the uneven distribution of furnace heat load led to uneven heat of water-walls;temperature on the facing flame side of water-walls fluctuated within a narrow range,which was the same as the fin.The distribution of temperature on the facing flame side was low in the middle and higher on other sides.With the increase of height of furnace,temperature of waterwall rose and there was a certain fluctuation.The highest temperature appeared on the facing flame side of the fin,and the lowest temperature appeared on the inner wall of water-wall bus bar when BMCR load was 75%.关键词
