国产2093t/h亚临界压力控制循环锅炉因锅炉给水与减温水压差较小,无法满足锅炉升降负荷时正常的喷水减温用量,造成后屏过热器管壁温度超限。本文结合电厂改造实际,探讨在给水管道上加装憋压阀确保差压建立,保证减温水正常投入和预防锅炉过热器超温,供电力同行参考。
國產2093t/h亞臨界壓力控製循環鍋爐因鍋爐給水與減溫水壓差較小,無法滿足鍋爐升降負荷時正常的噴水減溫用量,造成後屏過熱器管壁溫度超限。本文結閤電廠改造實際,探討在給水管道上加裝憋壓閥確保差壓建立,保證減溫水正常投入和預防鍋爐過熱器超溫,供電力同行參攷。
국산2093t/h아림계압력공제순배과로인과로급수여감온수압차교소,무법만족과로승강부하시정상적분수감온용량,조성후병과열기관벽온도초한。본문결합전엄개조실제,탐토재급수관도상가장별압벌학보차압건립,보증감온수정상투입화예방과로과열기초온,공전력동행삼고。
Due to the small pressure difference between the feedwater and the spary water,domestic 2093t/h sub-critical pressure controlled circulation boiler can not meet the normal amount of spray water requirement when it is increasing and decreasing load,which results in overtemperature in the pipe wall of rear platen superheater.In this paper,in the consideration of the practice of power plant reconstruction,it is discussed to install pressure-differential valve on water supply pipe to ensure the establishment of...
