立式锅炉以结构简单、价格低廉、占地面积小的优势受到中小型企业青睐。立式锅炉排烟温度高(测试冲天管出口烟温高达280℃左右),排烟热损失所占比例过大,热效率远低于同容量卧式锅炉。因此,立式锅炉科学配置烟气余热利用装置以提高热效率。1锅炉尾部烟气余热吸收装置的研制TSG G0002-2010《锅炉节能技术监督管理规程》中明确规定“额定蒸发量小于1t/h的蒸汽锅炉排烟设计温度不高于230℃”。据调查,目前立式
Vertical boiler with simple structure, low cost, small footprint advantage favored by small and medium enterprises. Vertical boiler exhaust gas temperature is high (testing the export pipe smoke temperature as high as 280 ℃), exhaust heat loss proportion is too large, the thermal efficiency is much lower than the horizontal boiler with the same capacity. Therefore, the vertical boiler scientific configuration flue gas waste heat utilization device to improve thermal efficiency. 1 Development of boiler tail flue gas waste heat absorption device TSG G0002-2010 “Boiler Energy-saving Technology Supervision and Management Regulations” clearly states that “the rated evaporation of less than 1t / h steam boiler exhaust design temperature is not higher than 230 ℃ ”. According to the survey, the current vertical
