锅筒排污水炉内切向喷雾强化燃烧

Tangential Spray Intensified Combustion in a Boiler Furnace with Continuous Blowdown

采用锅炉排污水降压汽化作为蒸汽喷雾介质，在炉内燃烧空间形成切圆旋流，强化炉内燃烧，改善炉内气流动力分布状态。经过ＵＧ－３５／３９型锅炉的试验和应用考核，飞灰含碳量和炉渣含碳量分别下降２５．８％和１１．６％，飞灰量和烟气排放浓度均大幅度下降，烟气排放的ＳＯｘ含量可得到有效控制。

With the pressure reduction evaporation of boiler blowdown water serving as a steam spray working medium a tangential circle swirl flow can be formed in the combustion space of the boiler,resulting in an intensified combustion and the improvement of aerodynamic distribution in the furnace.The test and use verification on a UG 35/39 boiler have shown that the fly ash carbon content and boiler slag carbon content are lowered by 25.8% and 11.6% respectively.In addition,a considerable reduction of the fly ash quantity and gas emission concentration is also attained with a simultaneous effective control of SO x content in the gas emissions.
