| 摘 要： | 压缩空气和水蒸气是水煤浆锅炉气力式雾化的两种常用介质.对两者的技术及经济性进行了比较研究.通过对炉内颗粒水分蒸发速率的Spalding模型和燃烧阶段的对比分析表明,电厂采用压缩空气做雾化介质更具有较好的技术经济性.对每单位容量(t/h)的水煤浆喷嘴,采用压缩空气代替水蒸气雾化,每小时可节约相当于8～10kg的标准煤.

| Abstract: | Gas-assist nozzle is widely used in CWS(Coal-Water Slurry) boiler,the atomization medium being compressed air or water vapor.A techno/economic analysis is made.By means of a Spalding modeling of the liquid evaporation,and process analysis in the combustion stage of the droplets,it is shown that in the case of power plant CWS boiler,compressed air is more technically economic than water vapor for the use of atomization medium.For CWS atomization,8-10 kg/h standard coal can be saved per t/h of nozzle capacity... |
