为了在火电厂煤粉炉中使用干排渣系统 ,国电富通科技发展有限公司设计了回转式水冷冷渣器。设计时 ,计算了冷却高温灰、渣所需的冷却水量、最小传热面积、辐射换热量和导热换热量 ,并推导出相应的计算公式。最后 ,讨论了该冷渣器的传热计算方法及结构等有关问题 ,从而明确了设计回转式水冷冷渣器的思路 In order to use the dry slag discharge system in coal-fired power plants, GD Futong Technology Development Co., Ltd. designed a rotary water-cooled slag cooler. During the design, the cooling water quantity, minimum heat transfer area, radiant heat transfer and heat transfer heat exchange capacity of cooling high temperature ash and slag were calculated and the corresponding formulas were derived. Finally, the heat transfer calculation method and structure of the slag cooler are discussed, and the idea of ​​designing the rotary water-cooled slag cooler is clarified
