燃用高水分、高挥发分、低热值的褐煤锅炉,普遍存在着着火、燃烧不稳定和低负荷稳燃的问题.采用煤粉浓缩器是解决上述问题的有效措施。本文就煤粉浓缩器的研制,从其工作原理、模化方法进行了分析和介绍,并针对具体对象的要求进行了模化试验,其结果可为燃用高水分褐煤电厂采用煤粉浓缩器的设计,提供依据. Combustion of lignite boilers with high moisture content, high volatility and low calorific value has widespread problems of ignition, unstable combustion and steady combustion at low load.The adoption of pulverized coal concentrator is an effective measure to solve the above problems. In this paper, the research and development of pulverized coal concentrator has been analyzed and introduced from its working principle and molding method, and the mold test has been carried out according to the requirements of specific objects. The results can be that the pulverized coal concentrator The design provides the basis.
