循环流化床锅炉改造为链条炉的炉拱设计与配风调整

Designing of Boiler Arch and Adjusting of Air Distribution in Transforming Circulating Fluidized Bed Boiler to Chain-boiler

根据生产需要将循环流化床锅炉改造为链条炉.新设计的链条锅炉改善了煤的引燃,提高了燃烧区的燃烧强度,结合推迟配风方法,在实际应用中掺烧70%无烟煤,取得了较好的经济效益.

On the basis of the need of productive adjusted load,the circulating fluidized bed boiler was transformed into chain-boiler.The arch of the chain-boiler was designed to improve the coal ignition and the boiler combustion.At the same time of retarding,air distribution should be taken to make the distribution more much reasonable.Good economic benefit was acquired in the practical application,by mining 70 % anchracite combustion.
