垃圾焚烧在减容化,无害化、资源化处理城市垃圾方面的综合效果显著。循环流化床锅炉由于燃烧效率高,适应性广,并且容易满足环境保护的要求,在电力与热电行业应用越来越广泛。文章结合垃圾焚烧炉的运行特点,针对垃圾焚烧机理和循环流化床的运行原理,讨论了DCS 系统的设计与应用。 Abstract: Rubbish burned has a prominence result at reduce pollution, no-harmful and so on.CFBB have a wider application in the electric power industry because of its high combustibility and demanded of the environment protection. This article arised the featrue of CFBB, especially the principle of the CFBB in order to discuss the design of the DCS system.
