Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a circulating fluidized bed boiler capable of incinerating domestic garbage. Background technique [0002] With the development of the economy and the improvement of people's living standards, municipal solid waste has increased significantly. In the past ten years, urban waste has been increasing at a rate of 7% per year, and the per capita daily waste production is about 1 to 1.5 kilograms. Therefore, the complete treatment of solid waste, and making it resourceful, reduced and harmless has become an urgent problem to be solved. At present, there are many ways to deal with waste, and the commonly used treatment methods are: landfill, composting and incineration. The landfill method occupies a large area, takes a long time to process, destroys the natural landscape, and cannot realize resource recovery and capacity reduction. The composting method has a long ...
