At present, there are a huge number of coal-fired boilers in China, and their slag has a high carbon content. The original combustion method cannot recycle it, resulting in a large amount of fuel waste. However, high-speed circulating fluidized bed hot water boilers can effectively burn low calorific value fuels and mixed fuels of slag and ordinary coal, which can reuse the previously discarded slag. At the same time, there are abundant low calorific value lignite resources in Xinjiang and Inner Mongolia, which also provide users with a large amount of low-priced fuel. Moreover, the slag of circulating fluidized bed boilers has good low-temperature burning permeability and is suitable for use as an admixture in building materials, achieving the goal of comprehensive utilization.

The market for large circulating fluidized bed hot water boilers is positioned for urban centralized heating, with an annual demand of approximately 5000MW. At present, the main boiler products used for centralized heating are traditional chain furnaces. With the introduction of national energy conservation, pollution control and environmental protection policies, traditional chain grate boilers will gradually be replaced by circulating fluidized bed boilers.

This type of CFB hot water boiler is a coal-fired circulating fluidized bed boiler with a single drum horizontal arrangement, forced circulation, balanced ventilation, and a π - shaped layout. It mainly consists of a membrane water-cooled furnace chamber, a central cylinder offset high-efficiency adiabatic cyclone separator, a self balancing return valve, and a tail convection flue. The tail vertical shaft flue is equipped with a light tube economizer and primary and secondary air preheaters. The boiler adopts a fixed method combining front suspension and rear support, which is suitable for indoor and semi outdoor layout.
