In this method of combustion, coal fuel is burned in a bed of hot inert, or incombustible, particles suspended by an upward flow of combustion air that is injected from the bottom of the combustor to keep the bed in a floating or “fluidized” state. The scrubbing action of the bed material on the coal fuels enhances the combustion process by stripping away the CO2 and solids residue (char) that normally forms around the coal fuels particles. This process allows oxygen to reach the combustible material more readily and increases the rate and efficiency of the combustion process. One advantage of mixing in the fluidized bed is that it allows a more compact design than in conventional water tube 10 ton steam horizontal wood pellet biomass boiler designs. Natural gas or oil fuel can also be used as a start-up fuel to preheat the coal fired steam fluidized bed or as an auxiliary fuel when additional heat is required. Beside, the effective mixing of the bed makes fluidized bed boilers well-suited to burn solid refuse, wood waste, waste coals, and other non standard fuels. The fluidized bed combustion process provides a means for efficiently mixing fuel with air for combustion. When coal fuel is introduced to the bed, it is quickly heated above its ignition temperature, ignites, and becomes part of the burning mass. The flow of air and fuel to the dense bed is controlled so that the desired amount of heat is released to the furnace section on a continuous basis.

Wood fired steam 10 ton steam horizontal wood pellet biomass boiler in Thailand is widely applied in industrial fields because of its eco-friendly and economical. Thailand is an emerging economy and is considered a newly industrialised country. And its warmly developing industries need large scale machines such as industrial steam boilers. Biomass fuel is a kind of renewable resource, and Thailand has rich bioful resource. So, in Thailand, biomass fired steam boiler like wood fired steam boiler, rice husk fired steam boiler, palm shell fired steam boiler, etc is welcomed.
Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of 38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original 10 ton steam horizontal wood pellet biomass boiler equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.
