Water tube type boilers and fire tube boiler or smoke tube boilers are the main two types of industrial boilers that widely used for industries. For fire tube boilers, wns type oil gas fuel boilers are the most widely used. For water tube boiler, there are many types, such as D type water tube boiler, fluidized bed type water tube boiler, traveling grate type water tube boiler. They are all different with each other. Most of water tube boilers are packaged boiler, which is convenient to be installed. Fuel equipment can be freely chosen, the combustion chamber can freely design with more complete combustion. Large heat transfer area, better thermal efficiency, saving fuel costs.
Oil gas water tube boiler
For most industries that need not very large quantity if steam or hot water, oil gas fired water tube boiler is the best choice because of packaged structure and highly automatic control. The furnace of water tube boiler is be placed outside the cylinder so various volume of the furnace can meet the requirements of combustion and increased evaporation. The heat transfer performance and safety performance is significantly improved. The capacity of D type water tube boiler is 6-35 t/h, which can meet almost all need of industries.
Fluidized bed type water tube boiler
Compared with oil gas water tube boiler, fluidized bed type water tube boiler has a large capacity and is used in large industries or power plants. Fluidized bed combustion technology is widely applied in large scale water tube boilers. With this combustion technology, the fuel stay in furnace for a longer time to be burnt thoroughly, which can get a higher efficiency. In many industries, circulating fluidized bed combustion boilers are widely used to supply adequate steam or hot water. The capacity of cfb water tube boiler is 10-280 t/h.
Chain grate water tube boiler
As a boiler that can burn both coal and biomass fuel, traveling grate type water tube boiler is an ideal equipment for industries. Biomass fuel can save a lot for industry and it is more environmental friendly. The capacity of it is 4-30 t/h, , which can meet the condition of stop or start at any time.
