In general, the industrial boilers fall into two categories: watertube boiler and firetube boiler. The water tube boilers are very common in industrial application and utilities. The watertube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam.

Types of water tube boilers

• SZS oil & gas D type boiler
• SZL chain grate water tube boiler
• Circulating fluidized bed boiler 
• Waste Heat recovery boiler

 

• SZS oil gas D type water tube boiler

For most industries that need not very large quantity of 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.

• Circulating 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 6-400 t/h.

• SZL coal and biomass water tube boiler

The ZBG's chain grate boiler is designed to adapt to the ideal alternative heating fuel for your application. 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.

 

• Waste heat recovery water tube boiler

ZBG offers years of experience utilizing waste gases from various industrial processes can be recovered to reduce energy consumption. Waste heat recovery boiler for sale is mainly used to generate steam and power by utilizing waste gases in refinery, petrochemical incinerator gases, thermal oxidizer gases, nitric acid process gases, fume incinerator gases, coking, FCC, cement kilns.
