Biomass boiler is a horizontal three – trip water – fire tube boiler. Boiler fuel is agricultural and forestry waste as raw materials, after grinding, mixing, extrusion, drying and other processes, into a variety of molding (such as block, granular, etc.), can be directly burned as a new clean fuel biomass fuel. Biomass chain grate boilers does not require uniform feeding, according to good fuel can choose the way of human feeding and mechanical feeding, using biomass fuel, environmental protection clean, in line with environmental protection requirements.
According to the fuel characteristics, this series of biomass boiler can adopt manual or mechanical feeding mode. The ignition speed can be controlled by adjusting the secondary air volume. Long wood strips (L≤2M) can be burned without breaking. Uniform feeding is not required. Combustion equipment for chain grate. Left and right sides of the chamber of a stove or furnace water wall as the radiation heating surface, flanked by convection chamber of a stove or furnace heating surface, drum inside decorate threaded pipe convection heating surface, wall insulation layer adopts the new type concrete insulation pouring dao made process, boiler host lateral for three-dimensional shape plate shell.
Biomass chain grate boilers body in the overall structure of the upper pot, water wall tube and the collection box symmetrical arrangement of the form. The pot barrel is welded by the barrel body and the front and rear tubesheet. This series of biomass fired boilers adopt new scientific research achievements, such as arch tube plate, threaded smoke pipe, secondary air, chain grate, etc., which solve the problems of boiler shell lower drum, tube plate crack, low thermal efficiency, insufficient output and so on.
When the biomass boiler is burned, the fuel enters the furnace through the coal gate and burns on the chain grate grate. The flue gas generated along the bottom of the boiler barrel enters the two wings convection tube through the exit smoke window on the figure 8 wall, enters the threaded pipe through the front smoke box, and enters the economizer. After sufficient heat transfer, the flue gas passes through the induced draft fan into the dust collector for dust removal and is discharged into the atmosphere through the chimney.
Biomass chain grate boilers structure design advanced and reasonable, stable and smooth operation, safe use, long life.
