The combustion part of the wood fired biomass boiler adopts light chain grate with two side air intake. Six independent air chambers are arranged under the grate, and air regulating mechanisms are arranged on both sides of the air chamber. The air is blown into the two side air channels at the bottom of the base by the blower, and enters the independent air chamber through the air regulating mechanism. The upper furnace wall of the wood fired steam boilers is assembled from the factory, and the lower furnace wall and the front and rear arches are composed of refractory clay bricks, silicate fibers and thermal insulation materials. The fuel from the self-feeding coal scuttle enters the furnace through the coal gate for combustion, and the burnt cinder falls into the slag hopper under the operation of the grate and is discharged by the screw slag extractor.
The boiler is equipped with an electric control console, which is equipped with a boiler thermal parameter display instrument, a drum, an induced draft fan opening indicator, and a remote control button of the electric actuator. The boiler feed water adopts automatic feed water device and is equipped with over temperature alarm device. This series of boiler products are respectively provided with a manhole device for the upper and lower drum, one for the front and rear of the upper drum, and one for the lower drum. Two sections of the left and right collecting boxes are provided with one hand hole each. It is convenient for boiler maintenance, and also provides great convenience for boiler cleaning after cutting off the furnace.
Wood fired steam boilers grate adopts new large coal leakage furnace row, convenient and reliable operation. The grate plate greatly improves the reliability of the boiler operation, and basically realizes the hot grate plate is not strained and not easy to damage. The coal leakage of biomass fired boiler is less than that of sheet grate, and the fuel can be saved by about 2%, and the ventilation condition is good, and it has a certain self-cleaning capacity. This boiler absorbs the advantages of quick installation boiler, compact structure, boiler room for single-layer layout, convenient installation, short cycle, low cost, simple operation.
SZL double drum boiler is used in food factory, chemical plant, oil field, textile factory, pharmaceutical factory, building materials factory, dairy factory, edible fungus factory, clothing factory, paper factory, winery, commercial building, power plant (auxiliary), residential area and other industries. Auxiliary boiler accessories are complete, equipped with induced draft fan, blower, water pump, computer control cabinet, automatic softening water treatment, steam water pump, hot water circulation pump, economizer, dust collector, chimney flue, chain grate, feeder, slag machine, speed regulating machine, etc.
This series of steam boiler adopts reasonable furnace structure and outlet temperature, the best ratio of convection heating, S-type flue gas circulation, initial separation of dust inertia, reduce the original dust concentration. The boiler is equipped with ash blower and convenient ash removal device. Precise design of smoke and wind resistance, reasonable smoke airflow velocity and low resistance, make each heat close to the best, fully ensure the output of the boiler. The wood fired steam boilers has a large grate length to width ratio, which increases the residence time of biomass particles in the furnace, and the biomass particles are burned more cleanly.
