The 2 ton biomass boiler adopts the layer combustion method, and the fuel can be fully burned on the grate, which greatly improves the combustion efficiency of the boiler and reduces the emission of exhaust gas. DZL series chain grate boiler is a horizontal three-pass water-fire tube boiler with a boiler capacity ranging from 2 to 10 ton/hr. A tobacco pipe is arranged in the boiler drum, and the water-cooled wall of the furnace is installed on the left and right sides of the furnace. The light chain grate is equipped with a blower and an induced draft fan for mechanical ventilation, and a scraper-type slag discharge machine is arranged to realize automatic slag discharge. The front and rear arches of the furnace adopt a new energy-saving technology furnace arch. The fuel falls from the coal hopper to the grate, and after entering the furnace, the flame is refracted upwards and then turned to the front smoke box through the combustion chambers on both sides of the body, and then the front smoke box is folded back into the inner tube bundle, and the rear smoke box is passed. Enter the economizer, then draw by the induced draft fan through the flue to the chimney to the atmosphere.
2 ton biomass boiler for sale performance characteristics:
The boiler type is a horizontal package water-fire tube boiler with a natural circulation of working fluid.
The boiler heat exchange system is composed of a drum, a left and right header, and a water-cooled wall. The main heating surface has a furnace water wall and a convection tube bundle in a part of the drum and the drum.
The boiler shaft is made of refractory concrete. The rear arch is low and long, so it burns well. The two-wing flue and the side wall brick are made of refractory sintered brick. General refractory bricks are used for the front and rear walls of the boiler.
The grate has a reasonable air distribution, the combustion chamber is large, and the fuel is highly adaptable.
The high-temperature flue gas enters the sedimentation chamber first, and then enters the two-wing flue and the front smoke box from both sides, so the effect of eliminating smoke and dust is good.
The water circulation is simple, the structure of the pressure-bearing parts is reasonable, and it can be safely operated under the condition of ensuring water quality.
