The dizhonghai boiler adopts the combustion equipment which is suitable for biomass fuel combustion - reciprocating grate. In the structural design of boiler, relative to the traditional boiler furnace space is large, secondary air at the same time arrangement is very reasonable, is advantageous to the biomass fuel burns instantly precipitation amounts of volatile combustion in full.

The boiler can be equipped with fuel (gas) ignition burner to realize ignition automation. Boiler feedstock, combustion, slag removal, water supply and ignition can be controlled automatically, and the operation is very convenient. The boiler is equipped with automatic ash cleaning device, which can remove the ash of the boiler heating surface in time and ensure the boiler to run efficiently and stably. The rear of the boiler is equipped with economizer, and the air preheater can be arranged according to the user's needs. Compared with the traditional boiler, the boiler is more efficient and the exhaust temperature is low.

High efficiency thermal insulation material, the boiler surface temperature is low, the heat loss can be neglected. Strictly according to Chinese national standard and standard production, all pressure parts are made of high quality boiler steel. Each boiler must undergo strict inspection and testing before delivery, including water pressure test and X-ray detection. It is very convenient to set up manhole, inspection door, fire hole and so on. The main characteristics of biomass boilers are: energy conservation, environmental protection, and convenient installation and use.


Fuel supply

The fuel of the boiler is BMF fuel, and the fuel is fed into the top bin of the furnace by the feeding machine, and then it is fed into the furnace by the screw feeder and is distributed uniformly on the grate.


The combustion process

The fuel is fed into the furnace by the screw feeder, which is heated by the high temperature flue gas and the effect of a wind, which is drying, burning, and burning. After the main heating surface of the high-temperature flue gas scour boiler, it enters the heating surface economizer and air preheater in the rear of the boiler, then goes into the dust collector, and finally enters the atmosphere through the chimney. The ungasified fuel moves towards the back of the grate until it is burnt out, and the remaining bits of ash fall into the slag at the back of the grate.
