Biomass boiler is a kind of biomass boiler, that is, the boiler called biomass boiler with biomass energy as fuel, which is divided into biomass steam boiler, biomass hot water boiler, biomass hot air furnace, biomass thermal oil furnace, vertical biomass boiler, horizontal biomass boiler and so on.

Biomass boiler is a kind of biomass boiler, that is, the boiler that uses biomass energy as fuel is called biomass boiler, which is categorized into biomass steam boiler, biomass hot water boiler, biomass hot air furnace, biomass thermal oil furnace, vertical biomass boiler, horizontal biomass boiler and so on.

Classification of biomass boiler:Horizontal biomass boiler, vertical biomass boiler. Biomass gas heat transfer oil furnace, biomass steam boiler, biomass hot water boiler, biomass heat transfer oil furnace.

The boiler adopts the most suitable combustion equipment for biomass fuel combustion ---- reciprocating grate. Boiler in the structure design, relative to the traditional boiler chamber space is larger, while the arrangement of a very reasonable secondary air, in favor of biomass fuel combustion instantaneous precipitation of a large number of volatile components fully combusted.

The boiler can be equipped with fuel oil (gas) ignition burner to realize ignition automation. The feeding, combustion, slag removal, water supply and ignition of the boiler can be controlled automatically, which is very convenient to operate. The boiler is equipped with an automatic ash cleaning device, which can remove the accumulated ash on the heating surface of the boiler in time to ensure efficient and stable operation of the boiler. The boiler is equipped with a coal economizer at the end of the boiler, and an air preheater can also be arranged according to the user's needs. Compared with the traditional boiler, the boiler has higher efficiency and lower exhaust temperature.

Adoption of high efficient insulation materials, low boiler surface temperature, heat loss is negligible. Strictly manufactured in accordance with Chinese national codes and standards, all pressurized parts are made of high quality boiler steel. Each boiler undergoes strict inspection and testing before leaving the factory, including hydraulic test and X-ray test. It is set with manholes, inspection doors and fire viewing holes, etc., which makes maintenance very convenient. The biggest feature of biomass boiler is:energy saving, environmental protection, and easy to install and use.

Fuel supply

The fuel of the boiler is BMF fuel, which is fed into the top silo of the furnace by the feeder, and then fed into the furnace by the screw feeder, and evenly scattered on the grate.

Combustion process

The fuel is fed into the furnace chamber by the screw feeder, where it is gradually preheated, dried, ignited and burned due to the action of high temperature flue gas and primary air, during which a large amount of volatile matter is precipitated and combustion is intense. The high-temperature flue gas flushing the main heating surface of the boiler, into the boiler tail heating surface economizer and air preheater, and then into the dust collector, and finally discharged into the atmosphere through the chimney. The ungasified fuel moves sideways to the back of the grate until it is burned out, and the last remaining small amount of ash falls into the slag removing opening at the back of the grate.

Environmentally friendly emissions

The ash produced by BMF combustion accounts for about 1.5% of the fuel. In order to facilitate ash removal, the boiler is equipped with a spiral slag remover at the rear of the boiler to realize continuous ash removal. The flue at the rear of the boiler is equipped with a dust collector to ensure that the smoke and dust emission meets the requirements of environmental protection.

Boiler efficiency

The efficiency of the biomass boiler is generally above 80%. The boiler model is large, and the combustion is more fully, and the efficiency of the boiler is also higher. The highest reached 88.3%, 15% higher than the average efficiency level of coal-fired boilers.
