Boiler combustion process

Boiler combustion process

The fuel is fed into the furnace by a screw feeder, where, due to the action of high-temperature flue gas and primary air, drying, ignition and combustion, the fuel is gradually preheated. During this process, a large amount of volatile substances precipitated out and burned fiercely. After the generated high-temperature flue gas washes the main heating surface of the boiler, it enters the economizer and air preheater on the heating surface at the rear of the boiler, then enters the dust collector, and finally is discharged into the atmosphere through the boiler. chimney. The ungasified fuel moves to the back of the grate until it is burned, and finally a small amount of ash and slag falls into the slag outlet behind the grate.

Boiler fuel supply

The fuel of the boiler is biomass fuel, which is sent from the feeder to the top of the furnace, and then sent to the furnace by the screw feeder, and is evenly distributed on the furnace rate.

Features of BMF boiler:

The boiler adopts combustion equipment that is most suitable for biomass fuel combustion grate. In terms of structural design, the boiler has a larger furnace space than traditional boilers. At the same time, a very reasonable secondary air arrangement is conducive to the complete combustion of a large number of volatile components, which are released instantaneously during the combustion of biomass fuel.

The control system adopts high-brightness, full Chinese display, and adopts a famous-brand PLC control system as the central control unit; exchanges information with boiler users through man-machine dialogue, and realizes the fully automatic, safe and reliable operation of the biomass pellet boiler. The boiler can be equipped with an oil (gas) ignition burner to realize ignition automation. The feed, combustion, slag removal, water supply and ignition of the boiler can be automatically controlled, and the operation is very convenient. The boiler is equipped with an automatic dust removal device, which can remove the dust on the heating surface of the boiler in time to ensure the efficient and stable operation of the boiler.

An energy saver is installed at the end of the boiler, and an air preheater can also be installed according to user needs. Compared with traditional boilers, this boiler has higher efficiency and lower exhaust gas temperature. Using high-efficiency insulation materials, the surface temperature of the boiler is low, and the heat dissipation loss is negligible. It is produced in strict accordance with China's national norms and standards, and all pressure parts are made of high-quality boiler steel.

Each boiler must undergo rigorous inspection and testing before leaving the factory, including water pressure test and X-ray inspection. Provide manholes, inspection doors, fire-proof holes, etc. for easy maintenance.

The biggest feature of BMF boiler is: energy saving, environmental protection, easy to install and use.
