Feeding system

　　The feeding system is composed of silo, vibrating feeder, screw feeder, screw feeding tube and other components. The BMF fuel processed in the factory is transferred to the silo through a belt conveyor, and then the BMF fuel in the silo is supplied to the burner for combustion through a screw feeder. In order to ensure the stability of continuous unloading and material conveying, a vibrating feeder is connected between the silo and the screw feeder.

Combustion System

　　The combustion system consists of burners, fans, igniters and other components. Biomass fuel first has a preheating process in the burner, and then the fuel is delivered to the furnace for combustion through a fan. BMF fuel contains high volatile matter. When the temperature in the furnace reaches the precipitation temperature of its volatile matter, the igniter fuel can be quickly ignited and burned under the condition of air supply. The burner temperature control is based on the internal temperature of the furnace, and its temperature is related to the amount of air supplied when the fuel is gasified. The adjustment of the boiler load is controlled by the adjustment of the feed rate. After combustion, the flue gas enters the convection flue through the furnace for heat exchange, then enters the dust collector for purification treatment, and is discharged to complete the entire combustion and heat transfer process.

Soot blowing system

　　The boiler is equipped with a fully automatic soot blowing device, which can periodically purge the furnace and flue pipes to ensure that there is no dust accumulation on the surface of the flue pipes, so as to realize the safe and efficient operation of the boiler.

Smoke and wind system

　　Air supply system: The boiler air supply system is integrated with the burner, and the air is sent to the furnace through the burner through the blower to deliver fuel and support combustion.

　　Induced air dust removal system: Under the action of the induced draft fan, the high-temperature flue gas produced after combustion is purified by the convection heat exchange in the flue pipe, and then discharged from the chimney through the induced draft fan.

Automatic control system

　　The control system adopts high-brightness, full Chinese display, and uses PLC control system as the central control unit; exchanges information with boiler users in the way of man-machine dialogue, realizing automatic operation of BMF boiler
