Introduction of five major systems for biomass boilers

2019-10-14

The reason why biomass boilers are different from other boilers is mainly the difference in their internal systems. Biomass boilers mainly consist of five major systems. Today, the professional technicians who have been engaged in the production of boilers for many years explain the main components of this boiler.

1, the combustion system, which is a more important part of all systems, the combustion system consists of burners, fans, igniters and other components. The biomass fuel first has a preheating process in the burner, and then the fuel is delivered to the furnace through the fan for combustion. BMF fuel contains a high amount of volatile matter. When the temperature in the furnace reaches the precipitation temperature of its volatile matter, the ignition of the igniter fuel can be quickly ignited under the condition of supplying air. 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 vaporized. The adjustment of the boiler load is controlled by the adjustment of the feed amount. The flue gas after combustion enters the convective flue through the furnace to exchange heat, and then enters the dust collector for purification treatment, and finally discharges to complete the entire combustion and heat transfer process.

2. Feeding system, feeding system consists of silo, vibrating feeder, screw feeder, spiral feeding tube and other components. The BMF fuel processed in the factory is transferred to the silo by 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 feeding and material conveying, a vibrating feeder is connected between the silo and the screw feeder.

3. Smoke system, air supply system: The boiler air supply system is integrated with the burner, and the air is sent to the furnace through the blower through the blower to achieve the function of conveying fuel and supporting combustion.

4. Soot blowing system, the boiler is equipped with a fully automatic soot blowing device, which can periodically purge the furnace and the pipe to ensure that no dust is formed on the surface of the pipe, thus achieving safe and efficient operation of the boiler.

5. Leading dust removal system: Under the action of the induced draft fan, the high-temperature flue gas generated after the completion of combustion passes through the convective heat transfer in the pipe to enter the dust collector for purification, and finally is exhausted by the chimney by the induced draft fan.
