Biomass burner body description
 The LSJ series biomass pellet burner is designed and developed based on the customer's many years of experience and the extensive design experience and operating experience of most biomass burner manufacturers on the market, based on fuel characteristics and combustion characteristics.
1: fuel supply
     The main fuel of the burner is 3mm or less of biomass sawdust, wood chips, rice husks and the like. The fuel is delivered by the loader to the split silo and then sent to the rear of the combustor for combustion via a multi-stage feed system.
2: Choice of combustion method
According to the requirements of environmental protection, clean combustion, and the combustion characteristics of biomass fuel, the boiling semi-gasification combustion plus tangential swirling air distribution design is selected.
3: anti-tempering device
    In order to avoid the equipment failure during the operation of the equipment and the misoperation of the equipment, the silo is tempered. For this technical problem, each electronic control and machinery of the company has anti-tempering function.
4: Furnace material
    The interior high-alumina refractory bricks, the external castables are integrally poured, fixed intervals, expansion gaps, practical calculations, and reasonable distribution.
5: Sealing, corrosion, dust accumulation measures
    Burner tightness is very important to the burner. It not only maintains the safety and cleanliness of the burner, but also improves the thermal efficiency of the burner. The burner of this product adopts multi-layer insulation layer, (outer membrane type water-cooled, air-cooled wall, designed according to customer's requirements) two-layer guard plate, water-cooled welded joint pressure test to ensure the tightness of the burner. The reliability of the burner operation is guaranteed.
    Because the biomass fuel contains various salts including chloride, the flue gas generated by combustion has strong corrosiveness. After years of practical experience, the company uses high-aluminum refractories with high temperature and corrosion resistance as the inner tank and gun. The mouth is a split structure, and the interior is a high-aluminum pouring material.
    The ash of the heated area is related to the flow rate of the flue gas, the dew point temperature, the structural arrangement and other factors. According to practical experience, the ash content of the biomass fuel combustion is lower, has a strong adhesion, and is easy to adhere to the heating surface. Therefore, On the structure of the furnace, the grate of our company adopts the wind disk structure. During the operation, the flame of the furnace turns into a cyclone shape, and the ash gathers in the middle of the bottom. The upper and lower sides of the wind disk have gray outlets.
 
Control section
    The electronic control programming system of this series is designed and developed independently by our company for biomass burners. The control system adopts PLC and touch screen. The internal program matches the burner one-to-one, which has the advantage of automation.
1: wiring voltage
The burner electronic control system is a power supply line, working voltage AC380V 50HZ three-phase four-wire.
2: Electrical configuration
Electronic control system components PLC, touch screen, select Delta ES2, DOP series, global warranty.
3: Control mode
Each motor is controlled separately, with manual and automatic functions. It can automatically adjust the feeding and distribution according to the temperature and pressure required by the customer. The multi-segment automation intelligent control can realize the one-button start-up and the one-button delay shutdown. The complicated operation of the burning machine in the market greatly saves human resources.
4: silo detection, lack of material alarm
Detect the condition of the burner silo according to the amount of material in the silo. When the fuel is sufficient, the burner is running normally. When the fuel is low to the normal critical point, the device prompts the material shortage alarm and the touch screen displays.
5: Status real-time detection
Each motor is controlled separately, adding overload phase protection, communication PLC, touch screen. When the motor fails, the buzzer sounds a light and light alarm, and the fault location is accurately displayed on the touch screen. More one-button self-recovery system.
6: Temperature and pressure protection
    Install a temperature controller and an electrical contact pressure gauge on the heat source equipment. The burner automatically adjusts the protection according to the parameters set on the meter. Once the set temperature and pressure alarms are exceeded, the burner is automatically adjusted to the safety parameter position.
