What is a biomass burner? Introduction to principles and features For many customers who are buying biomass burners for the first time and people who want to know about this unfamiliar equipment, this article can have a preliminary understanding of biomass burners. Please see the details below
1. What is a biomass burner? The composition of main components and explanation of technical terms
(Biomass particles, peanut shell briquettes, wood chips, wood blocks, etc.), can be fed at one time to avoid continuous filling.
2. The main body of the biomass combustion chamber: mainly used for combustion and gasification of biomass fuel (biomass particles, peanut shell briquettes, wood chips, wood blocks, etc.) in the biomass combustion chamber.
3. Burner nozzle (burner): The nozzle is divided into inner tube and outer tube. The inner tube is used to absorb the temperature of the burning flame, and the outer tube is used to connect to coal-fired boilers, gas boilers, dryers and other combustion equipment.
4. Burner grate: The bottom of the combustion chamber can be divided into two categories: fixed grate and movable grate.
5. Slag cleaning door: According to the ash content of the fuel, the biomass burner should open the furnace door every 2 to 8 hours to clean the ash on the grate. When opening the furnace door, be sure to stop the blower for more than 10 minutes and stand still. On the side of the furnace door, keep a safe distance of more than 2 meters, and open it with a long iron rod after the blower stops running. It can be cleaned only when there is no flame and combustible gas ejected from the furnace door.
6. Blower: Provide air distribution for biomass fuel combustion, oxygen distribution for secondary combustion, and air required for other places that require air-cooling to cool down and flame-retardant.
7. Wind box: used to adjust air volume and air pressure.
8. Bottom air: fed from the bottom of the grate.
9. Secondary air: the interlayer distribution between the inner tube and the outer tube of the crater, and the secondary full combustion of the combustible gas in the combustion crater.
10. Feeding motor: used to drive the screw rod of the feeding system.
11. Feeding system: Send biomass pellet fuel into the combustion chamber.
12. Casters: Used for short-distance movement of the burner (please use a forklift for a long distance to avoid damage to the rigid vibration refractory layer).
13. Fuel: Pure woody biomass pellet fuel, with a diameter of 8--10mm, a length of less than 30mm, a calorific value of more than 3500KCal, and an ash content of less than 3%. (Large tonnage burner can burn 30mm biomass briquette fuel)
2. The working principle of the biomass burner:
The basic working principle of the biomass burner (fuel is pellets, briquettes, wood chips, etc.) is: the biomass burner mainly includes a biomass burner body, a feeder, multiple air distribution systems, and an electric control system (man-machine interface, PLC intelligent detection control) and other components. The combustion chamber of the burner is a two-stage combined type. The biomass fuel enters the high-temperature cracking semi-gasification combustion chamber in two stages through the automatic feeding system, and the air is distributed multiple times. The gasification device is fed from the lower part of the furnace to form a suspension type Semi-gasified combustion and rapid cracking reaction produces high-temperature gas. This process will produce precipitates and intermediate products such as H2, CH4, CmHn, CO and other combustible components. The temperature reaches above 1000 ° C. It will enter the combustion chamber of oxygen for suspension, gasification and combustion, and enter the supporting heated equipment through the combustion nozzle to flush the boiler. The heating surface replaces traditional energy sources such as coal, diesel, and heavy oil to do work. At the same time, the gasified carbon blocks continue to burn under the action of the original boiler blower until they are completely burned and fall into the ash chamber.
3. Working characteristics of biomass burner:
(1) Energy saving, environmental protection and intelligence.
(2) Semi-gasification combustion method, high combustion efficiency;
(3) The combustion flame temperature is high, which can be used to replace diesel burners, natural gas burners, and heavy oil burners.
(4) The flame ejected from the crater will contain a small amount of ash during combustion. When in use, a soot cleaning port should be reserved on the heat exchange equipment (such as heat exchangers, aluminum melting furnaces, etc.).
(5) The flue gas emission contains very little sulfide, which is far below the national standard.
The above is what the biomass burner is, its principle and its characteristics.
