How are burners classified
Jul 23, 2024
一. Based on the fuel, they are generally divided into: gas, oil, and dual fuel.
1. Gas can be divided into natural gas, city gas, liquefied gas, etc.;
2. Oil can be divided into light oil, heavy (residue) oil, etc.;
3. Dual fuel can be divided into light oil/natural gas, heavy oil/natural gas, etc.
二. Based on the place of use, they are divided into: land use, ship use (classification society certification required).
三. Based on the structure, they can be divided into: integrated burner, split burner.
四, there are many types of combustion, classified by the combustion method:
1. Distributed burner (the air required for combustion is not pre-mixed with the gas);
2. Atmospheric burner (part of the air required for combustion is pre-mixed with the gas);
3. Thorough premixed burner (all the air required for combustion is pre-mixed with the gas);
4. Induction burner (air is sucked in by the gas jet or gas is sucked in by the air jet);
5. Natural air supply burner (relying on the negative pressure in the furnace to suck in air for combustion);
6. Blast burner (using a blast device to send air into the furnace for combustion);
7. Pure gas burner (limited to burning gas);
8. Gas + oil combined burner (can burn gas or oil at the same time or separately);
9. Gas + pulverized coal combined burner (can burn gas or pulverized coal at the same time or separately);
10. Low NOx burner (low nitrogen oxide emissions).
五. Scope of use of burners: All equipment or occasions that use liquid and gaseous fuels as energy and directly use their heat energy can be applied, such as: hot water boilers, steam boilers, industrial furnaces, combustion furnaces, road construction machinery, direct-fired air conditioners, etc.
六. Basic requirements for burners: safe operation, energy conservation, and environmental protection.
七. The three elements of the combustion process are: fuel, oxidant and ignition source (here refers to the process of industrial combustion to quickly oxidize hydrocarbon fuels to produce a large amount of energy for industrial heating).
八. General atmospheric air as the oxidant of fuel (O2 accounts for about 21% of the volume): In some use occasions, the oxidant content is less than 21% O2 (such as gas turbines with flue gas recirculation) or more than 21% O2 (such as oxygen-enriched combustion).
九. Six parts involved in the industrial combustion process:
1. Industrial burner, 2. Load, 3. Furnace (boiler, dryer, etc.), 4. Waste heat recovery installation (air preheater, etc.), 5. Control system (combustion and load control), 6. Air pollution prevention and control system (dust removal, etc.).
There are too many types of burners, which can be selected according to different needs. No matter what problems you have in the process of selecting industrial burners, SWT Burner's professional after-sales team is always here to help you!www.burners-china.com
