The selection of burners for oil-fired and gas-fired boilers should be selected according to the structural characteristics and performance requirements of the boiler body and fuel characteristics, combined with the user's operating conditions. As the combustion equipment of fuel oil and gas boilers, the burner's main functions are:
1) Provide the fuel oil or gas required by the boiler, and choose the oil atomization method for the oil fuel to increase the distance between fuel and air
Contact area. For gaseous fuel, the combustion method should also be selected.
2) Supply the air necessary for combustion to achieve full mixing of air and oil mist or gas to ensure complete combustion.
3) Ensure rapid ignition and stable combustion.
4) Realize the automatic control of program ignition and combustion process.
The burner power calculation method of the boiler is for your reference.
Burner power = fuel consumption x fuel calorific value
Burner efficiency = burner output power / fuel consumption × fuel calorific value.
Burner power is generally >99%
Boiler efficiency = boiler output power / fuel consumption × fuel calorific value
Boiler efficiency is generally 85-90%
The thermal efficiency of hot water boiler is generally 90%
The thermal efficiency of steam boiler is generally 85-87%
Burner power = boiler power / boiler thermal efficiency
