1. Technical requirements and classification of burners
Burner: A general term for devices used to achieve the combustion process
Basic purpose: Reasonably organize the combustion process to ensure that the thermal work of the combustion chamber meets the requirements of technology, technology and economy.
skills requirement:
A: Have a certain heat load to meet the heat required for heating or combustion temperature B: Certain flame characteristics (ignition concentration, temperature, burning speed), stable flame
C: High combustion efficiency - complete combustion
D: The burner is equipped with necessary automatic adjustment and automatic safety devices - automatic control
E: Less smoke toxins - safe and environmentally friendly
F: Compact structure, safe and reliable, low cost.
2. Classification
According to one air distribution: diffusion type, atmospheric type, complete premixed type
According to the air supply method: ejection type, blast type, natural induction type
Divided by gas pressure: low pressure, high (medium) pressure
According to the flame shape: straight flame, flat flame, adjustable flame
According to the flue gas outlet velocity at the fire channel: low speed (50m/s) high speed (200~300m/s)
