(1) Diffusion burners are classified according to primary air coefficient. There is no premixed air in the gas, and the primary air coefficient a'=0. The 2-part premixed burner is often also called an atmospheric burner. a=0.45~0.75.3 Completely premixed burner, also known as flameless burner. Primary air coefficient a202) classified according to air supply method
D Natural induced draft burner. Relying on the negative pressure of the furnace to draw ambient air into the combustion area for combustion 2 blast burners. Use blower equipment to force air to the reaction area
3 pilot burners. Usually, the negative pressure formed by the high-speed flow of gas is used to inject air for mixing. Air jets can also be used to inject gas.
(3) Classification according to gas supply pressure
D low pressure burner. The gas pressure is below 5000Pa and the gas pressure is higher than 5000Pa.
1) Able to achieve the required heat load and meet normal heating requirements
2) Stable combustion. When the gas pressure and calorific value fluctuate within the normal range, tempering and de-firing will not occur.
3) Complete combustion, high efficiency and little environmental pollution. Strictly control the emission of pollutant gases and comply with national standards. A higher level of combustion efficiency helps control the greenhouse gas CO. emissions
4) Compact structure and low metal consumption. The structure is compact and easy to arrange the burner. For large-scale production, metal consumption must be considered to control production costs.
5) Easy to adjust and low noise.
