Low Nitrogen Oxide (NOx) Burners - ALZETA
ALZETA can assure minimal nitrogen oxide formation for all our burner products. Low NOx Combustion Process. Common to all burners is premixed surface-stabilized combustion. This is a two-step combustion processfirst the fuel and air is premixed then
Principle of low nitrogen burners(the newest one)_bntet burner
Precombustion chamber development research in China in recent 10 years is a kind of high efficiency and grade of low NOx combustion technology generally speaking a precombustion chamber of the wind or secondary air and fuel injection system etc the mixed fuel and a wind in a form in the combustion zone precombustion indoor fuel mixture due to the lack of oxygen is only part of the fuel combustion fuel in poor oxygen and low
Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound nitrogen). When low NOx oil is fired in firetube boilers utilizing flue gas recirculation NOx reductions of 60%-70% over NOx emissions from standard No. 2
Being a gas atomisation is not an issue and proper mixing of gas with the appropriate amount of air is all that is required for combustion. Two types of gas burner are in use Low pressure and High pressure. Low pressure burner. These operate at low pressure usually between 2.5 and 10 mbar.
(3) Due to high heat transfer rates there is a considerable reduction in boiler size. (4) FBC boiler can burn low grade fuels efficiently. (5) Low fuel bed temperatures upto about 954°C which means that there is less nitrogen oxide emissions and fewer problems caused by ash agglomeration.
