Regenerative burner is essentially a combination of efficient regenerative heat exchanger and conventional heating furnace, which is mainly composed of furnace body, regenerator, commutation system, fuel, air supply and smoke exhaust system.Regenerator is the main body of regenerative burner flue gas waste heat recovery, it is the chamber space filled with regenerator, it is a part of flue gas and air activity channel.
In heating furnace, regenerator is always used in pairs, a furnace can be used in pairs, also can be used in several pairs, even dozens of pairs.In the domestic some large heating furnace, the maximum use of 40 pairs.The furnace temperature is more and more even because the furnace temperature is evenly distributed, the heating quality is greatly improved, and the pass rate of products is greatly improved.Larger fuel selection scale is suitable for light oil, heavy oil, natural gas, liquefied petroleum gas and other fuels, especially for low calorific value of blast furnace gas, gas has excellent preheating combustion effect, expanding the application scale of fuel.
As a result, furnace fuel consumption has declined significantly.About usually large heating furnace, can save energy 25% ~ 30%;The heat treatment furnace can save energy by 30% ~ 65%.NOX production is lower choose traditional energy saving skills, the higher the temperature of combustion air preheating, the higher the NOX content in the flue gas;And the selection of regenerative high temperature air combustion skills, in the combustion air preheating temperature of up to 800℃, NOX production in the furnace is greatly reduced.
Because regenerative burners diffuse combustion in a relatively low oxygen state and have no flame base, there are not many conditions for the formation of NOX.Low NOX content in flue gas is conducive to environmental protection.Oxidation loss of metals another advantage of low oxygen combustion is that it reduces the oxidation loss of the metals being heated.In addition, the regenerative burner can also improve the flame radiation intensity, enhance the radiation heat transfer, and improve the output value of the furnace.
The above is the burner manufacturer broad heat energy for you to analyze the daily application of regenerative burner, to learn more can contact us through this site.
