A burner is provided, including a furnace cover, a next cycle sleeve connection, a cylindrical stirring rod between them to stir air and gas, a casing to feed air and gas, and a cylinder of the mixing rod to be provided with a certain threonine EADS.The surface of the groove is grooved, and the upper top diameter of the hood is smaller than the bottom diameter of the lower section.The central hole of the air outlet is distributed in the threaded groove of the cylindrical air mixing rod.With the advantages of better mixed gas generation rotary mixed air flow, high speed flame tornado, gas combustion full, concentrated firepower, no obvious heat emission burner, simple structure, energy saving 30% high, carbon emissions reduced by about 90%.

A burner is a device that causes a mixture of fuel and air to be burned in a certain way.According to its kind and application field, burners are divided into industrial burners and civil burners.According to the fuel can be divided into pulverized coal burner, oil burner and gas burner.Gas burners are mainly divided into two categories: natural gas burners and blast furnace gas burners.Large - capacity natural gas burners mostly adopt multi - gun air inlet.Gas gun in air conditioning duct.Blast furnace gas burner is often in the combustion of hot channel, and then sprayed into the combustion chamber, due to its low calorific value, the difficulties in the fire, the structure of the existing gas burners uneven distribution of air and gas, the incomplete combustion gas, the fuel gas combustion heat and fire, have a lot of heat (energy), lead to low energy efficiency, it is worth to improve.
In view of the above shortcomings, our company provides a burner, which can better cooperate with rotating mixed air generated through air and waste gas, produce high-speed flame tornado, its combustion fully concentrated firepower, no obvious heat emission, simple structure, energy saving up to 70%, carbon emissions will be up to 90%.
The technical scheme is as follows: the burner, including the furnace head cover, with the circular sleeve under the furnace cover, and a cylindrical stirring rod, is placed between the furnace cover, the sleeve and the sleeve to stir the gas.The cylinder surface of the mixing rod is provided with the number of cylinders.The characteristics of the groove are that the diameter of the top of the furnace cover is smaller than the diameter of the bottom of the lower section and the central hole of the exhaust air is distributed in the groove of the cylindrical air mixing rod.
Compared with existing technology, it has the advantage of producing mixed gas with better rotating mixed air flow, producing high-speed flame tornado, full gas combustion, concentrated fire, no obvious heat emission burner, simple structure, energy saving up to 70%, carbon emission reduction of 90%.
