A burner type

At present, there are about gas products of China's manufacturing industry production, the use of the gas stove burner with five kinds of methods: 1, round hole vertical burning fire into the fire hole, highly inconsistent, center fire and outer ring fire cross state; 2, the circumference of the trapezoidal slot type oblique thrust combustion; 3, the inner cone type slot oblique thrust combustion; 4, burning cone gap type oblique thrust combustion; 5, cohesive rotary combustion.


two combustion state and five kinds of burner
The first round of fire hole vertical straight way combustion: improve the thermal efficiency of the burner is on the pan to solve the bending flame, the flame height, the inner ring and the outer ring fire flame burner fire burning cross formation of carbon ion separation, and bottom carbon is serious, the result is carbon monoxide (CO) emissions is high also, emissions of nitrogen oxides (NOx), high thermal efficiency is low.

Second kinds of circular trapezoid groove oblique thrust combustion: high temperature combustion around the bottom, middle bottom temperature is low, the result is carbon monoxide emissions meet the national standard requirements, however, low thermal efficiency and high emissions of nitrogen oxides (NOx).

Third cone slot type oblique thrust combustion: flame combustion modeling is cohesion, inner cone state, each flame level of disparity is large, outside air into the burner flame root zone is difficult, the two air supply flame root zone, thermal efficiency and carbon monoxide emissions meet the basic requirements of GB, but nitrogen oxides (NOx) emissions are still high.

Fourth kinds of combustion cone slot type oblique thrust combustion: flame were cone flame state, the level of disparity two times larger, air enters the flame root needs to climb, air supply difficulties, insufficient gas combustion, emissions of harmful gases is high, low thermal efficiency.

A fifth cohesive rotary flame is burning: tornado, the flame all together, air can not enter the flame root zone, depend on the increase of air ejecting nozzle can solve the required air gas, gas combustion is not sufficient, the kitchen gas smell thick, carbon dioxide and nitrogen oxides (NOx) emissions is still high.

Through the analysis of the above five kinds of burner effect; insufficient gas combustion will produce large amounts of harmful gases carbon monoxide (CO), is easy to produce uneven flame, nitrogen and oxygen combined with another harmful gas - generating nitrogen oxides (NOx), these two kinds of harmful gases, causing pollution of kitchen space, seriously eroding the body health, but also the thermal efficiency is low, also constitute a waste of energy.
