Generally speaking, the size of external ring fire cover with and top fire hole number and position determined the degree that firepower is concentrated and the situation of burning.If fuel difference, gas-cooker power difference, then the condition of the formation of its CO and NOx is different with the position, then the parameters such as number of external ring fire cover and fire hole are just different, by adjusting its relative dimensions, make fuel in suitable zonal combustion, both helped burning fully, can suppress the generation of NOx again, to reach the high-efficiency cleaning burning.
When the present invention works, burner base places on the panel, need not out fresh air inlet above the panel, fuel is by two jet pipes and the ejection of center gas nozzle, injection portion of air (primary air) enters mixing chamber by the side induction tunnel under certain pressure, and enter middle internal heat lid by the center induction tunnel, fuel under certain pressure respectively by two jet pipes on the combustion gas injection pedestal and the ejection of center gas nozzle, then the external ring fire cover of installing from mixing chamber top and internal heat cover the fire hole ejection of face, auxiliary air can be replenished by burner base top air admission hole, the auxiliary air demand is not high, makes the size of external ring fire cover suitably to reduce, and has increased the time of contact of high-temperature flue gas and pot face, reduce energy loss, make heating more even, heat absorption efficiency is higher, and CO and NOx discharging are all very low.
Distance between side induction tunnel inlet central horizontal face of the present invention and the burner base tonifying Qi hole lower surface shortens to 20~24mm, make the distance that enters the mouth from the air approaching side induction tunnel on panel top shorten, two jet pipe diagonally opposing corners are arranged, near induction tunnel, played gather qi together, strengthen the effect of induction tunnel ejector capacity, under the identical situation of gas quantity, strengthened the air intake ability, make that the air content in the gaseous mixture increases behind the injection.Induction tunnel rear portion bending makes combustion gas and air further spread mixing simultaneously, and it is more even to make that the mist that enters mixing chamber mixes, and it is more abundant to burn, and gas-cooker power increases, and meets the requirement of compatriots' cooking needs vigorous fire.
Owing to need not out fresh air inlet above the panel, the enclosure interior that can not enter into easy-clear not or cleaning of soup juice and foreign material or small insect and so on can breed bacteria or peculiar smell, helps consumer's health.
Proof adopts gas-cooker of the present invention by experiment, and the heat absorption efficiency of pot face has reached 55%, and the CO discharge capacity is below 400ppm simultaneously, and the NOx discharge capacity requires index far below national energy-conserving and environment-protective below 300ppm.
