Fire distributor with two variable fire hole airway characteristics

Abstract

The invention relates to the technical field of gas stove fire distributors, and particularly discloses a fire distributor with two variable fire hole airway characteristics. The spacing between the top of a second comb tooth groove and the root of the second comb tooth groove gradually widens, the spacing between the top of a first comb tooth groove and the root of the first comb tooth groove gradually narrows, the gas flowing out of a second gas outlet has low pressure and low flow rate, the gas flowing out of a first gas outlet has high pressure and high flow rate, the mixed gas with lowerpressure and low flow rate burns near the inner wall of the fire distributor, the mixed gas with high pressure and high flow rate burns in a combustion chamber away from the fire distributor, the combustion flame is in the shape of mountain peaks and valleys and is in a high-low staggered form, and the high-low staggered flame and the swirling resident heat are intertwined and integrated more closely. The contact strength and contact surface between the mixed gas flow and the heat released by combustion are increased, the heat utilization efficiency is high, the combustion reaction space utilization rate of the combustion chamber is higher, and thus the combustion reaction speed, combustion reaction temperature and reaction intensity are improved.

[0002] Burner firearms made of stainless steel plates are popular because their materials are not prone to oxidation and corrosion and have high sensory value. One of them is made of two sets of circular discs processed by stainless steel plates, and then alternately stacked and combined in sequence. Cylindrical fire divider, because a group of annular discs forming the fire hole and air passage are mostly formed by circumferential corrugated plates, and the other group of annular discs is formed by flat plates, and the two sets of annular discs are alternately stacked in sequence to form a divided The fire hole channel is formed between the front and back grooves of the firearm and the wave plate and the flat plate surface. Since the inlet and outlet geometric characteristics of this type of fire hole channel are almost the same, when the mixed gas circulates at the entrance and exit of the fire hole channel The resistance is almost the same, and the resistance of the mixed gas is almost the same when it flows through the inlet and outlet of the fire hole, so that the pressure and flow velocity of the mixed gas are almost the same when it flows out, and the pressure and flow velocity of the mixed gas flowing out from the outlet of the fire hole are the same, so that the initial period (can be Depending on the state) the combustion flame is evenly distributed near the exit of the fire hole, so that the overall state of the combustion flame in the initial stage (visible state) is in a regular circular cylindrical shape, and the overall state is in a regular circular cylindrical shape. The combustion flame determines the relative combustion chamber There is basically no work done by the initial flame in the central area. Experiments show that the volume of the uniform circular cylindrical visible combustion flame accounts for a relatively small proportion of the total volume of the combustion chamber, and the proportion of the relatively small volume is relatively concentrated. When the outer ring of the combustion chamber is close to the exit of the fire hole, it is difficult for the mixed gas that flows out relatively concentratedly to quickly and fully absorb the heat required for the combustion reaction in a larger area, and it is easy to reduce the combustion reaction speed and reaction intensity. The flame temperature is lower, and the quality of the combustion reaction is not high
