Description

The commercial energy-saving gas burner

Technical field:

The utility model relates to a kind of commercial gas furnace, the commercial energy-saving gas burner that particularly a kind of catering industry uses.

Background technology:

Present large stove, short young stove and the Chinese meal cooking stove etc. that generally use of catering industry, its nucleus equipment is its burner, i.e. what of the height of the whole combustion apparatus thermal efficiency and Air thing discharge capacity kitchen range, the height of its efficiency of combustion have directly determined.Existing gas burner mixes after-combustion with the force air that air blast is sent here after using fuel gas to arrive the combustion zone more, and this combustion system firepower is strong, and heating is fast, but its fuel gas buring is incomplete, the CO discharge capacity is big, and efficiency of combustion is low, and energy dissipation and environmental pollution are serious; Also have gas burner use combustion gas and air through premix after tube connector passes to the kitchen range burning, also there is the danger of tempering in this incomplete combustion, the problem that efficiency of combustion is low of not only existing.

On the other hand, whether energy-conservation the thermal efficiency of kitchen range also be to weigh a kitchen range a important indicator.The gas burner of present commercial use generally is to be combined by foundry goods, and around the burner and bottom directly exposes in surrounding air.In the process that burner uses, the heat transferred burner of some fuel gas buring discharging itself, make its temperature be higher than 400 ℃～600 ℃ of environment temperatures, like this, around being lost to by around the burner and bottom, the fuel heat of quite a lot of quantity in the environment, caused the significant wastage of energy.In order to improve the thermal efficiency of gas burner, the radiation loss of reclaiming kitchen range simultaneously, people have proposed some technology and architecture advances scheme to gas burner, have further promoted the thermal efficiency of gas furnace, have also improved the firepower of gas furnace.Disclose a kind of energy-saving cooking stove head as Chinese patent CN2299235Y, the ring-shaped water jacket of a sealing has been set on kitchen range, utilized burner exhaust heat to preheat water.This energy-saving cooking stove head is simple in structure, is fit to family and uses.But what this kitchen range used is traditional Burning stove hole, only can improve the thermal efficiency, does not relate to the improvement of fuel gas buring structure, and the raising of fuel gas buring efficient is not had facilitation.

The utility model content:

The utility model discloses a kind of commercial energy-saving gas burner, overcomes the above-mentioned defective of prior art, provide that a kind of firepower is violent, efficiency of combustion is high, heat run off low, the thermal efficiency is high, the commercial energy-saving gas burner of tempering-free phenomenon.

The purpose of this utility model realizes by following technical proposal:

The commercial energy-saving gas burner comprises burner overcoat, Lu Quan, combustion chamber, kuppe, gas nozzle, cloth wind disk, combustion gas chamber, blast pipe etc.; The collar plate shape combustion chamber is fixed on cylindrical shape kuppe internal upper part; The stove circle is pressed on the outer, kuppe upper surface; The upper surface in combustion gas chamber is close to the bottom of burner overcoat, and its side is connected with gas kitchen pipe joint; It is characterized in that: the stove circle and the combustion chamber that are supported by kuppe place burner overcoat inside as one; On the lower sides of kuppe, offer fresh air inlet, on combustion chamber, evenly offer the combustion chamber through hole that runs through top and bottom, connect the air blast pipe at burner overcoat upper level; Evenly vertically arrange gas nozzle in upper surface, combustion gas chamber, gas nozzle passes the bottom of burner overcoat, and upwards is inserted in the combustion chamber through hole.

Feature of the present utility model also is:

The top of described burner overcoat is divided into whirlwind shrinkage type structure, and its top cavity volume is bigger than the lower part.

The upper surface of described burner overcoat is a little more than the upper surface 5～15mm of stove circle, and its upper surface internal diameter is than the smaller 0.5～1mm of the external diameter of stove circle.

The inside of described stove circle is the circular platform type engraved structure, is the horizontal annular rib structure all around.

The number of described gas nozzle is identical with combustion chamber through hole number, is generally 4～20, and both position consistencies from top to bottom.

Described cloth wind disc level is fixed on the inside center position of kuppe, evenly offers wind distributing hole on it, and its number is identical with the number of gas nozzle, and it is offered the position and aligns with the combustion chamber through hole.

Compare with the prior art scheme, remarkable advantage of the present utility model is:

(1) by the setting of burner overcoat, the cold air that air blast is sent into absorbs the heat radiation of high temperature furnace circle and furnace core outer wall, and the top that its cavity volume is bigger makes the speed of air intake reduce, and fully absorbs the heat radiation of high temperature furnace circle and furnace core outer wall; And be the design of the stove circle of rib-type structure by the outside, make fuel gas buring be greatly improved with the temperature of air.Providing of high temperature air must make that fuel gas buring is abundant, and firepower is more violent, and the efficiency of combustion of combustion gas is promoted greatly.

(2) descending in the burner overcoat through the high temperature air behind the pre-heating temperature elevation, after discharging by the combustion chamber through hole behind the wind distributing hole on kuppe lower end, the cloth wind disk, burn the tempering problem of having avoided premixed burning to cause with the combustion gas mixing of gas nozzle ejection again.

(3) setting by a plurality of gas nozzles is divided into some low discharge high velocity stream thighs with the combustion gas of certain flow, has strengthened combustion gas and Air mixing degree, makes that the burning of combustion gas is fierce more, has further improved the firepower of burner.

(4) the burner outer cover of She Zhiing has been avoided the heat radiation of high temperature furnace circle and furnace core outer wall, except the efficiency of combustion that improves combustion gas, has also improved the thermal efficiency of whole burner.
