Abstract

The utility model relates to a total primary air type coal gas burner which is arranged on the upper surface of a bottom plate of a closed type combustion chamber of a water heater. The utility model is composed of a base and a reverse U-shaped outer pipe. The base comprises two side folding edges, and the reverse U-shaped outer pipe is in riveted connection with the side folding edges. The domed roof surface of the outer pipe is provided with a plurality of flame holes, and the interior of the outer pipe is provided with an inner pressing plate with a plurality of through holes. The position of the base corresponding to the inner pressing plate is engaged with an air inlet duct which can extend out of the combustion chamber. The interior of the air inlet duct is provided with a mixing plate which comprises a plurality of through holes for mixing split stream. The burner can thoroughly mix air and coal gas, and prevent the backfire phenomenon and the flame lift phenomenon, and thus the utility model is suitable for the combustion chamber of a closed type water heater.

Description

Full primary air formula gas burner

The utility model is relevant a kind of full primary air formula gas burner.

Gas water heater is obtained the main source of hot water for the modern, but can mix a large amount of fresh airs during gas-fired, and discharges large quantity of exhaust gas.General gas water heater adopts open combustion chamber, the direct and surrounding air convection current of suction air when making gas-fired and combustion gas, the necessary condition when good ventilated environment becomes this type of gas water heater use.But the space is narrow and small in the city now, and the installation site of this type of gas water heater there is no sufficient airspace sometimes, add the Heaven when cold door and window close, often leak or incomplete combustion, and cause carbon monoxide poisoning event because of coal gas.

Though developed forced exhaust formula water heater at present, but its burner still adopts the adjacent formation of tens row's vertical types, must utilize for the first time, air for the second time, therefore can only be designed to open around the combustion chamber, can't improve overall security and efficiency of combustion, and the vertical type burner takies bigger height space, does not conform to ideal.

The purpose of this utility model is to provide a kind of full primary air formula gas burner, use the enclosed burning chamber of its suitable water heater, fully mixed gas and air, further cooperate clip plate to prevent from flame and tempering, and evenly burn in air feed to each flame hole, and reduce the height space of burner, correspond to actual needs.

For reaching above-mentioned purpose, the utility model provides the plate upper surface of the enclosed burning chamber that a kind of burner is arranged on water heater, described burner is to be made of a base and an inverted U-shaped outer tube, and described base contains two side edgefolds, and described inverted U-shaped outer tube riveted joint thereon; The arc top surface of described inverted U-shaped outer tube is preset a plurality of flame removing holes, and outer tube inside is provided with the clip plate of a plurality of through holes of a tool; Described base has an air induction conduit extended combustion chamber, that supply to introduce coal gas and air with respect to engaging on the position of described clip plate; Described air induction conduit inside is provided with one and contains the mixed plate of a plurality of shuntings mixing with through hole.

In preferred embodiment, described clip plate one side is fixed on the inner surface of described base one side edgefold, and its another side is towards the described base opposite side segment distance that overhangs out.

In another possible embodiments, above-mentioned air induction conduit is located near on the bottom surface of base one side edgefold, perhaps directly be located on the surface of base one side edgefold, and the default a plurality of long trough through holes of the mixed plate periphery of air induction conduit, make a bottom flange in mixed plate bottom surface centre in addition.

Is to reach technological means and the characteristics that above-mentioned purpose adopts from following conjunction with figs. to understanding the utility model the description of described embodiment; Wherein:

Fig. 1 is the structure chart that the utility model embodiment gas burner is applied to water heater:

Fig. 2 is the amplification stereogram of Fig. 1 gas burner;

Fig. 3 is the exploded view of burner shown in Figure 2;

Fig. 4 is the sectional view of burner shown in Figure 2 and represents it and the relevant position of jet for gas;

Fig. 5 is the view that many group burners are arranged in juxtaposition; And

Fig. 6 is the sectional view of another embodiment of burner.

At first, see also Fig. 1, the utility model gas burner 40 is specialized in forced exhaust formula water heater and is used, this water heater main body 10 can form a closed admission space 11 basically, inner housing 20 then constitutes a closed exhaust space 21, combustion chamber 24, heat collector 25 and exhaust blower 26 wherein are set from lower to upper, and admission space 11 and the default respectively air inlet 12 of exhaust space 21, an exhaust outlet 22.Horizontal burner 40 is fixed in base plate 23 upper surfaces of enclosed burning chamber 24, and down passes an air induction conduit 80, attract flowing into air, and the coal gas that sprayed of the jet for gas on the admission space base plate 13 30.

Burner 40 has a long base 50 shown in Fig. 2,3, this base 50 contains two side edgefolds 51,52, and folds out willow continuously along whole base 50 and two side edgefolds 51,52 and connect with lip limit 53.One 60 of outer tubes that roughly are made as inverted U have both-side opening end 61,62, and periphery folds the lip 63 that becomes to match continuously, make base 50 and outer tube 60 riveted joint combinations, to form specific volume space, at the then default a plurality of flame removing holes 64 of the nose-circle cambered surface of outer tube 60.One clip plate 70 is parallel every being located at outer tube 60 inside, and the prefabricated a plurality of exhausting holes 73 of its arc surface.Cooperate and to consult Fig. 4, these clip plate 70 1 sides 71 are fixed in the surface of base 50 1 side edgefolds 51, make its another side 72 segment distance that overhangs out.And base 50 is with respect to the air induction conduit 80 of the engagement position one extended combustion chamber of clip plate 70, for introducing coal gas and air.

In preferred embodiment, this air induction conduit 80 is located at the place, bottom surface near base 50 1 side edgefolds 51.And air induction conduit 80 inside are provided with one and contain a plurality of shuntings and mix mixed plate 81 with through holes 82, and these through holes 82 can be located at mixed plate 81 peripheries, and make oval arc groove shape; Then make a bottom flange 83 in mixed plate 81 bottom surface central authorities in addition.Shown in Fig. 4,5, burner 40 can be organized spacing parallel arranging on the base plate 23 of combustion chamber more, by exhaust blower 26 continuous runnings shown in Figure 1, then the air of admission space and jet for gas 30 spray coal gas and flow into air induction conduit 80 together, accept 360 degree shuntings of bottom flange 83 with the through hole 82 of mixed plate 81 immediately, coal gas is fully mixed with air, flow to clip plate 70 spaces and each through hole 73 again to reduce flow velocity, can prevent tempering, from the flame phenomenon, further evenly burn in air feed to each flame hole 64 of outer tube 60.

In another possible embodiments, as shown in Figure 6, the horizontal air induction conduit 800 of employing level is arranged in the surface of base 50 1 side edgefolds 51 with air induction conduit 800, promptly applicable to the gas inlet of horizontal direction spray feed.

Comprehensive the above, the utility model " full primary air formula gas burner " fully mixing air, coal gas burning, and prevent tempering with from the flame phenomenon, and reduce height space, be fit to the use of closed water heater combustion chamber.
