Description

Energy-saving combustion chamber structure

Technical field

The utility model relates to the Thermal Equipment technical field, especially relates to a kind of energy-saving combustion chamber structure.

Background technology

Combustion chamber on the market all cooperates kitchen range to use; Situation from present market; Lack the dimethyl ether fuel gas special stove, equally also lack the special-purpose combustion chamber of dimethyl ether fuel gas, because the restriction in dimethyl ether fuel gas source; Also just not having the dimethyl ether fuel gas special stove on the market, is that combustion gas is used with the dimethyl ether but the kitchen range of other combustion gas are arranged.

Because dimethyl ether (DME) is a kind of desirable clean fuel, have good burning performance, the thermal efficiency is high; Combustion process does not have residue, no black smoke, and the CO that burning produces, the discharge capacity of NO are low; Free from environmental pollution; Because the dimethyl ether fuel value surpasses liquefied petroleum gas, and dimethyl ether so wherein is rich in oxygen, and combustion process must have certain difference with other combustion gas.

Discover; When using dimethyl ether fuel gas as the work in unity condition with existing various kitchen range; Dimethyl ether pure burning on kitchen range such as liquefied gas cooker, gas range, diesel range fire can occur taking off, leave flame, the inadequate phenomenon of burning, and is very big to the loss of energy, causes the wasting of resources.

Summary of the invention

The utility model is to provide a kind of suitable dimethyl ether fuel gas to use and improve the energy-saving combustion chamber structure of the thermal efficiency to the defective that the above-mentioned background technology exists.

For realizing above-mentioned purpose, the utility model discloses a kind of energy-saving combustion chamber structure, it comprises core body; Said core body inside is provided with air-inlet cavity, premix chamber, combustion chamber and air guide post; Said air-inlet cavity is arranged at the periphery of said premix chamber and combustion chamber, and said premix chamber is arranged at below, said combustion chamber, runs through being provided with some fumaroles on the said premix chamber; Said fumarole is communicated with said premix chamber and combustion chamber; Said premix chamber is connected with air inlet pipe, and said air guide post runs through said combustion chamber and premix chamber, offers air slot and gas port on the said air guide post; Said air slot is communicated with said air-inlet cavity and combustion chamber, and said gas port is communicated with said air slot and premix chamber.

Further, said core body cross section is " recessed " shape structure.

Further, offer air inlet on the said air-inlet cavity.

Further, said air inlet pipe runs through said air-inlet cavity and extends to the air-inlet cavity outside.

Further, said air guide column section is the T-shape structure.

In sum; The energy-saving combustion chamber structure of the utility model is provided with the air guide post through between said premix chamber and combustion chamber, running through; And on the air guide post, offer air slot and gas port; Air in the air-inlet cavity is mixed with dimethyl ether fuel gas in the premix chamber, and the heat that utilizes the dimethyl ether fuel gas burning to produce carries out preheating to the air in the air-inlet cavity, improved the generation that the thermal efficiency has prevented red flame phenomenon simultaneously.

Description of drawings

Fig. 1 is the generalized section of the utility model embodiment.

The specific embodiment

For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model, the utility model is described in further detail below in conjunction with the accompanying drawing and the specific embodiment.

As shown in Figure 1; The energy-saving combustion chamber structure of the utility model comprises that the cross section is the core body 100 of " recessed " shape; Said core body 100 inside are provided with air-inlet cavity 10, premix chamber 20, combustion chamber 30 and air guide post 40; Said air-inlet cavity 10 is arranged at the periphery of said premix chamber 20 and combustion chamber 30, and said air-inlet cavity 10 bottoms offer air inlet 11, in order to carry extraneous air.

Said premix chamber 20 is arranged at 30 belows, said combustion chamber, runs through on the said premix chamber 20 to be provided with some fumaroles 21, and said fumarole 21 is communicated with said premix chamber 20 and combustion chamber 30; Said premix chamber 20 is connected with air inlet pipe 50, and said air inlet pipe 50 runs through said air-inlet cavity 10 and extends to air-inlet cavity 10 outsides, in order to carry dimethyl ether fuel gas from the outside.

Said air guide column section is the T-shape structure; Said air guide post 40 runs through said combustion chamber 30 and premix chamber 20 and extends in the said air-inlet cavity 10; Offer air slot 41 and gas port 42 on the said air guide post 40; Said air slot 41 is communicated with said air-inlet cavity 10 and combustion chamber 30, and said gas port 42 is communicated with said air slot 41 and premix chamber 20.

When the utility model uses; Dimethyl ether fuel gas enters in the premix chamber 20 from said air inlet pipe 50; Extraneous air enters into air-inlet cavity 10 through air inlet 11 simultaneously; The part air mixes with premix chamber 20 interior dimethyl ether fuel gas through the gas port 42 of air guide post 40; Mixed then dimethyl ether fuel gas and air enter in the combustion chamber 30 through fumarole 21, and further mix with the part air that enters into combustion chamber 30 from air slot 41 and burn, the heat that burning produces through combustion chamber 30 inwalls to the air preheat in the air-inlet cavity 10; The air of preheating mixes the back and gets in the air slot 41 with the air of coming in from air inlet 11, and then mixes with dimethyl ether fuel gas and to be incorporated in combustion chamber 30 internal combustion.Since extraneous air with carried out The pre-heat treatment before dimethyl ether fuel gas mixes, improved the thermal efficiency; Mix with air before the dimethyl ether fuel gas burning simultaneously, make dimethyl ether fuel gas more fully burn, prevented the generation of red flame phenomenon.

In sum; The energy-saving combustion chamber structure of the utility model through in said

premix chamber

20 and 30 of combustion chambers run through and be provided with air guide post 40; And on air guide post 40, offer air slot 41 and gas port 42; Air in the air-inlet cavity 10 are mixed with dimethyl ether fuel gas in the premix chamber 20, and the heat that utilizes the dimethyl ether fuel gas burning to produce carries out preheating to air-inlet cavity 10 interior air, improved the generation that the thermal efficiency has prevented red flame phenomenon simultaneously.

The above embodiment has only expressed a kind of embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with accompanying claims.
