Description
[technical field]
The utility model relates to a kind of burner, and in particular, the utility model relates to the high energy-saving combustion furnace of a kind of dimethyl ether.
[background technology]
Along with China's rapid development of economy, China has become energy-consuming big country, because the price of international energy that constantly rises and the targeted energy strategy target of countries in the world have consisted of the factor that has a strong impact on Chinese energy safety.The oil-poor many coals of China, the use amount of coal is more than 60% in the primary energy, and the direct burning of coal is used and will be increased CO2 emission, the deterioration of aggravation global climate environment.And countries in the world are day by day strong to the requirement of environmental protection and sustainable development, the essential renewable alternative new forms of energy of seeking environmental protection.Dimethyl ether is cheap with gas price as name, and burning is clean, the gas cylinder noresidue, and the apparatus such as pot kettle are without black smoke and fouling, and emission is carbon dioxide and water, and the discharging carbon dioxide is lower than oil liquefied gas, is the name combustion gas of the material benefit of very environmental protection.Make city gas with dimethyl ether, carried out preliminary research with on probation, for certain basis has been laid in the practical application of dimethyl ether.But because dimethyl ether self contains oxygen atom, cause the difference of its combustion system, gaseous-pressure, mixed gas mode, air intake mode etc. and other combustion gas.At equipment and technical elements, substitute existing combustion gas with dimethyl ether, it is to be solved that large-scale application also has many engineering technology problems to have in civil area.From the situation of present market, do not have the combustion furnace of dimethyl ether fuel gas special use, use on a small quantity dimethyl ether fuel gas to make fuel, also be that the kitchen range with existing other combustion gas use, exist burning insufficient, take off fire, the phenomenon such as misfire.For effectively utilizing dimethyl ether fuel gas oxygen-enriched combusting, high, the flame combustion temperature high of premix calorific value, the high energy-saving combustion furnace of special development DME combustion.
In sum, at dimethyl ether as a kind of novel gas, although and liquefied gas, kerosene have its similarity, but because the characteristic such as the oxygen demand of its burning, vaporization rate, gaseous-pressure and liquefied gas and kerosene etc. have difference, want dimethyl ether is applied to the restaurant as a kind of novel combustion domestic gas, just must design the combustion furnace that is fit to DME combustion according to the characteristic of dimethyl ether.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of combustion furnace of suitable DME combustion is provided, and this combustion furnace can improve the efficiency of combustion of dimethyl ether so that DME combustion is abundant, is a kind of high energy-conservation combustion furnace.
The technical solution of the utility model is achieved in that it comprises a vaporizer, have a plurality of burners on the described vaporizer, its improvements are: the decomposition heat-conducting plate that is provided with an annular on the described vaporizer, this decomposition heat-conducting plate outer ring is wound with a spiral gasification tube, described vaporizer also same fuel-air mixing duct connects, one end of above-mentioned spiral gasification tube passes in the fuel-air mixing duct, and the other end is connecting a control valve;
In the said structure, be provided with an igniter in the described fuel-air mixing duct;
In the said structure, the part of the decomposition heat-conducting plate of described annular middle part hollow is the combustion chamber;
In the said structure, described vaporizer middle part is set to a through hole, and this through hole is the combustion air entrance;
In the said structure, be provided with a plurality of burners around the combustion air entrance of described vaporizer;
In the said structure, described spiral gasification tube is welded on and decomposes the heat-conducting plate outer surface.
The beneficial effects of the utility model are: the utility model is by arranging the decomposition heat-conducting plate of annular at vaporizer, decompose the heat-conducting plate outside and welding spiral gasification tube, one end of spiral gasification tube is connected to the fuel-air mixing duct of vaporizer, the other end is connecting a control valve, this end is used for passing into gas of dimethyl ether, design by this kind structure, when dimethyl ether burns at the burner of vaporizer, heat by spiral gasification tube first, so that DME combustion is abundant, flame temperature is high, given full play to the characteristics of dimethyl ether fuel gas, and this combustion furnace saved the consumption of dimethyl ether greatly, for the pressure of alleviating city gas, improve China's energy resource structure, have irreplaceable effect.
[description of drawings]
Fig. 1 is schematic diagram of the present utility model.
[specific embodiment]
The utility model will be further described below in conjunction with drawings and Examples.
With reference to shown in Figure 1, the utility model has disclosed the high energy-saving combustion furnace of a kind of dimethyl ether, it comprises vaporizer 1, have a plurality of burners 2 on the vaporizer 1, dimethyl ether sends spurting flame by burner 2, be provided with the decomposition heat-conducting plate 3 of an annular on the vaporizer 1, these decomposition heat-conducting plate 3 outer rings are wound with a spiral gasification tube 4, and spiral gasification tube 4 is welded on the outer surface that decomposes heat-conducting plate 3; Above-mentioned vaporizer 1 also same fuel-air mixing duct 5 connects, and an end of spiral gasification tube 4 is arranged in the fuel-air mixing duct 5, and the other end is connecting a control valve 6, and this end is used for passing into gas of dimethyl ether; Also be provided with an igniter 7 in the above-mentioned fuel-air mixing duct 5.
