Description
Technical field
The present invention relates to a kind of burner apparatus, particularly is a kind of matching used gas burner of industry, civil boiler and industrial furnace that is used for.
Background technology
Coal, fuel oil are well-known common fuels.For pollute, the consideration of aspect such as occluding device whether easily, a large amount of fuel oils that use such as present various industry, civil boiler and industrial furnace act as a fuel, such as being used in aspects such as the roasting bag of steel-making, baker, heating.But easy to be acquired from cost angle and resource, coal obviously has suitable advantage, and therefore, it all is a focus of research and development for a long time that exploitation replaces the technology of fuel oil with coal.But because the combustibility of raw coal is not as fuel oil, and the reasons such as pollution of the discharge of cinder, coal smoke, it is very difficult causing directly adopting raw coal to replace fuel oil.At present, the feasible way of replace oil with coal is to prepare coal gas with coal to replace fuel oil under the prerequisite of not changing existing boiler, stove.Even if but replace fuel oil with coal gas, because the difference on coal gas and the fuel performance, the burner of existing boiler, stove etc. also must be redesigned.Burner is requisite visual plants such as these industry, civil boiler and industrial furnace.Chinese patent or Chinese patent application CN02125836.8, CN02203114.6 and CN200620034098.3 etc. have promptly introduced some and have been applicable to the burner of coal gas.The basic structure of these burners is substantially: mainly by the air hose that is provided with the mixing chamber spout, be threaded onto gas pipe, igniter and burning in the air hose and chew brick and constitute.Though existing these burners have been obtained certain progress, need be overcome but still come with some shortcomings.The fuel oil of original burner is spray pattern usually when ejection, it between the fine drop discrete state, so it is good with the Air mixing degree, and coal gas integral body when the gas pipe mouth of pipe sprays is not easy to disperse, so it is and relatively poor relatively by the mixing between the air of the air hose of gas pipe periphery ejection, cause air-distribution uneven and to cause burning stable inadequately and burning is abundant inadequately, burn insufficiently can cause in the burner hearth easily the coking carbon deposit again and stop up burning and chew problems such as fire jetting hole.For solving coal gas and Air mixing problem, the gas pipe mouth of pipe of existing burner contracts usually in the air hose mouth of pipe, in the distance that contracts be approximately 10cm, so that coal gas has certain space to mix with air, thereby and adopt cyclone to make air swirl try hard to make air fully to mix usually with coal gas, but since the characteristics of air swirl to be peripheral flow velocity fast and the center flow velocity is slow, the effect on historical facts or anecdotes border is unsatisfactory.In addition, with respect to the oil burner before transforming, the flame of gas burner is shorter.Its reason is that fuel oil is a liquid, and proportion is bigger, thereby can spray far, and coal gas is light, and under same muzzle velocity condition, the distance of ejection is than fuel oil much shorter.And if elongate flame by increasing the coal gas spouting velocity, may cause from combustion instability phenomenons such as flames.So existing gas burner is difficult to be applicable to some occasion,, otherwise can have the zone of flame and the marked difference on the aphlogistic regional cured effect such as baker etc.
Summary of the invention
Technical problem to be solved by this invention is the present situation at prior art, provides a kind of gas-fired stable and sufficient high-efficiency thermal gas burner.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: high-efficiency thermal gas burner of the present invention, comprise that a gas pipe and is enclosed within the outer interior cover of gas pipe, space in the gas pipe is a gas chamber, and the space between interior cover and the gas pipe is the primary air chamber, the front end of gas chamber and primary air chamber is respectively equipped with gasburner and primary air outlet, the rear end of gas chamber and primary air chamber then is respectively equipped with gas entry and primary air inlet, the outside that it is characterized in that described interior cover also is with an overcoat, space between interior cover and the overcoat is the auxiliary air chamber, the rear end of auxiliary air chamber is provided with the auxiliary air inlet, and the front end of auxiliary air chamber is provided with the auxiliary air outlet.
The air-out direction of described auxiliary air outlet tilts towards the extended line direction of the center line of described gasburner.As for concrete angle of inclination, can adjust definite according to the pressure of the size of each part of burner, gas and required length of flame that reaches etc.
Be sealedly connected with the edge sealing of conical surface shape between the interior cover in described auxiliary air exit and the overcoat, edge sealing upper edge hoop offers a circle airflow hole, and the extended line of the extended line of the center line of airflow hole and the center line of described gasburner intersects, and described auxiliary air outlet promptly is made of these airflow holes.
The indoor air of described auxiliary air is a pressure-air.
Described gasburner is mutually concordant with described primary air outlet.Adopting under the situation of pressure-air as auxiliary air, because the promotion immixture of auxiliary air is arranged, so gasburner and primary air are exported the mixed effect that concordant setting not only can not influence air and coal gas, help preventing dispersing too early of coal gas and air Mixture on the contrary, so that wrapping up under the band effect of high-voltage secondary air, obtain the flame of concentrating and elongating.
Described gasburner is the taper throat structure.The taper throat structure of gasburner is provided with and is beneficial to the exit velocity that improves coal gas, flame is elongated, and the impurity such as tar in the gasburner are taken away.
Compared with prior art, have following advantage:
1, because the present invention has increased periphery auxiliary air supplementing structure, effectively improved air-distribution, made it more even, thereby gas-fired is more stable, the burning is more abundant, also make burner be not easy carbon deposit and obstruction gasburner; With respect to original fuel oil equipment, production cost can reduce and reaches more than 50%.
2, being obliquely installed of the air-out direction of auxiliary air outlet helps promoting fully mixing of air and coal gas more, particularly adopt under the situation of pressure-air at auxiliary air, promotion to mixed effect is particularly evident, and is particularly conducive to the flame elongation, makes firepower more powerful and concentrated.
