Abstract
The utility model relates to a combustor using gas fuel and solves the disadvantages that the known combustor using gas fuel has insufficient mixing of air and gas, low firepower and low thermal efficiency. The technical field includes that: a premixing chamber is fabricated, an air inlet is arranged on one end of the premixing chamber, the other end is provided with a combustion nozzle, cross section area of the premixing chamber gradually decreases from the air inlet end to the combustion nozzle direction, a gas distribution chamber is arranged outside the premixing chamber, a gas inlet is arranged on the gas distribution chamber, a plurality of gas distribution holes connected with the gas distribution chamber are arranged close to the air inlet of the premixing chamber. The combustor is applicable to various cooking stoves.
Description
Technical field
The utility model relates to a kind of burner, particularly a kind of burner of using gases fuel.
Background technology
Advantages such as gaseous fuels such as natural gas, liquefied gas, biogas have combustion process is not had smoke contamination, and discharge of noxious gases is few.The burner ubiquity air and the combustion gas mixing of present known using gases fuel are insufficient, and burning velocity is slow, and temperature is low, and the problem that firepower is less than normal for a lot of use occasions, usually can't be used because firepower is not enough.The lower flame temperature heat that generates that is unfavorable for burning is delivered to heating object, and the thermal efficiency is difficult to improve.
Summary of the invention
The technical problem that solves:
Insufficient in order to solve the burner air and the combustion gas mixing that have known using gases fuel now, firepower is little, the shortcoming that the thermal efficiency is low, the utility model provides a kind of burner, this burner can fully mix air and combustion gas fast, make the conflagration of combustion gas energy, improve flame temperature, firepower is big, the thermal efficiency is high.
Technical scheme:
Make a premixer, one end is provided with air intlet in the premixer, other end look is provided with burner noz(zle), the premixer diminishes to burner noz(zle) direction sectional area gradually from the air intlet end, gas distributing chamber is set outside the premixer, fuel gas inlet is set in the gas distributing chamber, a plurality of air distribution holes that link to each other with gas distributing chamber are arranged near premixer's air intlet.
When using this burner, combustion gas enters gas distributing chamber from fuel gas inlet, enters the premixer by air distribution hole then, mixes with the air that enters from air intlet, because air distribution hole has a plurality ofly, combustion gas and air mix simultaneously at each air distribution hole place.It is that because sectional area diminishes gradually, linear velocity constantly increases, and can quicken mixed process that mist moves to gas nozzle in the premixer.Air and combustion gas are being sprayed by burner noz(zle) after fully mixed and are burning outside nozzle, owing to mix, burning velocity is fast, and firepower is big, the flame temperature height.Cut with scissors high flame temperature and help heat and be delivered to heating object, improved the thermal efficiency.
Beneficial effect:
Air and combustion gas mixing are abundant fast, the flame temperature height, and firepower is big, thermal efficiency height.

Fig. 3 is the cutaway view of A-A line among speech Fig. 1.
The specific embodiment
Fig. 1 to Fig. 3 is the schematic diagram of an embodiment of the utility model.As shown in the figure, make a premixer 1,1 one ends are provided with air intlet 3 in the premixer, other end look is provided with burner noz(zle) 2, premixer 1 diminishes to burner noz(zle) 2 direction sectional areas gradually from air intlet 3 ends, outside the premixer 1 gas distributing chamber 5 is set, fuel gas inlet 4 is set in the gas distributing chamber 5, a plurality of air distribution holes 6 that link to each other with gas distributing chamber 5 are arranged near the air intlet in the premixer 13.
