Abstract
The utility model relates to a gas burner, comprising a casing, a gas inlet pipe and an air inlet valve. The utility model is characterized in that a round pipe is arranged in the casing; a rectifier is sheathed on the round pipe; annular space surrounded by the casing and the round pipe is divided into a front mixing chamber and a rear mixing chamber by the rectifier; the air inlet valve is communicated with the front mixing chamber; the gas inlet pipe is communicated with a gas distributing chamber arranged in the front mixing chamber; an explosion-proof hole is arranged on the casing; a turnable explosion-proof plate sheathed on the casing is arranged by abutting the explosion-proof hole; the tail of the casing is connected with a screw nail or a pin of a spray head cover. The burner can cause the gas and the air to be fully mixed to enhance the combustion efficiency, and the gas burner has the safe explosion-proof performance.
Description
The utility model relates to a kind of gas burner, and being specially adapted to natural gas, coal gas is the various boilers or the heating furnace of fuel.
Be that the burner that uses in the boiler of fuel or the heating furnace mainly is made up of backboard 1, nozzles body 2, combustion gas distributor chamber 3, Gas Pipe 4, burner port 5, inlet valve 6 at present, as shown in Figure 1 with natural gas, coal gas.Mainly there is following shortcoming in this burner: 1. adopt gravity-flow ventilation, air feed, combustion gas and air can not fully mix, thereby efficiency of combustion is low, and nozzles are easily tied carbon, and waste energy, contaminated environment; 2. there is not explosion-protection equipment, poor safety performance.
The purpose of this utility model is to overcome shortcoming of the prior art, provides a kind of combustion gas is fully mixed with air, efficiency of combustion height, and the gas burner with explosion-proof performance.
The purpose of this utility model is achieved in that gas burner comprises housing, gas inlet pipe and air inlet door, its characteristics are: enclosure interior is equipped with a pipe, be with rectifier on the pipe, mixing chamber and back mixing chamber before rectifier is divided into the annular space that housing and pipe surrounded, air inlet Men Yuqian mixing chamber communicates, gas inlet pipe be located at before combustion gas distributor chamber in the mixing chamber communicate, have explosionproof hole on the housing, near what live explosionproof hole is to be enclosed within on the housing and rotating bursting diaphragm, and the housing afterbody is connected with nozzle cap screw or pin.
A standby gas inlet pipe also is equipped with in the inside of the pipe of adorning in the said burner housing, and standby gas inlet pipe is equipped with the injection type shower nozzle near the body of heater end, and standby gas inlet pipe communicates with gas inlet pipe.
The utility model utilizes rectifier that burner is divided into two chambers, and combustion gas can fully be mixed with air, sprays through shower nozzle again, reach good ratio of combustion, simultaneously on housing, have explosionproof hole, and on housing, put bursting diaphragm, thereby make burner safer, more reliable.
Accompanying drawing 1 is the structural representation of prior art burner;
Accompanying drawing 2 is a structural representation of the present utility model.
Be further described below in conjunction with 2 pairs of the utility model of accompanying drawing:
Among the figure: the 7-gas inlet pipe; The 8-pipe; The 9-housing; 10-combustion gas distributor chamber; Mixing chamber before the 11-; The 12-rectifier; Mixing chamber behind the 13-; The 14-bursting diaphragm; The 15-explosionproof hole; The 16-nozzle cap; 17-injection type shower nozzle; The standby gas inlet pipe of 18-; 19-air inlet door; 20-gas inlet pipe valve; The valve of the standby gas inlet pipe of 21-; The 22-gas pipeline.
Burner as shown in Figure 2, comprise housing 9, air inlet door 19, gas inlet pipe 7, air inlet door 19 is contained in housing 9 front portions, air inlet door 19 is by the air blast forced air supply, be provided with a pipe 8 at housing 9 middle parts, be with rectifier 12 on the pipe 8, rectifier 12 is made up of many small tubes, and the middle part is hollow.Mixing chamber 11 and back mixing chamber 13 two parts before the annular space that rectifier 12 is surrounded pipe 8 and housing 9 is divided into, preceding mixing chamber 11 communicates with air inlet door 19, valve 20 is housed on the gas inlet pipe 7 to communicate with gas pipeline 22, gas inlet pipe 7 be located at before combustion gas distributor chamber 10 in the mixing chamber 11 communicate, housing 9 afterbodys are connected by screw or pin with nozzle cap 16.Standby gas inlet pipe 18 is equipped with in pipe 8 inside, valve 21 is housed on the standby gas inlet pipe 18 to communicate with gas pipeline 22, standby gas inlet pipe 18 is connected with gas inlet pipe 7, injection type shower nozzle 17 is equipped with in the front portion of standby gas inlet pipe 18, the stand-by provision the when gas combustion apparatus in the pipe 8 is power failure.The part that contacts with body of heater on the housing 9 has explosionproof hole 15, near what live explosionproof hole 15 is to be enclosed within on the housing 9 and rotating bursting diaphragm 14, explosionproof hole 15 mainly contains two effects with bursting diaphragm 14: the one, when body of heater meets accident, the gases at high pressure that produce can play safety, protective effect from releasing here; The 2nd, when having a power failure, can be from entering the injection type shower nozzle of lighting in the pipe 8 17 here, and can regulate the size of bursting diaphragm 14 control air intakes.
When burner uses, open the valve 20 of gas inlet pipe 7, combustion gas enters combustion gas distributor chamber 10 by gas inlet pipe 7 and enters preceding mixing chamber 11 again, in preceding mixing chamber 11 with air inlet door 19 in the air forcing to send into mix for the first time, again through rectifier 12, mist is evenly distributed, in the mixing chamber 13 of back, mix once more again, spray into body of heater by the spray orifice on the nozzle cap 16, spray orifice on the nozzle cap 16 has different angles, can produce eddy flow in stove like this when shower nozzle sprays into body of heater, combustion gas can fully be burnt, efficiency of combustion improves greatly.During power failure, can open the valve 21 of standby gas inlet pipe 18, light the injection type shower nozzle 17 in the pipe 8 from explosionproof hole 15, regulate bursting diaphragm 14 again, the size of control air-supply is made general burner and is used.
