Description

A kind of gas furnace

The utility model relates to the gas furnace of hotel and collective's dining room use.

At present, gas furnace that use hotel and collective dining room or gas-cooker be to keeping indoor cleaning, guarantees that the supply that food and drink is had a meal played very big effect.But the combustion gas of this present class gas furnace can not get burning fully and has wasted the energy, and igniting is inconvenient, and noise causes environmental pollution greatly during burning work.

The purpose of this utility model provides a kind of gas furnace, allows combustion gas fully burn and energy savings, and igniting is convenient, and noise is little.

Technical solution of the present utility model is on the basis of the shell that has the gas furnace of using in hotel and collective dining room now, burner hearth, gas inlet pipe, tolerance control valve, the utility model is fixed with burner at burner hearth bottom, there is blower fan to become eccentric position to be connected in the enclosure by airduct and burner, burner ejiction opening direction is the angle of its cylindrical entrance angle, gas inlet pipe is connected on airduct, and the burner below is fixed with igniter.

Above-described burner comprises a main ignition combustor, and encloses on the main ignition combustor on the main ignition combustor.

The utility model igniter includes igniter, the fixing electronic pulse ignition pin at igniter one side or two side places.

Burner ejiction opening direction of the present utility model is 45 degree of its cylindrical entrance angle.

The utility model is introduced blower fan and is produced pressure wind-force, in airduct, fully mix with the combustion gas that enters is enforceable in advance, the coefficient of excess air α adjusting of combustion gas is controlled between 1.2 to 1.5, approximate with the flameless burning principle, combustion gas after fully being pre-mixed enters burner by the airduct of eccentric position and just forms rotation wind, uniform aperture rotation sprays at a high speed through the combustion chamber again, reaches combustion gas and fully burns, the purpose that firepower is evenly concentrated, temperature is high.

The burner nozzle place is owing to force the effect of wind-force, the gas flow rate of ejection is very high, if spout is set to common making progress, can produce when then burning from the flame phenomenon, if the spout direction is perpendicular to changeing in the heart alignment, then because the flameless burning mode is very violent, the air in the time of can making combustion reaction produces vibration, sends very big noise.So the utility model burner nozzle direction is designed to the scalene cone of nearly 45 degree, violent and burning very completely that can be stable under the effect of enclosing on the burner can not produce noise.

Burner of the present utility model is in the place at the bottom of the burner hearth and below the bottom, so the burner lower end can be provided with the electronic pulse ignition system, at first produce electric spark firing point firearm at igniting pin place by electric pulse, the little fire of the igniter main ignition combustor that ignites again only needs gently once going by ignition switch ignition operation.And this traditional class cooking stove is because volume is big, and operated valve handle position and burner position are far away, and thermic load is big, so be provided with automatically, half-automatic ignition is all very difficult, adopts all generally that burning torch or a scrap of paper are manual lights a fire, and obviously is inconvenience and dangerous.But and also set-point firearm flame detecting, the flame-out protection of dying automatically of the utility model, make ignition process become safer.

Operation sequence of the present utility model is, opens source of the gas master switch, fan power switch earlier, opens the air quantity valve and blows out waste gas in the burner hearth, closes the air quantity valve again.Press ignition switch then, at this moment power supply becomes 3V through transformation 220V, make the electronic circuit controller produce the delay pulse high-tension electricity, between igniting pin and igniter, produce the Pulse Electric spark, open by the magnetic valve of electronic circuit controller control simultaneously, combustion gas is brought the part air via magnetic valve into from the nozzle ejection and is pre-mixed the back in igniter inside from the ejection of igniter spout, and is lighted by electric spark.After igniter was lighted, trace was opened air quantity valve and main internal heat metered valve, and main fire burns is promptly lighted, and at this moment closes ignition switch.According to required firepower size, regulate the gentle metered valve of air quantity valve simultaneously, air quantity is large-minded, and firepower is just big, otherwise then little.Close gas check valve, air quantity valve, blower fan, flame-out when having worked.

The utility model has the advantages that combustion gas is fully burned, energy savings, igniting is convenient, and noise is little.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Fig. 1 organigram of the present utility model.

According to shown in Figure 1, the utility model is at the shell that has the gas furnace of using in hotel or collective dining room now, burner hearth 1, gas inlet pipe 12, on the basis of tolerance control valve 8, the utility model is fixed with burner in burner hearth 1 bottom, there is blower fan 9 to become eccentric position to be connected in the enclosure by airduct 6 and burner, burner ejiction opening direction is 45 degree of its cylindrical entrance angle, and gas inlet pipe 12 is connected on airduct 6, and the burner below is fixed with igniter.Burner comprises a main ignition combustor 3, and encloses 2 on the main ignition combustor on the main ignition combustor 3, and igniter includes igniter 5, and 5 two side places are fixed with electronic pulse ignition pin 4 at igniter.With igniting pin 4 links to each other an electronic pulse controller 7 arranged, control valve 8 with tolerance has volume control damper 10 on airduct 6 on gas inlet pipe 12, and what link to each other with igniter 5 and gas inlet pipe 12 has a magnetic valve 11.
