Abstract
The utility model discloses an artificial gas burning device applied to a gas heater, which comprises a combustion chamber, a combustor in the combustion chamber, as well as an air baffle and a gas transmission device installed on the combustion chamber; the gas transmission device comprises an adapter device and a nozzle installed on the adapter device; the adapter device and an artificial gas pipeline are connected; the combustor comprises an ejector; the nozzle is stretched into the interior of the ejector. The artificial gas burning device applied to a gas heater has the advantages of not only strong firepower and high combustion efficiency, but without blocking or tempering.
Description
Technical field
The utility model relates to the gas heater technical field, relates to the artificial coal gas burner of a kind of gas heater in particular.
Background technology
Hydrogen content is more in the artificial coal gas, combustion potential is very fast, (liquefied gas 46, natural gas 40, artificial coal gas 7R combustion potential about 120), add working pressure and liquefied gas again, natural gas has very big difference (liquefied gas 2800Pa, natural gas 2000Pa, artificial coal gas 1000Pa), so artificial coal gas tempering occurs with respect to liquefied gas and natural gas are easier.Artificial coal gas gas instantaneous water heater product all is by reducing the fire hole area and control primary air to prevent its tempering at present.But the artificial coal gas composition is comparatively complicated, handles sordid coal gas for some, the burning back easily produce dust, how, impurity such as tar, if adopt the small fire hole burner, these impurity just are easy to fire hole is blocked, and gas can't normally be passed through, thereby cause tempering, accidents caused.For strengthening the serviceability of artificial coal gas product, must adopt big fire hole burner.Yet increase the fire hole area, the air capacity that combustion gas is entrainmented will increase, and very easily causes tempering for artificial coal gas.For this reason, must seek a kind of novel burning structure, both can solve dust and stop up, can prevent tempering again.
Summary of the invention
The utility model is exactly for the not enough and artificial coal gas burner of a kind of gas heater that provides of prior art is provided, and not only firepower is violent, efficiency of combustion is high, and do not stop up, not tempering.
The utility model is to adopt following technical scheme to realize above-mentioned purpose: the artificial coal gas burner of a kind of gas heater, comprise the burner in combustion chamber, the combustion chamber and be contained in air register and air delivery device on the combustion chamber, air delivery device includes piecing devices and is contained in nozzle on the piecing devices, piecing devices are connected with the artificial coal gas pipeline, it is characterized in that: burner includes injector, and nozzle stretches into this injector inside.
As further specifying of such scheme, described air register includes primary air baffle plate and auxiliary air baffle plate, the primary air baffle plate is for being provided with circular hole or oval-shaped platy structure, this primary air baffle plate is installed in burner injector front end, the auxiliary air baffle plate is the platy structure that is covered with aperture, and this auxiliary air baffle plate is installed in the bottom, combustion chamber.
Described primary air baffle plate is connected with injector front end air inlet, and the circular hole that nozzle passes on the primary air baffle plate stretches into injector inside.
Described burner tip is provided with fire hole, this fire hole be shaped as bar formula, cellular type, symmetrical expression, harmonica-type or flange.
Described fire hole width greater than 0.5mm less than 1.5mm.
Described combustion chamber is the cuboid shell-like structure, and the lower end is provided with opening, and the upper end is connected with heat exchanger cavities.
The beneficial effect that the utility model adopts above technical scheme to reach is:
Therefore 1. the utility model adopts big width fire hole, even what use is the artificial coal gas that is easy to generate various impurity, fire hole can be not blocked yet, and it is also very convenient to clear up.
2. the utility model adopts the nozzle of lengthening, reaches the injector inside of burner always, has strengthened the ejector capacity of nozzle, prevents that effectively tempering phenomenon from taking place.
3. the utility model is provided with primary air baffle plate and auxiliary air baffle plate,, reduces the auxiliary air amount reducing the heat that excess air is taken away by the auxiliary air baffle plate, thereby improves water-heater efficiency optimizing burning by primary air baffle controls primary air amount.
