Abstract
The invention discloses a fully premixed metal fiber burner for a gas water heater. The fully premixed metal fiber burner for the gas water heater comprises a cavity body and a burner, the top end of the cavity body is firmly connected with a gas mixing device, the gas mixing device is communicated with a gas inlet in the top end of the cavity body, a dispersion plate through which the mixed gas passes is firmly arranged on the bottom end of the cavity body, the burner is firmly connected with the lower side of the dispersion plate back on to the cavity body, and the burner is composed of at least two layers of metal nets connected with the inside of the cavity body; the size of the gas inlet is matched with the mixed gas flow rate, and the longitudinal central line of the gas inlet deviates from the longitudinal central line of the cavity body so as to distribute the mixed gas current more uniformly. By means of the fully premixed metal fiber burner for the gas water heater, the flame height is consistent, the burning state is stable, the CO and NOX output is effectively lowered, and the energy conservation and environment protection are realized.
Description
Technical field

Background technology
At present in gas heater technical field, full pre-mix condensing gas heater rely on the plurality of advantages such as its energy-conserving and environment-protective more and more accept by consumer, therefore the research of its critical component burner is also got more and more.But due to the difference of gas heater project organization, especially air inlet position is different, thus cause the inconsistent flame that causes of combustion gas air pressure uneven, easily produce CO and NO
x, be unfavorable for environmental protection.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides the full premix metal fiber burner of a kind of gas heater, this burner structure is simple, and during work, even flame, fired state are stablized.
The present invention in order to the technical scheme solving its technical problem and adopt is: the full premix metal fiber burner of a kind of gas heater, comprise cavity and burner, the top of described cavity is located by connecting in a gas mixing device, and the air inlet on described gas mixing device and described cavity top end connects, on the bottom of described cavity, location is provided with a diffuser plate passed through for mist, described burner is located by connecting in the downside of described diffuser plate described cavity dorsad, and the wire netting that described burner is communicated by least two-layer and described inside cavity forms; Size and the mixed gas flow size of described air inlet match, and the longitudinal centre line of the longitudinal centre line of described air inlet and described cavity deviates.
As a further improvement on the present invention, described cavity comprises two to the side plate of corresponding setting and the top board that is connected with this two pairs of side plate tops, and described air inlet locating open is located on described top board.
As a further improvement on the present invention, described gas mixing device is fixedly connected on the lateral surface of described cavity top board by several bolts.
As a further improvement on the present invention, also be provided with the balance plate that stainless steel is made, described balance plate evenly offers several holes, described balance plate location to be arranged in described cavity and near the position of described air inlet, and described balance plate be able to cover described air inlet towards the projection of described cavity top board.
As a further improvement on the present invention, with user to for benchmark, the arc-shaped concave structure low centered by described diffuser plate, outer ledge is high, and several waist-shaped holes are evenly offered on described diffuser plate.
As a further improvement on the present invention, described burner is made up of double layer of metal net, this double layer of metal is descended parallel on the net and is welded as a whole, the wire netting being wherein positioned at lower floor is the metal web that ferrum-chromium-aluminum material is made, another wire netting being positioned at upper strata is stainless steel metal silk screen, and the stainless steel metal silk screen being positioned at upper strata is welded on described diffuser plate.
The invention has the beneficial effects as follows: by the air inlet be opened on cavity top board being deviated from the longitudinal centre line of cavity, can better make mixed airflow be evenly distributed, guaranteeing to make that flame height is consistent, fired state is stablized, significantly reduce CO and NO
xgeneration, energy-conserving and environment-protective.
