Abstract
A burner for a gas water heater comprises a burner assembly and an air distributing device. The burner assembly comprises air guide tubes and a plurality of burners with burning fire holes. A gap is reserved between two distributing plates of the air distributing device. The upper ends of the burner are inserted into the bottom of a cylinder base of the air distributing device and penetrate through the gap between the two distributing plates. The lower ends of the burners are located below the two distributing plates which are attached to the lateral sides of the burners. Secondary air holes are matched with the burning fire holes arranged inside the base. Accordingly, the secondary air is directly supplied at the positions close to the burning fire holes, and the distribution of the secondary air is directly controlled. During burning of the gas, resultant of the gas and the secondary air which is enough but not surplus is burnt completely after the reaction between the gas and a first air in the process of gas burning. The total air coefficient of the gas burning can be reduced properly to realize complete burning, thereby improving heat efficiency of the heater.

In the fuel gas buring process, the employed air capacity of Actual combustion, the ratio with the required air capacity of chemical reaction completing combustion is called air coefficient, corresponding primary air ratio and the total air coefficient of being divided into.For the combustion gas tool, under the prerequisite that guarantees combustion gas completing combustion, total air coefficient is low more, just means that under the same gas quantity situation, combustion gas tool discharged flue gas amount is few more, and the combustion gas tool thermal efficiency is high more.
In the existing gas heater, generally adopt the overheavy firing mode: a burner shell with holes is arranged, a plurality of burners are surrounded, the perforate gross area on the burner shell, can control in the burner, with the primary air ratio of combustion gas mixing, simultaneously, perforated area on the burner shell and position, can control combustion system SAS Secondary Air Supply amount and with the coupling of fuel gas buring flame.
From practical situations, this structure exists certain not enough, and in the fuel gas buring process, auxiliary air and combustion gas coupling are undesirable, thereby can only strengthen total air coefficient, could realize the completing combustion of combustion gas, but so just reduce combustion gas heat energy utilization rate.
At present, adopt both at home and abroad in the gas heater product of air suspended type, under its peak load in the flue gas total air coefficient generally about 2, have in addition higher, far above general industry burner level, the product thermal efficiency promoted very big influence.From the situation of product test, exist combustion gas to mix inhomogeneous situation with air in the flue gas, for guaranteeing completing combustion, can only adopt overall excessive air capacity, guarantee the completing combustion of combustion gas.
Summary of the invention
The purpose of this utility model is: a kind of gas heater burner is provided, and it can guarantee that the SAS Secondary Air Supply amount reaches and the coupling of fuel gas buring flame, reduces the total air coefficient of fuel gas buring, realizes completing combustion, improves the water heater thermal efficiency.
The utility model is achieved in that a kind of gas heater burner, comprises burner assembly, and described burner assembly comprises the burner and the wireway of a plurality of burning fire holes of some tool bands, and is gapped between adjacent two burners; Its special character is: also comprise an air distribution device,
Described air distribution device comprises cylindrical base, the distribution plate of upper and lower opening and is arranged on auxiliary air hole on the distribution plate;
Described cylindrical base is made of longwell plate and shortwall plate, and described distribution plate is along the length direction setting of longwell plate, fixedlys connected with the shortwall plate in the two ends of distribution plate; Gapped between adjacent two distribution plates, the distribution plate of both sides and longwell plate are fitted;
Two gaps between the distribution plate are inserted, passed in the upper end of described burner from the bottom of cylindrical base, the burner lower end is positioned at the distribution plate below, fit in distribution plate and burner side, the auxiliary air hole cooperates with the burning fire hole, and the burner combustion fire hole is positioned at base.
Described a kind of gas heater burner, its special character is: have the baffle plate that is positioned at its both sides, baffle plate to be positioned on the upper surface or lower surface of distribution plate on the described distribution plate;
Fit in baffle plate and burner side.
Described a kind of gas heater burner, its special character is: the plane, auxiliary air dispensing orifice place on the described distribution plate is lower than the plane at burning fire hole place.
Described a kind of gas heater burner, its special character is: having the baffle plate that is positioned at its both sides, baffle plate to be positioned on the lower surface of distribution plate on the described distribution plate, fits in baffle plate and burner side; Plane, auxiliary air dispensing orifice place on the described distribution plate is concordant with the plane at burning fire hole place.
Described a kind of gas heater burner, its special character is: having the baffle plate that is positioned at its both sides, baffle plate to be positioned on the lower surface of distribution plate on the described distribution plate, fits in baffle plate and burner side; Plane, auxiliary air dispensing orifice place on the described distribution plate is higher than the plane at burning fire hole place.
A kind of gas heater burner of the utility model, owing to adopt such structure, the setting of air distribution device, auxiliary air is direct method of supplying near the burning fire hole, the directly distribution of auxiliary air in the control fuel gas buring process, make in the fuel gas buring process, after combustion gas and the primary air reaction, its product and capacity but not unnecessary auxiliary air carries out completing combustion, so just can suitably reduce the total air coefficient of fuel gas buring, realize completing combustion, thereby improve the water heater thermal efficiency.
