Abstract

The utility model discloses a novel burner, which comprises a front support frame, a back support frame and a plurality of vertical fire row sheets, wherein the vertical fire row sheets are fixedly arranged between the front support frame and the back support frame, each fire row sheet comprises a plurality of fire holes and a combustible gas-air mixing passage, the fire holes are arranged on the top of each fire row sheet and extend in the longitudinal direction, the combustible gas-air mixing passage is formed on a body and is provided with a gas inlet and a Venturi tube part positioned at the upstream of the mixed gas passage, and the Venturi tube part comprises an inlet contraction section, a cylindrical throat part and a conical diffusion section in sequential connection. Compared with the prior art, the novel burner has the advantages that the cross section area of the air inlet and the cross section area of the throat part are set through the Venturi tube part, and combustible gas and air can be fully mixed, so the burning efficiency of the burner is improved, and the emission of oxycarbides and nitric oxides in smoke gas is reduced.

Description

A kind of novel burner
[technical field]
The utility model relates to a kind of burner, relates in particular to the novel burner that a kind of gas heater or gas fired-boiler are used.
[background technology]
Gas and hot water equipment is such as the burner, the heat exchanger that usually are provided with in gas heater or the gas fired-boiler and hold burner and the combustion chamber of heat exchanger.Burner often includes the some fire row sheets that are arranged side by side, each fire row sheet has the hybrid channel of combustion gas-air, can be within it combustion gas and air mixed and pass to the fire hole that is positioned at fire row sheet top with at combustion chamber internal combustion and producing heat, but the water in the heat reheat heat exchanger that generates, thereby heated water can be used for drinking, bathing or heating etc.
In the existing burner, the mixing of combustion gas and air is also insufficient, thereby not fully burning of combustion gas reduced efficiency of combustion, and because imperfect combustion produces a large amount of waste gas.
[utility model content]
The utility model is in order to solve above-mentioned deficiency, a kind of novel burner to be provided.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of novel burner, comprise fore-stock, after-poppet and be fixed on some upright fire row sheet between the front and back support, each fire row sheet comprises the some fire holes along the lengthwise extension that are located at its top, and be formed on combustion gas on the body-air hybrid channel, described combustion gas-air hybrid channel has air inlet and is positioned at the Venturi tube part of mixed-gas channel upstream, and Venturi tube partly comprises entrance contraction section, cylindrical shape throat and the conical diffuser that connects successively.
The ratio of the sectional area of described air inlet and the sectional area of throat is positioned at 2: 1~between 6: 1, is preferably 4: 1.
The utility model advantage compared with prior art is: in Venturi tube of the present utility model part to the air inlet sectional area with the throat section is long-pending arranges, combustion gas and air can fully be mixed, thereby improve the efficiency of combustion of burner, the discharging of oxycarbide and nitrogen oxide in the reduction flue gas.
[description of drawings]
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the structural representation of the utility model Venturi tube part.
In the accompanying drawing, the 1-fore-stock; The 2-after-poppet; 3-fire row sheet; The 4-fire hole; 5-combustion gas-air hybrid channel; The 6-air inlet; 7-Venturi tube part; The 71-contraction section; 72-throat; The 73-diffuser.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in further detail:
Such as Fig. 1, shown in 2, a kind of novel burner, comprise fore-stock 1, after-poppet 2 and be fixed on some upright fire row sheet 3 between the front and back support, each fire row sheet 3 comprises the some fire holes 4 along the lengthwise extension that are located at its top, and be formed on combustion gas on the body-air hybrid channel 5, combustion gas-air hybrid channel 5 is used for the combustion gas of fuel gas supply equipment (not shown) supply and primary air are mixed generating gas-air mixture in the ratio of setting, and pass to fire hole 4 for burning, described combustion gas-air hybrid channel 5 has air inlet 6 and is positioned at the Venturi tube part 7 of combustion gas-5 upstreams, air hybrid channel, Venturi tube part 7 comprises the entrance contraction section 71 that connects successively, cylindrical shape throat 72 and conical diffuser 73, combustion gas and air suck at air inlet 6, converge at contraction section 71, mist obtains maximal rate in throat 72, and fully mixes at diffuser 73.In the present embodiment, air inlet 6 is the entrance of contraction section 71, and the ratio of the sectional area of the sectional area of air inlet 6 and throat 72 is positioned at 2: 1~between 6: 1, is preferably 4: 1.
It should be noted that at last: above-described embodiment only is for the utility model example clearly is described; and be not restriction to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here need not also can't give all embodiments exhaustive, and the apparent variation of being amplified out thus or the change still be among the protection domain of the present utility model.
