The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to transferring its specific embodiment of flame burner, structure, feature and effect thereof according to the coal gas that the utility model proposes, describe in detail as after.
See also Fig. 1, shown in Figure 2, the utility model coal gas is transferred flame burner, it mainly comprises: gas entry flange and tube connector 1, combustion air inlet flange and tube connector 2, combustion air one secondary air adjustor valve plate 3, burner block 4, control valve rotating shaft 5, regulating handle 6, burner main body 7;
Transfer the air intake place of flame burner to be provided with combustion air one secondary air adjustor valve plate 3 at the utility model coal gas, be used to regulate the ratio of wind of burner and secondary wind, the length of flame is changed; According to the deflection angle of different this valve plates of heating furnace width adjusting, make the air output of a secondary wind that the interlock variation take place, realize the adjusting of the length of flame.
Transfer flame burner to be described further below in conjunction with accompanying drawing to the utility model coal gas.
Above-mentioned coal gas transfers the burner main body 7 of flame burner for coal gas has flame burner nozzle, by changing the size of air premix amount in coal gas, changes coal gas and Air mixing time, makes coal gas mixed combustion by stages step by step, and therefore flame changed length.Burner block 4 is installed on the body of heater, and burner block plays the effect of smooth combustion and control flame direction.Combustion air inlet flange and tube connector 2 are connected with burner block 4 by ring flange and are fixed on the body of heater side wall, gas entry flange and tube connector 1 connect to form burner main body 7 by ring flange and combustion air inlet flange and tube connector 2, be provided with passage in coal gas tube connector and the air tube connector, make sky, coal gas enter burner block, in burner block and burner hearth internal combustion according to passage separately.
See also shown in Figure 3 again, transfer the combustion air inlet flange and tube connector 2 places of flame burner to be provided with a secondary air adjustor valve plate 3 at the utility model, coal gas, this adjusting valve plate 3 is to be connected with combustion air inlet flange and tube connector 2 by control valve rotating shaft 5, regulates valve plate 3 and can rotate around this control valve rotating shaft 5; The valve handle end of this adjusting valve plate 3 is provided with regulating handle 6, indicate the scale of length flame in the top of regulating handle 6, a side scale indicates long flame, and the opposite side scale indicates short-flame, be inserted with 1～3 angle graduation between the two, indicate the degree of deflection of regulating valve plate 3.The deflection angle that regulating handle 6 can be regulated control valve plate 3 according to the situation of different heating-furnace width links the air quantity of primary and secondary air, realizes the adjusting of the length of flame.
Under the state of the certain also smooth combustion of gas flow, when the regulating handle 6 that rotates a secondary air adjustor valve plate 3 makes wind side of adjusting valve plate 3 deflections, will reduce primary air flow, correspondingly increased secondary air flow, flame is elongated, and the deflection degree of valve plate is big more, and the length of flame is corresponding long more.Under the certain also smooth combustion state of gas flow, when the regulating handle 6 that rotates a secondary air adjustor valve plate 3 makes adjusting valve plate 3 deflection secondary wind sides, will reduce secondary air flow, correspondingly increased primary air flow, flame shortens, and the deflection degree of valve plate is big more, and the length of flame is corresponding short more.
It is progressively mixed combustion stage by stage that above-mentioned coal gas is transferred the coal gas of flame burner and combustion air, and [NOx] is low for formation of nitrogen oxides, has the advantage of energy-conserving and environment-protective.
The utility model coal gas transfers flame burner to be fit to the requirement of different furnace width, because the agent structure of burner is reasonable, on the basis of having realized completing combustion, coal gas is controllably hierarchically mixed stage by stage with air with combustion air, has realized progressively mixing.The length of flame that so promptly extended, it is even to make flame go up temperature along its length again, and gas-fired is thorough, thus it is even to reach fire box temperature, and then improve billet quality.
Coal gas is transferred flame burner simultaneously, also has the gas heating of use capacity adjustment than big, and the length of flame is adjustable, and [NOx] is low for formation of nitrogen oxides, the advantage of energy-conserving and environment-protective.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, foundation technical spirit of the present utility model is to above any simple modification that embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
