Abstract
A novel gas combustion device is provided, which consists of a thermal insulation layer, a combustion-supporting air inlet, a hot gas inlet, a gas spiral slice, a central combustion-supporting blast pipe, a combustor nozzle, a fixed flange, a combustion-supporting air spiral slice and a main body. The thermal insulation layer is positioned outside the main body; the combustion-supporting air inlet and the hot gas inlet are connected with the upper section of the thermal insulation layer; the combustor nozzle is connected with the front section of the utility model; the fixed flange is connected with the external section of the utility model; the central combustion-supporting blast pipe is arranged at the central section of the utility model; the gas spiral slice and the combustion-supporting spiral slice are connected with the front section of the utility model. The utility model adopts the mixing proportion combustion method, that is, the gas and combustion-supporting air finish proportioned pre-mixing in the combustion device or at the nozzle and then the nozzle injects the mixed gas into the furnace for combustion. Therefore, the utility model, which resolves the problem related to the velocity, pressure and combustion efficiency of gas, ensures sufficient combustion of gas, enhances the power output ratio of boiler and reduces the emission indicator of flue, is suitable for on-site promotion and application.
Description
Technical field:
The utility model relates to a kind of oil thermal recovery and annotates the burning heating gas boiler plant that uses in the vapour production, particularly novel combustion heating gas burner.
Background technology:
The oil thermal recovery injection boiler changes the burning heating gas by original burn crude at present, because heating gas temperature in entering the burner process reduces and easily forms tar, time has been grown burner has been stopped up, the coal gas of burner and the proportioning of wind are unreasonable, it is insufficient that heating gas is burnt in combustion process, not only waste a large amount of coals, also environment has been produced certain influence.
Summary of the invention:
The purpose of this utility model is to provide novel combustion heating gas burner.This utility model solves gas speed, gas pressure and the burning quality of heating gas in combustion process, and heating gas is fully burnt, and has improved the power rate that of boiler, reduces the fume emission index.
The purpose of this utility model is to realize like this, form by heat-insulation layer, combustion air import, heating gas import, coal gas blade, the combustion-supporting airduct in center, burner nozzle, mounting flange, combustion air blade, body, in body exterior heat-insulation layer is arranged, its top is connected to combustion air import, heating gas import, its front portion is connected to burner nozzle, external mounting flange, centre have the combustion-supporting airduct in center, and its front portion is connected to coal gas blade, combustion air blade successively.
Operation principle: the heating gas burner is the characteristics design according to heating gas: its gas passage is only established 4 guide plates, the angle of guide plate is not more than 15 °, coal gas is by burner the time, resistance is little, air-flow is unobstructed, improved the operating efficiency of gas furnace greatly, but burner continuous operations 3-5 month need not clear up.
The utility model has heat-insulation layer owing to having adopted in body exterior, its top is connected to combustion air import, heating gas import, its front portion is connected to burner nozzle, external mounting flange, there is the combustion-supporting airduct in center the centre, and its front portion is connected to coal gas blade, combustion air blade successively, and this burner adopts the mixed proportion combustion method, be coal gas and combustion air in burner or spout place completed percentage premix, spray into the stove internal combustion by the reducing burner then.The advantage of premix burner is coefficient of excess air little (being generally 1.03-1.05), and the flame intensity height can improve gas injection stove gas production; Easily igniting is regulated than little.This utility model solves gas speed, gas pressure and the burning quality of heating gas in combustion process, and heating gas is fully burnt, and has improved the power rate that of boiler, reduces the fume emission index, is well suited for field popularization application.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a left view of the present utility model;
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2 the utility model is described further.
By Fig. 1, Fig. 2 as can be seen, the utility model is made up of heat-insulation layer 1, combustion air import 2, heating gas import 3, coal gas blade 4, the combustion-supporting airduct 5 in center, burner nozzle 6, mounting flange 7, combustion air blade 8, body 9, in body 9 outsides heat-insulation layer 1 is arranged, its top is connected to combustion air import 2, heating gas import 3, its front portion is connected to burner nozzle 6, external mounting flange 7, centre have the combustion-supporting airduct 5 in center, and its front portion is connected to coal gas blade 4, combustion air blade 8 successively.
Heating gas burner and cooled coal gas, combustion of natural gas device have very big difference, and cooled coal gas, neat gas burner combustion medium are less demanding to burning condition, and heating gas contains a large amount of mist (H owing to do not have through purified treatment in the coal gas
2S, CO
2, gases such as steam), a large amount of dust is arranged simultaneously, coal tar, particularly coal tar easily produce and condense when being sent to low temperature environment, by the burner guide plate time, it is just attached on the guide plate, and is big more as the guide plate angle, adhere to seriously more, because coal tar has certain viscosity after condensing, coal gas has a large amount of dust, by guide plate the time, a large amount of dust are attracted on the guide plate, and the time one is long, and the part gas passage is blocked.Cause burner to stop up the blowing out accident.
The heating gas burner is the characteristics design according to heating gas: its gas passage is only established 4 guide plates, the angle of guide plate is not more than 15 °, coal gas is by burner the time, resistance is little, air-flow is unobstructed, improved the operating efficiency of gas furnace greatly, but burner continuous operations 3-5 month need not clear up.
This burner adopts mixed proportion combustion method, and promptly coal gas and combustion air spray into the stove internal combustion by the reducing burner in burner or spout place completed percentage premix then.The advantage of premix burner is coefficient of excess air little (being generally 1.03-1.05), and the flame intensity height can improve gas injection stove gas production; Easily igniting is regulated than little.
