Abstract
The invention relates to an industrial gas burner. The industrial gas burner comprises a cylindrical housing, and a gas guide pipe arranged in the housing, wherein a burning head is arranged in the front end of the housing and adjustably sleeved on the gas guide pipe; a swirler is arranged at the front end of the housing, and an air guide blade inclined to an axis of the housing is fixed onto the swirler; a front cover is also arranged at the front end of the housing, with the front end contracted inwards to form a circular opening, and the inside diameter of the opening is more than the outside diameter of the burning head. According to the industrial gas burner, the swirler is arranged outside the burning head, which can further promote the gas burning during burning under gas, and moreover, the flame in burning can be spread to the outside by means of rotating through the swirler, therefore, the burning area of the flame is expanded. The front cover is arranged at the front end of the burning head, and the edges of the flame in burning are baffled by the front cover, thus, the edges are forcibly close to centre of the flame, and spewed out from the opening at the front cover, and the flame in burning is collected and extended, and the full burning is achieved, the emission of CO and NOx is reduced, and the stability of the flame is improved.
Description
Technical field
The invention belongs to gas combustion technical field, relate in particular to a kind of industrial gas burner.
Background technology
No matter the burning of which kind of combustion gas, all needs air-breathing, and the mixed proportion of combustion gas and air and mixability determine the burning degree of combustion gas.Fuel gas buring is more abundant, and the calorific value producing is also the highest, and the waste gas and the pernicious gas that after burning, produce are also minimum, thereby reaches the object of efficient, energy-conservation and environmental protection.
The stove and accessory of existing market, from aerodynamics angle, can be divided into two large series products, and a class is natural wind cooking stove, and a class is blowing-type cooking stove.And blowing-type cooking stove combustion mode is on the market rear mixing combustion mode, i.e., in the process that combustion gas is burnt in furnace chamber, synchronously mix with air, because combustion gas is difficult to fully mix with air immediately, thereby causes combustion gas fully to burn.Part is failed the combustion gas of burning, can from flue, discharge, thus cause the waste of the energy and the pollution of environment aspect.
Gaseous fuel belongs to hydrocarbon, and the present most burners particularly above burner of unit high-power (14MW) all adopt diffusion combustion mode (being that fuel does not mix with combustion air before burning).The inner local temperature of diffusion combustion flame is quite high, and air distribution is inhomogeneous, and in this case, hydrocarbon can decompose, and produces solid carbon black, even forms black smoke, reduces efficiency of combustion, and also produces in a large number CO and NOx.Burner rating is larger, and this phenomenon is just more serious.
In the prior art, some gas burners are provided with cyclone, and combustion air, after the burned flame sucking-off of the blade of cyclone, further promotes fuel gas buring on the one hand, Rotational diffusion can make flame combustion on the other hand time, the burning area of expansion flame.Existing cyclone operated by rotary motion is in combustion flame, and the cyclone technology that is arranged on flame outside needs to be further improved.
In addition, current gas stove, has inconvenience more than aspect automatic ignition; And aspect blowout protection, more have disappearance, there is potential safety hazard.
