Description
Technical field
The utility model relates to a kind of firing equipment, particularly relates to a kind of heat accumulating type firing equipment.Belong to furnace apparatus technical field.
Background technology
Recuperative heater adopts heat-storage type fume residual heat recovering device, alternately switch air or gaseous fuel and flue gas, make it to flow through heat storage, the sensible heat of high-temperature flue gas can be reclaimed to the full extent, and can by combustion-supporting medium or gaseous fuel preheating, form the novel flame type different from traditional flame, and it is more even by reversing combustion, in-furnace temperature to be distributed.
During firing equipment employing heat storage type combustion mode, traditional layout must adopt and be arranged symmetrically with, when for small-sized firing equipment, when such as adopting two burners, the underpower of firing equipment, although and adopt during four burners and reach rated power, but cost improves greatly, namely adopt burner or the heat storage tank of even-even, such layout adds the fund input of firing equipment.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of asymmetric firing equipment, the burner that this firing equipment adopts odd number right, asymmetric arrangement is arranged relative to the tradition routine of heat-storage type burner, reduces equipment investment cost while reaching consumption reduction object.
The purpose of this utility model is achieved in that
A kind of asymmetric firing equipment, comprise heating furnace body, be characterized in: described firing equipment also comprises burner, described burner has odd number, is all arranged on the top of heating furnace body, the top of described burner is fuel gas inlet, right part is air intlet, and bottom is burner outlet, and described burner outlet is in horn-like, burner outlet is located in the burner hearth of heating furnace body, and the air duct inwall of described burner is provided with arc convex near the fluidic junction place of combustion gas and air.
A kind of asymmetric firing equipment of the utility model, its burner has three.
Compared with prior art, the beneficial effects of the utility model are:
1. a kind of asymmetric firing equipment of the utility model, under the effect of arc convex, air forms swirling eddy, produces very large bipyramid ball-type recirculating zone, is formed continuously and steady burning condition at flame root with after combustion gas mixing.
2. the utility model is in operation, always has a burner to be in exhaust condition (resting state), by the combination of three kinds of courses of work, firing equipment can be made to run without interruption, while the power ensureing firing equipment, also improve operating efficiency.
3. the burner that the utility model employing odd number is right, asymmetric arrangement is arranged relative to the tradition routine of heat-storage type burner, reduces equipment investment cost while reaching consumption reduction object.

Detailed description of the invention
See Fig. 1-3, the utility model relates to a kind of asymmetric firing equipment, and it comprises heating furnace body 1 and burner 2, and described burner 2 has three, is all arranged on the top of heating furnace body 1.
See Fig. 4-7, the top of described burner 2 is fuel gas inlet 2.2, and right part is air intlet 2.1, and bottom is burner outlet 2.3, described burner outlet 2.3 is in horn-like, and the air duct inwall of described burner 2 is provided with arc convex 2.6 near fluidic junction 2.5 place of combustion gas and air mixing.
Operation principle: under the effect of arc convex 2.6, air forms swirling eddy, produce very large bipyramid ball-type recirculating zone, formed continuously and steady burning condition at flame root with after combustion gas mixing, and utilize trumpet-shaped burner to export the wall attachment effect of 2.3, flame is close to the outlet side furnace wall of burner 2 to surrounding uniform extension, produce the flat flame of disc, with convective heat transfer to burner hearth, conduct heat to by heated parts with radiation mode, workpiece burning can be avoided.
The course of work one: when the burner 2 at left part and middle part works, air is from respective air intlet 2.1 air intake, and the air intlet of the burner 2 of right part then discharges flue gas.
The course of work two: when the burner 2 of left part and right part works, air is from respective air intlet 2.1 air intake, and the air intlet of the burner 2 at middle part then discharges flue gas.
The course of work three: when the burner 2 of middle part and right part works, air is from respective air intlet 2.1 air intake, and the air intlet of the burner 2 of left part then discharges flue gas.
Above-mentioned three kinds of processes, always have a burner to be in exhaust condition (resting state), by the combination of above-mentioned three kinds of courses of work, firing equipment can be made to run without interruption, while the power ensureing firing equipment, also improve operating efficiency.
The utility model is applicable to small-sized firing equipment, and the burner adopting odd number right or heat storage tank, preferably, burner adopts 3.Asymmetric arrangement is arranged relative to the tradition routine of heat-storage type burner, reduces equipment investment cost while reaching consumption reduction object.
