Abstract

The utility model relates to a heat storage combustion device which comprises a hearth (9) and a combustion nozzle (11), wherein the hearth (9) and the combustion nozzle (11) are connected together. The combustion nozzle comprises a first gas channel (2), a front chock block (3) of the combustion nozzle, a thermal storage body (4), a back chock block (6) of the combustion nozzle, a casing (7) of the combustion device, an air/ smoke channel (8) and a gas supplying port (10). The combustion nozzle also comprises an air swirler (1) and a secondary gas channel (comprising two or a plurality of gas channels) (5). The air swirler (1) is arranged between the hearth (9) and the combustion nozzle (11). The secondary gas channel (comprising two or a plurality of gas channels) (5) are arranged on the both sides of the first gas channel (2). One end of the secondary gas channel is connected with the hearth (9), and the other end is connected with the gas supplying port (10). The utility model has the advantages that the reaction rate of the gas and the air is accelerated, and the gas combusts completely so as to achieve the combustion effect.

Description

The heat-accumulation combustion device
Technical field
The utility model relates to a kind of burner, relates in particular to a kind of heat-accumulation combustion device.
Background technology
The heat-accumulation combustor of prior art, major defect has: combustion gas generally taps in the burner hearth and the high temperature air diffusion combustion from the heat-accumulating burner central straight.Because combustion gas and air fail to spread fully, mix, combustion gas generally is difficult to completing combustion, has influenced combustion efficiency; And the flue gas that has caused containing a large amount of combustibles directly enters in the heat-accumulating burner on opposite, carries out second-time burning in the offside heat-accumulating burner, causes the heat storage well damage.
Summary of the invention
The utility model technical issues that need to address have provided a kind of heat-accumulation combustion device, are intended to solve because fuel gas buring is insufficient, cause influencing combustion efficiency on the one hand the defective that causes the opposite heat storage to damage on the other hand.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises burner hearth, burner; Described burner hearth and burner link together; Described burner comprises first blast tube, the burner positive stop, and heat storage, the burner backstop, burner housing, air/exhaust gases passes is for gas port; Also comprise air cyclone, second blast tube (comprising two or many blast tubes); Described air cyclone is between burner hearth and burner; In the first blast tube both sides, an end is connected with burner hearth described second blast tube (comprising two or many blast tubes), and the other end links to each other with supplying gas port.
Compared with prior art, the beneficial effects of the utility model are: accelerated the reaction speed of combustion gas and air, made fuel gas buring abundant, reached combustion efficiency.
Description of drawings
Fig. 1 is the heat-accumulation combustion device of prior art;
Fig. 2 is the vertical view of an embodiment of the present utility model;
Fig. 3 is that the A of Fig. 2 is to view;
Wherein: air cyclone 1 first blast tube 2 burner positive stops, 3 heat storages, 4 second blast tubes (comprising two or many blast tubes) 5 burner backstops, 6 burner housings 7 air/exhaust gases passes 8 burner hearths 9 are for gas port 10 burners 11
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2, Fig. 3 as seen: the utility model comprises burner hearth 9, burner 11; Described burner hearth 9 and burner 11 link together; Described burner 11 comprises first blast tube 2, burner positive stop 3, and heat storage 4, burner backstop 6, burner housing 7, air/exhaust gases passes 8 is for gas port 10; Also comprise air cyclone 1, the second blast tube (comprising two or many blast tubes) 5; Described air cyclone 1 is between burner hearth 9 and burner 11; Described second blast tube (comprising two or many blast tubes) 5 is in first blast tube, 2 both sides, and an end is connected with burner hearth 9, and the other end links to each other with supplying gas port 10;
3～80 ° of described air cyclone 1 angles, 2～16 on air stream thigh;
Described angle is 10 °, and air stream thigh is 8;
Because combustion gas enters by first blast tube 2 and 5 fens secondaries of second blast tube (comprising two or many blast tubes), increased air cyclone 1 at burner hearth 9 and burner 11, the jet of gas, the effect of entrainmenting strengthen greatly, by improving the entrainment amount of jet action to flue gas, diluted flammable mixture greatly, cause the condition of low oxygen combustion, realize the discharging of ultralow nitrogen oxide; And the mixing of combustion gas and high temperature air, diffusion also strengthen greatly by the effect of air air cyclone, accelerate the reaction speed of combustion gas and air, and fuel combustion is complete.
The utility model mainly is applicable to natural gas, town gas, contour, the middle calorific value air single regenerative of high coke mixed gas form, can be widely used in gas-fired heater, heat-treatment furnace of coloured, ferrous metal etc.
