Abstract

The utility model relates to a distributor of a combustor, comprising an annular distributing disk, a mounting plate which is arranged under the distributing disk and a clearance distance from the distributing disk, an big annular mixing beard which is arranged on the annular distributing disk, and two asymmetric air inlets on the beard, wherein the position of the air inlets is corresponded with the air outlets of the outlet back of the combustor. The utility model is characterized in that the center cavity of the annular distributing disk is arranged inside with a small annular mixing beard with a center via-hole, the small annular mixing beard is provided with air inlets of which the position is corresponded with the center air outlets of the outlet back of the combustor, the outer wall of the small annular mixing beard is a clearance distance from the inner wall of the center cavity. The first and the second intake air is mixed with the gas inside the big annular mixing beard and the small annular mixing beard respectively after coming into the clearance and the center via-hole from the furnace surface, and the gas is burnt adequately. The air intake method is capable of lowering the temperature of the distributor and the outlet back, thereby facilitating the intake and mixing of air. The utility model has the advantages of high burning efficiency, simple structure, and easy manufacture.

Description

The distributor of burner

Technical field

The utility model relates to a kind of distributor of burner.

Background technology

The distributor of burners in prior comprises annular water diversion disk, is located at the gas outlet that annular branch fire coils the installing plate of below and is located at the fiery disk center of annular branch cavity, and it can not well mix the combustion gas that enters with air, and combustion rate is not high.

The utility model content

The purpose of this utility model provides and a kind ofly can make the combustion gas that enters well mix the distributor of the burner that efficiency of combustion is high with air.

In order to achieve the above object, the utility model is to realize like this, it is a kind of distributor of burner, comprising annular branch fire dish and being located at annular divides fiery dish below installing plate gapped with it, divide fire to coil in annular and be provided with the mixed gas groove of big annular, be provided with the air inlet of two symmetries on groove, the give vent to anger gas outlet of pedestal of the position of this air inlet and burner is corresponding; It is characterized in that: the annular that is provided with little band central through hole in the center cavity that annular divides fire to coil is mixed the gas groove, on this groove, be provided with air inlet, the give vent to anger gas outlet, center of pedestal of the position of this air inlet and burner is corresponding, and it is gapped that little annular is mixed the inwall of the outer wall of gas groove and center cavity.

Two air inlets that mix the gas groove in described big annular are respectively equipped with the tube connector that connects the pedestal gas outlet, are respectively equipped with two catch that reduce intake velocity in the outlet side of two air inlets.

Described two catch difference support is on two walls of groove.

The air inlet that mixes the gas groove in described little annular is provided with the catch that reduces intake velocity.

Described little annular is mixed the gas groove and is divided the center cavity inwall of fire dish to be connected by support arm more than three and annular.

Described little annular is mixed the gas groove and is fixed on the installing plate.

On two walls of the mixed gas groove of described big annular, have and give vent to anger or mixed gas breach, on the outer wall of the mixed gas groove of little annular, all have and give vent to anger or mixed gas breach.

The utility model advantage compared with prior art is, first and second air intake can be after boiler face enters gap and central through hole mixes gas groove and little annular with big annular respectively again and mixes combustion gas mixing the gas groove, combustion gas is fully burnt, this kind air intake mode also can reduce the temperature of the distributor and the pedestal of giving vent to anger, helping primary air better enters and mixes, the efficiency of combustion height, simple in structure, make easily.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one

As shown in Figures 1 to 3, it is a kind of distributor of burner, comprises annular branch fire dish 3 and be located at annular dividing fiery dish below installing plate 4 gapped with it.Divide in annular to be provided with big annular on the fire dish and to mix gas groove 34, be provided with the air inlet 32 of two symmetries on groove, give vent to anger basic 7 gas outlet 72 of the position of this air inlet and burner is corresponding; Be respectively equipped with the tube connector 8 that connects the pedestal gas outlet at annular greatly two air inlets 32 that mix gas groove 34, be respectively equipped with on two walls of two catch 5, two catch, 5 difference supports that reduce intake velocity at groove in the outlet side of two air inlets 32.Fixing being provided with has the mixed gas groove 35 of central through hole 39 little annulars in the center cavity of annular branch fire dish 3, on this groove, be provided with air inlet 31, the give vent to anger gas outlet, center 71 of pedestal 7 of the position of this air inlet and burner is corresponding, be provided with the catch 6 that reduces intake velocity at air inlet 31, little annular is mixed gas groove 35 and is divided the center cavity inwall of fire dish to be connected with the inwall of center cavity gapped 43 and by three support arms 33 and annular.

During use, as shown in Figure 1, the distributor install combustion device of burner is given vent to anger on the pedestal 7, will divide fire lid 2 and little branchs fire to cover 1 more greatly and be placed on the distributor of burner; Outer ring at big branch fire lid is provided with fire output hole 22, and circle also is provided with fire output hole 23 within it, covers at big branch fire and is provided with the groove 21 of igniting; On little branch fire lid 1, be provided with two and iris out

fire hole

11,12; Use this distributor can produce four circle flames, the efficiency of combustion height, flame is bigger.

Embodiment two

As shown in Figure 4, other structure is the same with embodiment one, and different is to have to give vent to anger or mixed gas breach 37 on two walls of the mixed gas groove 34 of big annular, mixes the gas groove in little annular and is fixed on the installing plate 4, all has on its outer wall and gives vent to anger or mixed gas breach 38.

The same during use with embodiment one, owing on the mixed gas groove walls of size, have breach, therefore divide fire to cover and do not need to leave fire hole in size.It also can produce four circle flames, the efficiency of combustion height, and flame is bigger.
