Abstract

The utility model relates to an infrared burner, particularly a burner used for the methane gas burning operation. For the present burning operation, the burner containing the methane gas has low heat efficiency. The utility model has the technical scheme that the utility model can provide the burner using the infrared ray. The utility model is composed of an independent basal burner (1) and a plurality of auxiliary burners (2). The number of the auxiliary burners can be decided by the specific heat load, so that when the heat load is reduced until to be completed by the independent basal burner (1), the auxiliary burners (2) can be left out. A burning head (7) of the basal burner (1) is similar to a pipe smoking tobacco; an air passage (11) of a burning head (8) of each auxiliary burner (2) is in an annular groove shape; the air passage (11) is sheathed at the outer part of the burning head (7) of the basal burner (1). The basal burner and the auxiliary burners are cast or welded into integration. The utility model is characterized in that an air outlet hole (12) of the basal burner (1) is arranged at the centric position of the basal burner; an air outlet hole (13) of each auxiliary burner (2) is arranged at the side position deflective to the rear part of each auxiliary burner; a folding jet exhauster is respectively and smoothly connected with the burning heads (7) and (8) of the burners by two jet-exhauster elbows (6); a ceramic fire cover (9) can be arranged in a stop shoulder (10) which is arranged above the burning heads (7) and (8).

Description

Infrared burner

Affiliated technical field

The utility model relates to burner, is specially adapted to the methane gas burner.

Background technology

At present, the burner of the main methane-containing gas of known burning is by diffusion type burner and atmospheric burner.Atmospheric burner mainly is made up of nozzle, injector, burner head, metal fire lid etc.They all do not reach optimum efficiency to the activation energy raising of fuel gas with efficiency of combustion.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned defective, and a kind of content of infrared burner of the main methane-containing gas that burns is provided.

Scheme of the present utility model is:

Be placed with pottery magnetic fire lid on the shoulder block of burner head, be placed with pottery magnetic fire lid on the shoulder block of the endless groove of auxiliary burner.

Advantage of the present utility model is:

1, excess air coefficient is brought up to 1＜K＜1.2 by K＜1 of air suspended type.

2, convergent-divergent shape injector and burner head are to link with the elbow rounding off.

3, the metal skull is used nonmetallic pottery magnetic fire lid instead.

The beneficial effects of the utility model are by above measure the atmospheric burning type mode to be changed over combustion system based on the infrared ray combustion system.

1, infrared burner is divided into two to burning institute liberated heat partly, some is used for heating nonmetal pottery magnetic fire lid, make pottery magnetic fire cap surface temperature T r 〉=800 ℃, by the outside radiations heat energy of radiating surface, another heat heating flue gas partly is still with the convection type heating object.

2,, thereby reduce NOX content in the flue gas because 800 ℃＜Tr＜1100 ℃.

3, reduce irreversible heat transfer temperature difference.

4, utilize the amount of stored heat of pottery magnetic fire lid to come heating fuel gas, improve the activation energy of gas.

Just because of above 4 points are arranged, so this infrared burner has very high combustion thermal efficiency.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model profile.

Fig. 2 is the utility model vertical view.

Fig. 3 is the basic burner configuration figure of the utility model.

Fig. 4 is the utility model auxiliary burner structural map.

Fig. 5 is that the schematic diagram how the utility model pottery magnetic fire lid is placed on the burner head is shoulder block figure.

Fig. 6 is pottery magnetic fire lid figure of the present utility model.

The specific embodiment:

As shown in Figure 1, the utility model can be divided into basic burner (1) and increase several auxiliary burners (2) according to the burning load size.The similar substantially opium pipe of taking out tobacco of the shape of burner, its essential structure is nozzle receptacle (3), injector throat (4), injector mixing tube (5), injector elbow (6), burner head (7) and (8), pottery magnetic fire lid (9), places the shoulder block (10) of pottery magnetic fire lid (9) that auxiliary burner combustion head (8) is a ring-type flute profile airway (11).

As shown in Figure 2, the venthole (12) of the basic burner of the utility model (1) is at positive center, and the venthole (13) of auxiliary burner (2) is the next door after partially.The vertical view of the combustion head of auxiliary burner (8) is an annular, and the central authorities of annular are the combustion heads (7) of basic burner (1).If thermic load increases, can increase auxiliary burner (2), i.e. one deck cover one deck.

As shown in Figure 5, a shoulder block (10) is arranged on the utility model burner head.

As shown in Figure 6, be pottery magnetic fire lid of the present utility model (9), it is positioned over the top of the shoulder block (10) of Fig. 5.

The utility model technology is to utilize infrared burner in sum.It is by independently basic burner (1) and some auxiliary burners (2) are formed.Fixed with several auxiliary burners by concrete thermic load, when thermic load little to by independently substantially burner (1) can remove auxiliary burner (2) when finishing.The basic similar tobacco pipe of smoking the Chinese of burner (1) combustion head (7), auxiliary burner (2) combustion head (8) airway (11) is the ring-type flute profile, is enclosed within combustion head (7) outside of basic burner (1).Basic burner and auxiliary burner can be castings or integrally welded, the venthole (12) that it is characterized in that basic burner (1) is in the center, auxiliary burner (2) venthole (13) is the next door after partially, with convergent-divergent injector and burner head (7) and (8) slick and sly binding, combustion head (7) and (8), upper position are equipped with a shoulder block (10) can place pottery magnetic fire lid (9) to two injector elbows (6) respectively.

Combustion gas is sprayed to injector throat (4) with very high speed through gas nozzle, because the flow velocity maximum pressure minimum of throat position, thereby can once suck the necessary whole air capacities of burning, combustion gas and inhaled air in the mixing tube (5) of the injector of gradually putting shape because separately speed, concentration and proportion the different and phase counterdiffusion mixes gradually, and carry out the process that reduction of speed boosts, thereby recover certain static pressure, be pressed into the passage and the ring-type flute profile gas passage (11) of the burner head (7) and the similar tobacco pipe of (8) equably through injector elbow (6), and the pottery magnetic fire lid (9) that passes the shoulder block (10) that is positioned on burner head (7) and (8) run into igniter naked light and after blazing up several minutes, pottery magnetic fire lid can be burnt red, and object is heated with the form of infrared ray and convection current, simultaneously scorching hot pottery magnetic fire lid also heats the methane gas that passes it, improves the activation energy of methane gas.
