Description
Technical field
The utility model relates to a kind of Downwind type preheating furnaces.
Background technique
Preheating furnace is a kind of by inferior matter dyestuff (referring mainly to blast furnace gas, heating gas, the low heat values such as tail gas dyestuff) or sky
Gas exchanges heat in the high-temperature flue gas of heating furnace by heat exchanger, and inferior matter dyestuff or air themperature are improved, generally to 300 ~
900 DEG C, to improve the actual combustion temperature of dyestuff inferior or the sensible heat of air, reach inferior matter dyestuff high-temperature calcination or its
Dyestuff is further greatly saved so that substituting high-quality dyestuff realizes inferior matter dyestuff to the substitution of high-quality dyestuff in his technique
Cost.Meanwhile the discharge of inferior matter dyestuff or tail gas is decreased, reduce pollution.But the burner pair on existing preheating furnace
Inferior matter dyestuff is insufficient when burning, and is easy to stop working, and the temperature in furnace is difficult record and control.
Summary of the invention
In view of the deficienciess of the prior art, the purpose of this utility model, which is that, provides a kind of Downwind type preheating furnace,
Burner enters in burner hearth in furnace body both sides oblique cutting, and air inducing enters burner hearth from furnace body end, does not influence combustion flame, air inducing and flame side
To consistent, burning is not stopped working sufficiently.
To achieve the goals above, the technical solution adopted in the utility model is such that a kind of Downwind type preheating furnace, packet
Include furnace body, burner, induced pipe, the furnace body includes shell and the burner hearth that is set in shell;One end of the shell
Air inlet is offered, another end offers air outlet, and the air inlet is connected with induced pipe;It opens the side of the shell
Equipped with burner installing port, the burner oblique cutting enters burner installing port and is set in burner hearth;The induced pipe by air inducing from into
Air port, which enters in burner hearth, draws after the flame full combustion of burner from air outlet, the flame direction of the burner and air inducing direction
Unanimously.
As a preferred embodiment, the oblique cutting angle of the burner is 30 ~ 60 °.
As a preferred embodiment, the furnace body further includes having insulating layer, the insulating layer be set to shell and burner hearth it
Between.
As a preferred embodiment, the insulating layer is divided into the inner thermal insulating layer close to burner hearth and the external thermal insulation close to shell
Layer, the inner thermal insulating layer are castable refractory insulating layer, and the outer heat insulation layer is alumina silicate insulating layer.
As a preferred embodiment, be provided at the top of the furnace body to the first thermometric for controlling ignition temperature it is even with to
The second thermometric for recording ignition temperature is even, and first thermometric is even and the second thermometric occasionally sequentially passes through shell, insulating layer is arranged
In in burner hearth.
As a preferred embodiment, the bottom of furnace body is provided with support base, which is connected with shell.
Compared with prior art, the utility model has the beneficial effects that the utility model burner enters furnace in furnace body both sides oblique cutting
In thorax, air inducing enters burner hearth from furnace body end, does not influence combustion flame, and air inducing is consistent with flame direction, and burning is not stopped working sufficiently,
It can further care for and the temperature in burner hearth is recorded and controlled.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model;
Fig. 2 is the top view of the utility model.
Specific embodiment
The utility model is further described combined with specific embodiments below.Following embodiment is only used for clearly
Illustrate the technical solution of the utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
Embodiment:
As shown in Figure 1 and 2, a kind of Downwind type preheating furnace, including furnace body 1, burner 2, induced pipe 3, the furnace body 1 include
