Abstract

The utility model discloses a flame accelerator, and aims to provide the flame accelerator which can effectively save energy. The flame accelerator comprises a shell, and is characterized in that: the diameter of an end face of the shell is less than that of another end face; the shell is trumpet-shaped as a whole; and one end of the shell is a cylindrical tubular shell, and the other end of the shell is a conical tubular shell and is connected with the cylindrical tubular shell. One end of the shell is cylindrical, and the other end of the shell is the trumpet-shaped shell of which the inclination is consistent with that of a fire jet passage of a kiln. The shell is made of a high-temperature-resistant hard material. The shell is made of silicon carbide or a high-aluminum high-temperature-resistant material. The flame accelerator is mainly used as an accessory for the kiln.

Description

A kind of flame accelerator

Technical field

The utility model relates to a kind of kiln burner annex, relates in particular to a kind of flame accelerator.

Background technology

The flame passage that band constant slope hole is normally arranged in the top casting of kiln Nell wall or cutting in Industrial Stoves, install combustion device in the flame passage again, the high-temperature flue gas after the burning promptly in the flame passage ejection rapidoprint in the kiln is carried out radiation heating.But installing the end of back flame passage, existing kiln burner certain distance is arranged from the combustion head of burner; the high-temperature flue gas that the burning back is produced can not be by the outside high velocity jet of flame passage; the too short non-uniform temperature that makes in the burner hearth of flue gas injection distance; can strengthen the heating temperature difference that influences rapidoprint; temperature reaches uniform standard in the stove and will make, and just needs to strengthen the conveying capacity of coal gas.So both wasted the energy, the thermal efficiency of kiln also can be lowered.

Summary of the invention

The utility model discloses a kind of flame accelerator, in order to solve energy waste and the big problem of the burner hearth temperature difference that existing kiln causes because of the injection problem of high-temperature flue gas.

Technical solution of the present utility model is: a kind of flame accelerator, comprise housing, and it is characterized in that: an end face diameter of described housing is less than the other end diameter, and it is horn-like that integral body is.

Further, an end of described housing is the tubular shell of column type, and the other end is conical tubular shell and joins with the tubular shell of column type.

Further, an end of described housing is column type, the gradient of other end housing and the consistent horn-like housing of kiln flame passage gradient.

Further, described housing is made by a kind of high temperature resistant hard material.

Further, described housing is made by carborundum or other high alumina exotic material.

The beneficial effects of the utility model are: cover or partly covering by adopting the housing design consistent with flame passage gradient to make distance between the burning nozzles of flame passage front end and burner can be carbonized the housing that silicon makes, the high-temperature flue gas that burning produces can be fettered by housing and be ejected into the farther place with higher speed under the effect in burning expansion under the trumpet-shaped shape of housing, thereby the deficiencies in the prior art have fundamentally been solved, the energy and the thermal efficiency that has improved kiln had both been saved, can be ejected into higher speed in the burner hearth because of high-temperature flue gas again, more effectively stirred the flue gas in the burner hearth, make the temperature difference in the burner hearth greatly reduce, given the rapidoprint in the burner hearth heating environment of more optimizing.

Among the figure: 1-housing, 2-flame passage.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Referring to accompanying drawing 1-2, utility model own comprises housing 1, it is characterized in that: an end face diameter of described housing 1 is less than the other end diameter, and it is horn-like that integral body is.

One end of described housing 1 is the tubular shell of column type, and the other end is conical tubular shell and joins with the tubular shell of column type.

One end of described housing 1 is column type, the gradient of other end housing and the consistent horn-like housing of kiln flame passage 2 gradients.

Described housing 1 is made by a kind of high temperature resistant hard material.

Described housing 1 is made by carborundum or other high alumina exotic material.

When reality is used, at first will produce according to the flame accelerator that the utility model is produced.On the equipment that in kiln, need is installed additional burner is extracted, then the flame accelerator directly is inserted into the tail end of flame passage 2 by flame passage 2 installation ends and fixes according to the gradient of flame passage 2.It is installation that the nozzles that will burn at last insert.Combustion gas and air are in flame passage 2 internal combustion and push ahead under the effect of burning expansion and flue gas during use, and the high-temperature flue gas that burning at this moment produces is by in the housing of being made by carborundum or other high alumina temperature-resistant material 1.Because the outlet diameter of housing 1 is less, the high-temperature flue gas that burning produces obtains accelerating jetting in the exit, thereby just can spray fartherly, more effectively stir the flue gas in the burner hearth, make burner hearth reach the purpose of samming, thereby realized design original intention of the present utility model, reached desirable effect.
