Abstract
The invention discloses a combustion head of a radiant tube, wherein an air distributor is arranged in the radiant tube; a first-section fire nozzle and a second-section fire nozzle are sequentially arranged in the distributor; a rotational flow flame holder is arranged on the second-section fire nozzle; and a sound damping flame tube is arranged at an exit of the second-section fire nozzle. The combustion head disclosed by the invention has the characteristics that: the combustion intensity is reduced to the limit; the combustion noise is also reduced to the limit and reduced to a the noise level of a fan of a combustor; the heat release of the radiant tube is uniform; the heating uniformity of a heated medium is improved; and the service life of the radiant tube is prolonged in the mean time.
Description
Technical field
The present invention relates to a kind of radiant tube combustion head.
Background technology
Rifle formula gas burner, generally ask the designed combustion head with enough large-scale combustion skies, if in the such small space burning of radiant tube, will produce mismatch problems such as high noisy oscillation combustion, on the lance-type burner basis, multiple ways such as the air intake noise reduction of attempting, flame noise reduction all can not solve the high noisy root problem, have to reduce combustion intensity and just can deal with problems.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of radiant tube combustion head is provided.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of radiant tube combustion head, air distributor is installed in the radiant tube, be provided with one section fire-fighting mouth and two sections fire-fighting mouths in the described air distributor successively, on described two sections fire-fighting mouths the eddy flow flame holder is installed, described two sections fire-fighting mouth exits are equipped with the noise reduction burner inner liner.
Described noise reduction burner inner liner is provided with bloop.
Characteristics of the present invention are: combustion intensity is reduced to the limit, and combustion noise also is reduced to the limit, be reduced to burner fan noise level, and the radiant tube heat release is even, has improved being heated evenly property of heated medium, has prolonged radiant tube service life simultaneously.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
Wherein: 1, air distributor 2, one section fire-fighting mouth 3, eddy flow flame holder 4, two sections fire-fighting mouths 5, noise reduction burner inner liner 6, bloop 7, radiant tube.
The specific embodiment
As shown in Figure 1, in the radiant tube 7 of the present invention air distributor 1 is installed, be provided with one section fire-fighting mouth 2 and two sections fire-fighting mouths 4 in the described air distributor 1 successively, on described two sections fire-fighting mouths 4 eddy flow flame holder 3 is installed, described two sections fire-fighting mouth 4 exits are equipped with noise reduction burner inner liner 5, and described noise reduction burner inner liner 5 is provided with bloop 6.
During work, air from blower fan is divided into two road air-flows through air distributor 1, the combustion gas mixing of one road air-flow and one section fire-fighting mouth 2 ejection, through eddy flow flame holder 3 postignitions burning, form one section fire in noise reduction burner inner liner 5, another road air-flow enters blending limit, the combustion gas limit burning of penetrating with two sections fire-fighting mouths 4 in the radiant tube 7, under the cyclonic action of eddy flow flame holder 3, auxiliary air and one section fire and two sections fire hang down the eddy flow degree and force blending, carry out diffusion combustion and after-flame in radiant tube 7.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
