Burn laboratory and be generally provided with combustion experiment stove, by true simulated combustion situation, analyze the spout impact for combustion efficiency.
Owing to the spout of normal burner typically uses castable (heavy refractory material), for ensureing its stability during installing,
Spout is tightly combined with furnace wall, is difficult to remove through high temperature sintering, therefore, need to carry out the spout in experimentation after installation
Improve.
Application number 201020062527.4 discloses a kind of square burner block, and the center position of burner block body arranges flame dress
Putting, the peripheral profile of burner block body is square, and the exit of flame device is horn-like.Burner block body is by original circle
Changing square structure into, the profile making burner block body is consistent with the shape of the square thermal-insulation of periphery cotton, enhances burner block and insulation
Seal between cotton, it is to avoid steel plate temperature distortion, not only extends the service life of steel plate, and ensure that the peace of production
Quan Xing.Change the sealing between shape strengthening spout and the burner of burner block, it is impossible to meet the requirement that laboratory frequently dismounts.
Application number 200620024395.X discloses a kind of ceramic fiber burner brick, and burner brick body is by the intensive intertexture of warp-wise and broadwise
Ceramic fibre bulk structure, the ceramic fibre of burner block body section be irregular layer structure distribution.Burner block has
Lightweight, fixing difficulty is installed little；Heat insulation effect is strong, the advantage that radiation loss is low.The burner block using ceramic fibre material can
To alleviate the weight of burner block, but the stability of corresponding burner block is greatly reduced, and cannot meet laboratory stable operation equally
Demand.
Summary of the invention
The purpose of the present invention aims to provide one and is easy to dismounting, stable, and repeatable experiment reduces experimental expenses, meets real
Test the experimental furnace burner of requirement.
To this end, the solution that the present invention is taked is:
A kind of experimental furnace burner, including gas inlet pipe, air intlet pipe, hybrid chamber, flange and spout, it is characterised in that
Described spout is spliced by one group of annular jet ring that at least 2 shapes are identical and size is supporting；Described spout ring center has
Taper type spray orifice, side is provided with the taper type mounting groove concentric with spray orifice, and opposite side edge is provided with taper type chuck, previous spray
The spray orifice port of export size shape of choma is identical with the spray orifice entrance point size shape of later spout ring, the peace of later spout ring
Tankage is sleeved in the chuck of previous spout ring, and spout ring foremost is connected with burner hybrid chamber by flange, rearmost end
Spout ring be fixed on experimental furnace furnace wall by wedge shape plug.
It is filled with airtight and watertight padding, the connection of adjacent two spout rings between described spout ring mounting groove and experimental furnace antetheca foremost
Topcoating is provided with refractory fibre.
Described spout ring spray pore cross section is generally circular in shape, rectangle, ellipse or polygon.
Described spout ring mounting groove section configuration is circular or square.
The invention have the benefit that
Owing to present invention employs assembled structure, it is achieved that the experiment burner nozzle of different structure shape, can be according to use
Situation prompt disassembly and installation, shortens experimental period, improves work efficiency, stable, and repeatable experiment uses, significantly
Reduce experimental cost, meet the needs of laboratory combustion experiment.
