Abstract
The utility model relates to a boiler burner cylinder of a coal-fired boiler in a thermal power plant, the utility model discloses an arch bridge wear corundum ceramic liner boiler burner cylinder, which comprises a shell substrate (2) and a corundum ceramic block (4), a plurality of corundum ceramic blocks are stuck on the inner wall of the shell substrate, a plurality of corundum ceramic blocks are tightly arranged to form a burner liner cylinder (6), and via holes are arranged on the shell substrate and the corundum ceramic blocks. A bolt (1) crosses the via hole to fix the shell substrate and the corundum ceramic blocks, a corundum ceramic plug (3) is covered on the via hole of the corundum ceramic block is covered on the bottom of the bolt, and the high temperature inorganic adhesive (5) is coated between the corundum ceramic block and the shell substrate, between the corundum ceramic blocks, between the corundum ceramic block and the corundum ceramic plug. The utility model has the characteristics of abrasion resisting, corrosion resistance and high temperature resistance, and the service life is prolonged number times than a prior cylinder liner material.
Description
Technical field:
The utility model relates to the boiler-burner cylindrical shell of a kind of thermal power plant coal-burning boiler.
Background technology:
The boiler great majority that the coal-burning power plant uses are coal-powder boiler, all need be equipped with the pulverized coal preparation system that lump coal is milled into coal dust.Coal dust enters into the coal-powder boiler combustion power generation by the coal chute road, and especially in the boiler-burner cylindrical shell, because coal dust enters in the burner with certain speed, the impact that cylinder inboard wall constantly is subjected to coal dust is worn and corrodes, and bears certain temperature.Especially at burner cylindrical shell crooked position, be subjected to the effect of coal dust high speed centrifugation power, its wear rate exceeds the straight sections figure place doubly, and cylindrical shell damages easily.Employing that the burners in prior cylindrical shell has increases cylinder inboard wall alloy material thickness or adopts wear resistant alloy material increasing the service life, but cost is higher, and effect is desirable not to the utmost.
Summary of the invention:
The utility model provides a kind of arch (bridge) type abrasion-resistant corundum ceramics liner boiler-burner cylindrical shell, and this liner boiler-burner cylindrical shell has abrasionproof, anticorrosion, resistant to elevated temperatures characteristics, compared with prior art, can prolong the several times in service life of cylindrical shell.
The utility model is achieved in that a kind of arch (bridge) type abrasion-resistant corundum ceramics liner boiler-burner cylindrical shell, comprise the shell base material, it is characterized in that on shell base material inwall, posting polylith corundum ceramic piece, polylith corundum ceramic piece closely rearranges boiler-burner liner cylindrical shell, on shell base material and corundum ceramic piece, have through hole, bolt passes through hole shell base material and corundum ceramic piece is fixed, be stamped the corundum ceramic plug on the corundum ceramic piece through hole bolt bottom is covered, between corundum ceramic piece and shell base material, corundum ceramic piece and corundum ceramic interblock, scribble the high temperature inorganic glue between corundum ceramic piece and corundum ceramic plug.
Operation principle of the present utility model is at burner cylindrical shell inwall layer overlay corundum ceramic, and corundum ceramic adopts bolt to be connected with the cylinder shell base material, and corundum ceramic is fixed on the cylinder inboard wall.Because corundum ceramic has wear-resistant, corrosion-resistant and resistant to elevated temperatures characteristics, so prolong several times than existing cylindrical shell inner lining material its service life.
Description of drawings:
Fig. 1 is the utility model arch (bridge) type abrasion-resistant corundum ceramics liner boiler-burner tube structure schematic diagram, and Fig. 2 is the schematic side view of Fig. 1, and Fig. 3 is the local enlarged diagram of Figure 1A.Among the figure: 1. bolt and nut, 2. shell base material, 3. corundum ceramic plug, 4. corundum ceramic piece, 5. high temperature inorganic glue, 6. liner cylindrical shell.
The embodiment explanation:
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of arch (bridge) type abrasion-resistant corundum ceramics liner boiler-burner cylindrical shell, comprise shell base material 2 and corundum ceramic piece 4, on shell base material 2 inwalls, post polylith corundum ceramic piece 4, polylith corundum ceramic piece 4 closely rearranges boiler-burner liner cylindrical shell 6, on shell base material 2 and corundum ceramic piece 4, have through hole, it is fixing with shell base material 2 and corundum ceramic piece 4 that bolt 1 passes through hole, be stamped corundum ceramic plug 3 on corundum ceramic piece 4 through holes bolt 1 bottom is covered, 2 of corundum ceramic piece 4 and shell base materials, 4 of corundum ceramic piece 4 and corundum ceramic pieces, the slit that corundum ceramic piece 4 and corundum ceramic plug are 3 scribbles high temperature inorganic glue 5.In the present embodiment, shell base material 2 is generally stainless steel material, and corundum ceramic 4,3 can adopt corundum ceramic material No. 95.
The utility model can be applicable to power plant boiler burner cylindrical shell, geomery according to the cylinder shell base material, make the corundum ceramic piece, every corundum ceramic piece by being bolted on the shell base material and using high temperature inorganic glue filleting bonding, is reached the result that shell and corundum ceramic piece are close to after Overheating Treatment.
The utility model also can be applicable to other and needs wear-resistant, corrosion-resistant and resistant to elevated temperatures parts and pipeline.
