摘要： PURPOSE:To obtain a burner structure in which a ceramic diffuser cone having excellent durability is mounted by fixing a jacket tube and the cone by a heat resistant fastener in which a curvature of a surface of the cone in contact with a periphery of a cylinder is equal to an outer diameter of the cylinder. CONSTITUTION:A burner for combustion has a diffuser cone part 11 and a cylinder 12 having an inner diameter of the same curvature as outer diameters of a diffuser cone 11 and a metal jacket tube 2. Diffuser cone members 10 of the divided cones 11 are placed on an outer periphery of the tube 2, and fixed by a clamping nut 3 through a heat resistant fastener 5 having the same curvature as that of an outer periphery 17 of the cylinder 12 of the cone 1 at a surface 21 of the cone 1 in contact with the cylinder 12. Thus, the divided members can vary similarly to the tube in coincidence with an expansion amount of the tube.

摘要： PURPOSE:A combustion burner structure has a diffuser cone of ceramics which is superior in durability and capable of being used continuously for a long period of time. CONSTITUTION:A combustion burner structure is provided with a diffuser cone 1 of ceramics at a metallic jacket tube 2. A method for connecting and fixing both elements is not a method for making some bolt insertion holes in the diffuser cone 1 of ceramics and fastening them with bolts, but the diffuser cone 1 of ceramics is provided with a connecting projection 14. The projection 14 and the metallic jacket tube 2 are fixed by a metallic clamp 3 divided into several segments.

摘要： PURPOSE:To obtain a light rare earth oxide sintered body having high sintering density by roasting acidic aq. soln. slurry of the powdery compd. of specific light rare earth element by a casting molding method. CONSTITUTION:Slurry for a raw material is obtained by mixing the powdery compd. of a light rare earth element selected from among lanthanum, cerium, praseodymium and neodymium in an acidic aq. soln. having pH of 0 - 5. The aimed sintered body is obtained by sintering this slurry for the raw material by a casting molding method. Therein, the temp. necessary for sintering is 900 - 1900 deg.C and especially is preferably regulated to a range within 1200 - 1700 deg.C. When this temp. is lower than 900 deg.C, a dense sintered body is not obtained because sintering is insufficient. Further, when the temp. exceeds 1900 deg.C, this case is unpreferable because the sintered body may be melted. In the case of sintering, when sintering is performed after the slurry is once calcined at low temp. (500 - 900 deg.C), density of the obtained sintered body may be enhanced.
