Title: Catalytic burner
Inventor: SHIMADA RYOJI
IPC: F23D14/18
Filed: 1984-12-19
Abstract: PURPOSE:To contrive to obtain a longer service life of a catalytic activation property of a catalyst by a method wherein a desulpherizing catalyst layer is set up between a fuel supplying unit and a combustion catalytic body so as to reduce an impact of sulpher content of a odorant containing in a fuel against an oxidative catalyst to a minimum level. CONSTITUTION:When a combustion catalytic body 8 comes to reach a constant level of temperature by ignition, then power supply to a preheater 7 is stopped, the catalysis combustion in the combustion catalytic body 8 become a steady combustion of some 450-550 deg.C. At this time, the desulpherizing catalyst layer 6, which is contacting to the rear surface of the combustion catalytic body 8 has received a conductive heat from the above catalytic body 8, therefore its temperature is increased to about 350 deg.C. Zinc-oxide contained in the desulpherizing catalyst layer 6 has the property of absorbing sulpher in the highest level at the temperature around 350 deg.C. Accordingly, when the fuel gas is passing through the desulpherizing catalyst layer 6, the sulpher content of the odorant mixed in the fuel is fully absorbed by the zinc-oxide, therefore, at the time when the fuel gas has reached the combustion catalytic body 8, the sulpher concentration in the fuel gas has become below 1ppm, which indicates the impact against the combustion catalytic body may be restricted to a minimum level.

CONSTITUTION:A thin film 2 made of material whose crystal seed forming density is low (for instance non-single-crystalline SiO2) is built up on a quartz substrate 1 to form a non-seed- forming surface 3. Non-single-crystalline Al2O3 layers 4 which have a higher seed forming density than the surface 3 are formed. The area of the layer 4 is not larger than 2mum square, i.e., the area in which only one seed can be formed. II-V compound crystal seeds 9 are created by an MOCVD method. In an initial stage, a reaction pressure is selected to be 0.1Torr and a V-group/III-group mol ratio of raw gas is selected to be non less than 45 to avoid the defects caused by the lack of V-group atoms. In the growth stage of single crystals 10 after the crystal seeds 9 are made to grow, the reaction pressure is selected to be the atmospheric pressure and the V-group/III-group mol ratio is selected to be not less than 28 to avoid the waste consumption of the V-group raw material. After that, the crystals are made to grow horizontally onto the non-seed-forming surface 3. With this constitution, the high quality III-V compound single crystals can be obtained efficiently and with a high growth speed.
