摘要： PURPOSE:To reduce NOx by ejecting a fuel and primary air in the tangential direction of a primary virtual circle having a small radius and secondary air in the tangential direction of a secondary virtual circle having a large diameter. CONSTITUTION:A nozzle 8 for a fuel mixed gas is directed toward the tangential direction 14 of a primary virtual circle 12 of a small diameter within a planar section of a furnace 2, and secondary air nozzle 9 is directed toward the tangential direction 15 of a virtual circle 13 concentric with the virtual circle 12 and having a diameter larger than that of the circle 12. Further, air nozzles 10 and 11 are directed toward the tangential direction 17 of a virtual circle 16 concentric with the virtual circle 13 and having a diameter smaller than that of the circle 13. A region of a concentrated reducing atmosphere and a region 20 of an oxidation atmosphere encircling the region 19 are constituted in a space of the furnace by a turning fire ball 18. The reducing atmosphere region 19 is charged with air 11 for three-stage burning. The heat of a gas 22 generated by burning and forming an oxidizing atmosphere at the upper part 21 of the furnace 21 is recovered on the heat transfer surface within a flue 23 and contributes to the generation, overheating and reheating of vapor, thus reaching a boiler outlet 24. Hence, the increase of Nox is prevented by forming the reducing atmosphere at the central portion in the section of the furnace and the oxidation atmosphere in the periphery of the wall of the furnace.

摘要： PURPOSE:To make it possible to reduce the size and production cost as well as destroy bacteria to a satisfactory extent by forming a combustion chamber partitioned with ceramic perforated plates having an opening before and after and installing a plurality of ceramic perforated plates on the downstream side of said combustion chamber with their opening sections made in different positions alternatively. CONSTITUTION:A plurality of ceramic perforated plates 7 are installed on the downstream side of a combustion chamber 2. Their opening sections 7' are provided alternatively in different positions so that gas may flow between the ceramic perforated plates in a zigzag manner. The odor ingredients or the like contained in the gas flowing through bores 6' on ceramic perorated plates 6 on the upperstream side heated to a high temperature by the radiation of flames, are decomposed by heat to some extent. The ceramic perforated plates 7 on the downstream side are further heated by the radiation of flames from a burner 3 and the heated gas flowing through the passage between the perforated plates or the bores on the perforated plates themselves so that the odor component contained in the gas flowing there may be completely heat- decomposed.

摘要： PROBLEM TO BE SOLVED: To provide a flame holder for a boiler burner which is protected against adhesion of carbon. SOLUTION: The flame holder 6 comprising a funnel-like cone 6a at the forward end of a burner guide plate 2, an outer tube 6b, an inner tube 6c, and a reinforcing rib 6d is fixed by inserting a burner gun 3 into the burner guide plate 2 and arranging primary air nozzles 1 on the periphery. The cone 6a is provided with a circumferential primary air intake hole 11 and a guide plate 22 having opposite open sides for forming an air chamber 13 is placed on the upper surface thereof. Fuel is supplied from the burner gun 3 and the primary air 5 is supplied from the primary air nozzles 1. Primary air 5a-5e is supplied into a furnace 10 and mixed with the fuel 4 to form a flame 8 while prime air 5f is jetted from a large number of punched holes 14 of the guide plate 22. Since carbon is prevented from adhering to the surface of the guide plate 22, a ring flame 7 is not distinguished and firing is stabilized.

摘要： PURPOSE:To form a stable flame of combustion by setting a flame scanner in such a manner as to have its tip projecting in the center of a flame holder and by providing the flame holder with an air-diffusing ring. CONSTITUTION:A flame scanner 10 enclosed in a flame scanner protective tube 12, through which cooling air (ambient air) 13 flows, is set with its tip projecting in the center of a flame holder 08. This flame holder 08 is provided with an air-diffusing ring 14 which makes the cooling air 13 flow along the flame holder 08. The cooling air 13 streaming through the flame scanner protective tube 12 is jetted from the center of the flame holder 08. Guided by the air-diffusing ring 14 provided to the flame holder 08, the cooling air 13 is diffused evenly on the surface of the flame holder 08 so that it cools the flame holder 08 on one hand and on the other hand improves the flame-holding effect through mixing with the fuel gas 01 and increase of the oxygen concentration around the flame holder 08. This method makes it possible to use exhaust gas from a gas turbine, whose oxygen concentration is low (10wet.Vol%), as oxygen-mixed gas for combustion and form therefrom a stabilized flame of combustion.

摘要： PURPOSE:To provide the title gasifier having a slag discharge hole which is adapted so that the slag may be prevented from being deposited on and grown around it in order to avoid the stoppage of such a hole occasionally occurring in an entrained bed coal gasifier having a slag discharge hole on the bottom. CONSTITUTION:The lower part of a slag discharge hole 6 is surrounded by a water-cooled jacket 10 protruding beyond the inner surface of the refractory. The jacket 10 has a cylindrical or conical form, and cooling water passes it through pipes 11 and 12. The molten slag formed in the combustion furnace and flowing down into the slag discharge hole is rapidly cooled by contact with the jacket 10 to form brittle rapidly cooled slag, which hangs, then breaks near its upper support and falls.
