摘要： PURPOSE:To enhance the performance of a catalytically active component and to obtain a catalytic body for high-temp. combustion having high activity and a long service life by supporting the catalytically active component on particles of nonoxide ceramics and using the resulting catalytic particles. CONSTITUTION:A porous carrier layer of alumina, titania, etc., is stuck to the base material of a carrier such as cordierite or mullite. A catalytically active component such as Pd or Pt is supported on particles of nonoxide ceramics such as silicon nitride or silicon carbide to obtain catalytic particles whose particle size is stabilized at a catalytic combustion temp. The catalytic particles are filled into the pores in the porous carrier layer. The resulting catalytic body for high-temp. combustion has higher performance than particles of only the catalytically active component and is hardly deteriorated even after use for a long time.

摘要： PURPOSE:To enable the replacement time of a catalyst assembly to be easily found, by providing a branched flow path which is connected to a vapor phase combustion chamber formed in the downstream of the catalyst assembly and which is packed with an unburnt detecting catalyst assembly, and by providing a temperature-rise detecting means for checking a catalytic reaction in the branched flow path. CONSTITUTION:Fuel 2 fed out of a fuel feeding nozzle 1 is mixed with air for combustion to be preburnt, and after the temperature of the fuel-air mixture is elevated up to a level of the action temperature of a catalyst assembly 10, said fuel-air mixture is mixed with fuel fed out of fuel feeding nozzles 9 to be converted into a fuel-air mixture gas and flows into the catalyst assembly 10. When a catalytic reaction is incomplete owing to deterioration of the catalyst assembly 10, the fuel gas discharged from the catalyst assembly 10 contains much of unburnt fuel, but such unburnt fuel is further subjected to catalytic combustion in a branched flow path 13 by a catalyst assembly 14 for unburnt fuel detection to elevate its temperature. In this case, a difference in a temperature is caused between thermocouples 16 and 17 adapted at the foe and aft parts of the detecting catalyst assembly 14, and a temperature rise is detected. The degree of deterioration of the catalyst assembly 10 is estimated on the basis of the degree of a temperature rise between the thermocouples 16 and 17, thereby enabling the replacement time of the catalyst assembly 10 to be found.

摘要： PURPOSE:To make it possible to stabilize gas phase combustion by providing a vortex flow generating part between a catalytic combustion part and a gas phase combustion part to throttle the flow passage, and thereafter abruptly to expand the same. CONSTITUTION:A fuel mixture from a catalyst body 7 and an auxiliary fuel mixture from an auxiliary fuel nozzle 12 are formed into desire mixed fuel flows and sent downstream and contracted gently at a throat part 13. Thereafter, these flows are abruptly expanded at a gas phase combustion part 14, and a stable vortex flow (circulating flow) 15 is produced along the circumference of the gas phase combustion part at the rear part of the throat part 13. This vortex flow 15 is not almost affected even if a disturbance is produced in a mixed flow passing the center of the flow path of the throat part 13, and hence a stable vortex flow is formed. Thus, since a vortex flow is produced along the circumference of the gas phase combustion part, a flame holding effect is produced, and hence even if local misfiring is generated, it is not enlarged but an original uniform combustion state is restored immediately, and a stable gas phase combustion can be carried out.

摘要： PURPOSE:To suppress an abnormal increase in temperature of a catalyst, enable a long life of the catalyst, reduce a pressure loss within a catalyst charging area and improve an efficiency of combustion by a method wherein a temperature of the catalyst charging area and a ratio in volume of fuel gas and air (F/A) are controlled to each other. CONSTITUTION:Fuel and air are injected from a fuel nozzle 11 and an air injection port into an area A indicated by a dotted line in compliance with a set condition of combustion gas within a gas turbine nozzle 6 so as to form first mixture of desired mixing ratio (F/A). A catalyst charging area B filled with a combustion catalyst 13 is arranged at a rear stage of the area A and a part of the first mixture is ignited with catalyst. The rear stage is provided with an area C for supplying a desired amount of fuel from a fuel nozzle 11a to the flowing-out gas containing unburnt material and igniting the mixture. The catalyst charging area B is provided with means 14 for sensing catalyst temperature and means 15 for adjusting air volume operating in cooperation with the sensing means 14. Since the catalyst temperature and F/A are controlled to each other, an abnormal high temperature of the catalyst can be suppressed.

摘要： PURPOSE:To reduce NOx and improve efficiency of combustion by detecting outflow temperature at a medium outlet to control air fuel ratio according to said temperature while regulating fuel supply downstream of the medium according to the air fuel ratio. CONSTITUTION:Outflow temperature at a medium outlet is detected by a thermometer 9. When said temperature is lower than fire point of thin fuel, an electromagnetic 10 for supplying fuel to a portion downstream of the medium is closed to reduce fuel supply from said portion and increase and air fuel raio in mixture supplied from a portion upstream of the medium. And when the temperature detected by the thermometer 19 exceeds the heat resisting temperature of the medium, said operation is reversely carried out. Thus, nitrogen oxide is reduced to improve the efficiency of combustion.

摘要： PURPOSE:To provide the titled device with an capability of maintaining a preset low ignition temperature, by arranging a group of columns transversely across a gaseous mixture stream between catalysts of honeycomb structure. CONSTITUTION:A visible radiation ray emitted between an upstream and a downstream sections can be shielded by a group of columns arranged in a zigzag manner between two catalysts of honeycomb structure. Moreover, a gaseous mixture is caused to change its flowing direction upon its collision with columns, resulting in bringing about a further mixing action. As a result, it is relatively easy to control the flow velocity of gaseous mixture at an even level after passed across the group of columns. The diameter, number and installation pitches etc., of columns may be determined with a basis on the magnitude of pressure drop required with an arrangement 8. The replacement of arrangements 8 can be performed conveniently by premounting the group of columns as a unit upon a cylinder which can be inserted into the inner diameter of combustion.
