摘要： PURPOSE:To improve mixture, ignition, flame stabilizing performance by composing a baffle plate of a main baffle for shutting OFF flow of gas, and a plurality of radial auxiliary baffles for dividing the flow at the periphery. CONSTITUTION:A baffle plate 40 is composed of a central baffle 41 for shutting OFF the flow of gas at the center, and a plurality of radial auxiliary baffles 42a, 42b, 42c, 42d for dividing the flow of gas at the periphery. Cutouts 44 narrowed in width of the auxiliary baffles from the ends toward the roots are formed at the roots of one sides of the baffles 42a, 42b, 42c, 42d, the directions of the flows divided by the baffles 42a, 42b, 42c, 42d are twisted to the axis of the flow, and directed to a negative pressure part 43 of the downstream of the baffle 41. Thus, the flows are not collided, but smoothly whirled, wound with part of the dilute premixture gas to be injected from a premixture gas supply unit 4 to be suitably mixed.

摘要： PROBLEM TO BE SOLVED: To diagnose a combustion state by judging at which level a high temperature air combustion is realized and quantitatively detecting oxygen concentration and temperature of oxidizer immediately before a combustion reaction in a furnace in relation of the high temperature air combustion. SOLUTION: CH radical emitting light intensity and C2 radical emitting light intensity are measured. Then, oxygen concentration and temperature of combustion air of oxidizer complicately changing in a furnace immediately before a combustion reaction of hydrocarbon fuel, fuel containing hydrocarbon, or fuel added with the hydrocarbon fuel or hydrocarbon as a marker are estimated from their ratio. Whether the combustion arises high temperature air combustion with extremely low velocity oxidizing exothermic reaction or not can be diagnosed from the ratio of the intensities or at which level the high temperature air combustion is can be diagnosed.

摘要： PURPOSE:To reduce a pressure loss, to form a simple structure by alternately continuously forming crests and troughs circumferentially of the outer surface of an inner cylinder, increasing the crests in diameter smoothly in flowing direction of second fluid, providing a wall crossing the flowing direction of the second fluid at the end, and opening a first fluid jet port, and surrounding it with an outer cylinder. CONSTITUTION:A premixer 30 is composed of a pedal-shaped fuel nozzle 32 having crests 34 smoothly increasing in an outer diameter in the flowing direction of the air and troughs 33 parallel to the flowing direction of the air to be alternately circumferentially provided at a predetermined interval, and an air supply tube 31 for surrounding the nozzle in such a manner that the air flowing through the troughs 33 flows to a negative pressure part formed at the downstream side of the crests 34 to mix the air with fuel. The fuel jet port 35 of the nozzle 32 is opened at the wall 36 of the crest 34 to inject in the air flowing direction. The air of second fluid flows through the troughs 33 of the nozzle 32. Thus, fuel can be diffused without increasing the pressure loss of an air stream.

摘要： PROBLEM TO BE SOLVED: To provide a burner combustion method wherein there is accompanied by an oxidization heat production reaction where a heat production rate is enough low as compared with ordinary combustion, and a fire flame is formed stably in a wide space, and further a fire flame volume is very greatly stabilized and combusted. SOLUTION: There are brought into contact high temperature diluted air that is very lower than ordinary air at least before a combustion reaction and above combustion stabilization limit temperature of mixed air at that oxygen concentration or a corresponding oxidizing agent and a fuel in a furnace, which are therefore stably combusted under an oxidization heat production reaction at a very low speed. The combustion is securely achieved by adding a hydrocarbon fuel or hydrocarbon as a marker when the hydrocarbon fuel is used as a fuel or even when a fuel not including hydrocarbon is used, and keeping the combustion in the state where it is green colored.

摘要： PROBLEM TO BE SOLVED: To uniformize the heat flux without increasing a furnace volume of a tubular heating furnace while keeping the close arrangement of heating pipes. SOLUTION: A hot diluted air preheated at a temperature above a critical blow-off temperature and having remarkably low oxygen concentration relative to normal air is produced by mixing air with a part of combustion exhaust gas discharged from a tubular heating furnace. The hot diluted air and a fuel are subjected to diffusion combustion in a tubular heating furnace without changing the chemical equivalent ratio of the optimum air ratio and the hot gas flow is intermittently, continuously or periodically flowed around the heating pipes to heat the fluid in the heating pipes.

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply unit and a fuel supply method in which the mixing process of fuel, fuel gas and combustion air can be enhanced along with the controllability of mixing ratio. SOLUTION: The fuel supply unit comprises a fuel supply means, a combustion gas delivery unit, a steam supply unit, a mixing unit and a fuel gas introduction unit. The combustion gas delivery unit delivers combustion gas produced in a combustion zone to the outside of a furnace. The mixing unit mixes combustion gas and/or steam with fuel from the fuel supply means. The fuel gas introduction unit introduces the mixture fluid of combustion gas, steam and fuel, as fuel gas, to the combustion zone and mixes combustion gas with combustion air. Since a step for mixing combustion gas and/or steam with fuel and a step for mixing the mixture fluid further with combustion air are executed stepwise, mixing process of fuel and combustion air and controllability of mixing ratio are enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a combustion device and a combustion method in which the controllability of a combustion flow entering a combustion area is improved and a flame property can be controlled under the control of the combustion flow. SOLUTION: A combustion device comprises a combustion air feeder for introducing air for combustion to a combustion area, a combustion gas discharge device, a steam feeder, a mixer (mixing area) and a fuel gas introducing device. The combustion gas discharge device discharges the combustion gas generated in the combustion area outside a furnace therefrom. The mixer mixes the combustion gas and/ or steam with fuel. The fuel gas introducing device introduces the mixed fluid of the combustion gas, the steam and the fuel to the combustion area as fuel gas to mix the fuel gas with the air for combustion. The mixed fluid is introduced to the combustion area as a relatively large amount of fuel gas including lean fuel to be mixed with the air for combustion and thus generate a slow combustion reaction of the fuel gas in the combustion area. Thus, a flame property can be controlled by a fuel gas flow and the mixture of the fuel and the air for combustion can be more freely and assuredly controlled.
