Patent Searching and Data

Document Type and Number:
Japanese Patent JP2000240908
Kind Code:

To prevent fire insulating tiles being lined on a combustion chamber from being burnt by providing a cylindrical rectifying member which makes a combustion gas advance straight in the combustion chamber until the combustion gas being jetted from a nozzle is discharged into a furnace from the combustion chamber for a heavy fuel oil burner.

A gas 6 being jetted from a burner gun 3 is immediately combusted with air 2 in a nozzle 4 so that scales may not be generated on a tube body which is an objective to be heated, and a combustion gas of a high temperature is formed, and the combustion gas is made to advance straight at least until being discharged into a furnace from a combustion chamber 5. In concrete, at the tip end of the nozzle 4, a cylindrical rectifying member 7 of which the length is equivalent to a distance from the combustion chamber 5 for a heavy fuel oil burner to a point wherein the combustion gas goes through, and which suppresses the stream of the combustion gas in the radial direction, is arranged. Therefore, even when the combustion chamber 5 is the same as one which is used for a heavy fuel oil burner, the high temperature gas does not apply a large thermal burden to the internal wall of the combustion chamber 5, and also, the generation of scales on the tube body can be reduced as well.
