Abstract: PURPOSE:To heat or cool uniformly the gas in a furnace by introducing and mixing the gas in high temperatures existing in the upper space of the furnace inside through a circulation passage for the furnace inside gas opening at the upper end of the inner wall of the furnace, into the combustion gas ejecting from a burner and then ejecting the mixed gases into the furnace inside. CONSTITUTION:Combustion gas at a high speed ejecting from a high speed burner 1 proceeds deeply into a furnace chamber 7 through the lower opening 12 as shown in an arrow (a) and then is mixed with the gas in the chamber 7 and a circulation stream is produced in the chamber 7 as shown in an arrow (b). On this occasion, as low pressure condition is formed by the combustion gas at high speed ejecting from the burner 1 at the lower part between the walls 10 and the inner wall 11, the gas in the upper part of the chamber 7 is sucked in the lower part of a recirculation passage 14 between the walls 10 and 11 through the upper opening 13. In this way, reflux gas in the furnace and ejecting gas from the burner are mixed at the outlet of the burner 1 and the gas of which temp. is nearly the average temp. in the furnace is ejected into the chamber 7 through the opening 12 and hereby, the gas in the furnace is quickly equalized in temp. and is uniformly heated or cooled.
