Abstract: <P>PROBLEM TO BE SOLVED: To provide a furnace capable of uniformizing temperatures at high temperatures, increasing a working efficiency, and reducing a fuel cost and a production cost by forming a compact and stable hot heat treatment combustion gas area in an area apart from a wall surface forming a combustion chamber.  <P>SOLUTION: The air/fuel pre-mixture 14 flows from a side wall inflow port 13 opening in a cylindrical side wall face 12 into a cylindrical combustion chamber 11 surrounded by the cylindrical side wall face 12 and having both end parts 16 and 16 opening to the outside, and a swirl flow is produced to form a continuous flame face 15 generally symmetrical with respect to the center axis thereof. The thermal treatment of a long treated material 19 can be performed by the hot and constant temperature burned gas area 18 formed inside the continuous flame face 15. Since the cylindrical side wall face 12 is not overheated since it is covered by the rather low temperature pre-mixture 14, the burned gas area 18 can be further heated, and the lightweight and small-sized furnace can be easily manufactured by using an inexpensive metal other than expensive heat resistant materials.  <P>COPYRIGHT: (C)2004,JPO
