PROBLEM TO BE SOLVED: To provide an in-furnace agitation method, agitation device and a furnace capable of agitating the interior of the furnace without causing an increase in the volume of gas in the furnace and agitating the gas from a middle temperature range to a high temperature range. SOLUTION: There are provided a circulation fan 5, a change over valve 6 which reverses the circulating direction of gas, a pair of heat accumulators 7 and 8 in a gas circulation line 4 which sucks up an in-furnace gas and then blows the gas into the furnace and the in-furnace gas is sucked up by way of the heat accumulators and then the in-furnace gas is blown into the furnace by way of the paired heat accumulators. This process is repeated while reversing the circulating direction of the gas. |
