<P>PROBLEM TO BE SOLVED: To suppress variation in RT (Radiant Tube) surface temperature. <P>SOLUTION: A control part measures a temperature of a combustion chamber 3c in which fuel gas is combusted and controls a flow rate of combustion air supplied to the combustion chamber 3c based upon the measured temperature of the combustion chamber 3c. Consequently, a variation in RT surface temperature can be suppressed. Further, the control part 103 measures a surface temperature of a recuperator 4 and controls the flow rate of combustion air supplied to the combustion chamber 3c based upon the measured surface temperature of the recuperator 4. Consequently, the variation in RT surface temperature can be further suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
