Abstract
PURPOSE:To restrict occurrence of soot when throuttling a two-stage combustion burner and reduce the quantity of NOX in the exhaust gas by increasing a ratio of primary air to primary plus secondary airs as the fuel combustion amount is decreased. CONSTITUTION:A temperature in a furnace is measured by a thermocouple 21. The output from the thermocouple 21 is applied through a thermostatic control meter 22 to a flowrate control meter 23, a flow meter 24 and a control valve 25 to thus control fuel supplied to a two-stage combustion burner 27 through a fuel circuit 26. The output from the flow meter 24 is applied to function converters 29a, 29b in primary and secondary air circuits 28a, 28b, respectively. Air supply amount signals from the converters 29a, 29b are applied to flowrate control meters 31a, 31b, respectively, which thereupon compares the signals with flowrate signals from flow meters 32a, 32b to thus drive control valves 33a, 33b, respectively. In this case the air supplied through the circuits 28a, 28b to the burner 27 is so controlled that a ratio of primary air to primary puls secondary airs increases as the fuel combustion amount is decreased.
