Abstract

PURPOSE: Provision of dampers in plural stages facilitates to make favorable furnace pressure control without augmenting power consumption even in low load drive condition.
CONSTITUTION: Dampers 6W8 are provided in plural stages, whose combination for opening degrees offers flow resistance proprtional to exhaust amount in order to control the furnace pressure practically constant. Opening/closing operation of these dampers 6W8 adds outputs of fuel gauges 3, 4 with use of a fuel adder 14, and furnace pressure measured by a pressure gauge 11 is let into a furnace pressure regulating gauge 13, then deviation to a settled pressure is brought out in collation with a settled pressure from a furnace pressure setter 12, input of the both is given to an exhaust gain arithmetic operating unit 15 to make arithmetic operation of exhaust amount from a furnace 1 and to perform respective opening/closing operations of damper operating units 16, 17, 18 predicated on the arithmetic operating results. This constitution facilitates to control the furnace pressure constant under every drive condition.
