Abstract

PURPOSE:To keep a high combustion efficiency even under an excessive condition such as a changing of load, etc., and to reduce generation of pollution making substances by a method wherein an excessive rate of air is always controlled to show a value within a range of predetermined upper limit and lower limit in a natural aeration type combustion control device for various heating furnaces. CONSTITUTION:A value calculated by multiplying a coefficient (1+K1) to an allowable fuel flow rate signal Ffp got through an output signal P of an inter-furnace pressure gauge 17 is defined as an upper limit value B, and a value multiplied by a coefficient (1-K2) to the allowable fuel flow rate signal is defined as a lower limit value C, and these two values are applied in respect to a fuel flow rate command signal A received from a temperature adjusting means 9. This controlled signal A is defined as a set value and fuel flow rate controlling means 12 may control a fuel flow rate Ff. In turn, as regards a full flow rate of discharged gas, a value multiplied by a coefficient (1-K3) to an output of a fuel flow rate meter 5 is defined as a lower limit E and a value multiplied by a coefficient (1+K4) is defined as an upper limit G, and these values are added to the signal A. A total flow rate signal of discharged gas is calculated from this limited fuel flow rate command signal H, a differential pressure required for discharging a total amount of discharged gas is calculated and an inter-furnace pressure is controlled with this differential pressure being applied as an inter-furnace pressure set value Ps.
