Abstract

PURPOSE:To reduce a variation in heat producing heat exchanging operation by a method wherein a volume of fuel is controlled by a low selector means for selecting a lower output from the first calculator for calculating a required volume of fuel and the second calculator for calculating a limiting volume of fuel for producing black smoke. CONSTITUTION:Control system 1 for a volume of fuel for controlling a volume of fuel in response to a fuel load and a volume of air A is composed of a first calculator 1A for calculating a required volume of fuel in response to a voltage E corresponding to the load of fuel, volume of air A, second calculator 1B for calculating a limiting volume of fuel Fu for producing a black smoke in response to a corresponding voltage VAO, low selector 1C for selectively producing a lower output of the first and second calculators, and a solenoid-type proportional valve (+) acting as a fuel control means for controlling a volume of fuel in response to an output of the low selector. Electrical control system 2 controls a volume of air in response to a load of combustion. For example, when a volume of molten metal is increased, the volume of fuel is rapidly increased up to the producing limit of the black smoke and then decreases an under-shoot of the output of the heat exchanger.
