を特徴とするボイラーの自動台数制御装置。 In a multi-can installation system, a pressure regulator is installed that outputs a signal according to the internal pressure of the steam header, and in response to the signal from the pressure regulator, a low combustion signal generating section that directs the boiler to a low combustion state and a low combustion signal generator that directs the boiler to a low combustion state are installed. An automatic number control device for boilers, characterized in that a high combustion signal generation section for producing a high combustion state is set, and combustion order setting switches having a required number of switching contacts are arranged in the same number as the number of boilers.
