動台数制御装置。[Scope of Claim for Utility Model Registration] A plurality of boilers 1 that perform combustion control in three positions: high combustion state, low combustion state, and stop state are installed, and a common steam header 2 is provided for these boilers. In the configuration, a number controller 4 is provided, which converts the internal pressure into an electric signal using a pressure detector 3 and extracts it, and uses the signal to combust and stop the required number of boilers according to the load amount, the steam in the steam header In addition to providing a pressure gradient discrimination section 5 that discriminates whether the pressure is rising or falling, when the steam pressure falls, if there is a boiler in a low combustion state, that boiler is shifted to a high combustion state, and if there is no boiler in a low combustion state, the boiler is shifted to a high combustion state. Move a new boiler to a low combustion state, and when the steam pressure increases, if there is a boiler in a high combustion state, move that boiler to a low combustion state, and if there is no boiler in a high combustion state, change the boiler to a low combustion state. A three-position control type automatic boiler number control device comprising a control section 6 that determines the order of combustion and shutdown of the boilers so as to stop the boilers.
