Claims

[Scope of utility model registration request]

(1) A plurality of boilers that perform three-position control of high combustion amount, low combustion amount, and combustion stop are installed, and a pressure regulator 2 that monitors the load status is installed in the steam header 1 that is common to each boiler.
Automatic boiler number control system consisting of a number controller main body 3 that sequentially shifts the required number of boilers to combustion according to the load amount, and if there is a load change, shifts and stops the boilers in accordance with the load change. In the device, the number control main body 3 is configured to sequentially increase the number of boilers that perform low combustion as the load increases, and as the load further increases, the number of boilers changes from low combustion to high combustion according to the load. An automatic number control device for boilers, characterized in that the number controller main body 3 determines the starting order A of the boilers so that the boilers start up order A.

(2) Number of Boilers 11 The starting order of the main bodies 3 is such that the number of boilers that perform low combustion is increased in accordance with the increase in load, and as the load increases further, the low combustion is increased in accordance with the load. Depending on the start order A determined to shift to a high combustion rate and the load, one boiler is made to transition from a low combustion rate to a high combustion rate, and as the load increases further, the other boilers are switched to a low combustion rate. The automatic boiler number control device according to claim 1, which is characterized in that it has a configuration in which a starting order B is determined so as to increase the combustion rate and further shift to a high combustion rate.
