CONTROLLER AND BOILER SYSTEM

摘要

A controller includes a program for controlling a group of boilers having boilers with a plurality of staged combustion positions. The program is arranged to control the boilers and the combustion positions such that a total load following evaporation amount obtained by summing up load following evaporation amounts of the respective boilers comprising the group of boilers becomes equal to or more than a setup load following evaporation amount which is an evaporation amount that the group of boilers is to follow.
