Document Type and Number:
WIPO Patent Application WO/2015/025729
Kind Code:
A1
Abstract:
A boiler system (1) equipped with a boiler group (2) in which step value control boilers (20A) and proportional control boilers (20B) are intermixed, wherein a unit number control device (3), which controls the number of boilers in the boiler group (2), is equipped with: an output control unit (41), which controls the combustion state of the boiler group (2) such that steam equivalent to the required amount of steam in accordance with the required load is output from the proportional control boilers (20B); and an output switching unit (42) which, if the amount of steam output from the proportional control boilers (20B) reaches a prescribed amount of steam exceeding the amount of steam corresponding to a combustion position achievable in the step value control boilers (20A), switches the output of the amount of steam corresponding to that combustion position from the proportional control boilers (20B) to the step value control boilers (20A).
