Title:
BOILER SYSTEM
Document Type and Number:
Japanese Patent JP2014228180
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a boiler system capable of enhancing pressure stability in the whole system when allowing a load factor of a boiler to follow with respect to load fluctuation.SOLUTION: A boiler system 1 includes a boiler group 2 including a plurality of boilers 20 and a control unit 4 for controlling a combustion state of the boiler group 2. At the plurality of boilers 20, a plurality of operation zones are set individually corresponding to a predetermined load factor range. The control unit 4 includes: a first increase selection unit 451 for selecting a boiler located in a load factor other than the lower limit value or the upper limit value in the operation zone as a boiler in which a steam amount is increased, when a necessary evaporation amount is larger than an output evaporation amount; a first decrease selection unit 461 for selecting a boiler located in the load factor other than the lower limit value or the upper limit value in the operation zone as a boiler in which a steam amount is decreased, when the necessary evaporation amount is smaller than the output evaporation amount; and an output control unit 48 for increasing or decreasing the steam amount of the selected boiler.
