Abstract
Official abstract text for this publication.
A boiler system equipped with a boiler group mixedly provided with a step value control boiler and a proportional control boiler. A boiler number control device is configured to control the number of boilers in the boiler group, and includes an output controller configured to control a combustion state of the boiler group so as to cause the proportional control boiler to output steam equivalent to a required steam flow according to a required load, and an output switcher configured to switch, under a condition that a steam flow outputted from the proportional control boiler reaches a predetermined steam flow exceeding a steam flow at a possible combustion point of the step value control boiler, output of the steam flow at the combustion point from the proportional control boiler to the step value control boiler.
First claim
Opening claim text (preview).
1 . A boiler system comprising a boiler group including a step value control boiler configured to combust at a plurality of stepwise combustion points, and a proportional control boiler configured to combust at a continuously changed combustion rate, and a controller configured to control a combustion state of the boiler group in accordance with a required load, wherein the controller includes an output controller configured to control the combustion state of the boiler group to cause the proportional control boiler to output steam equivalent to a required steam flow according to the required load, and an output switcher configured to switch, under a condition that a steam flow outputted from the proportional control boiler reaches a predetermined steam flow exceeding a steam flow at a possible combustion point of the step value control boiler, output of the steam flow at the combustion point from the proportional control boiler to the step value control boiler. 2 . The boiler system according to claim 1 , wherein the predetermined steam flow is more than the steam flow at the combustion point by a minimum steam flow outputtable from the proportional control boiler. 3 . The boiler system according to claim 1 , wherein the predetermined steam flow is more than the steam flow at the combustion point by a steam flow corresponding to a lower limit value within an ecological operation zone in which boiler efficiency of the proportional control boiler is higher than a predetermined threshold. 4 . The boiler system according to claim 1 , wherein, even when the step value control boiler combusts at a combustion point with maximum efficiency and a steam flow outputted from the proportional control boiler reaches the predetermined steam flow, the output switcher keeps output from the proportional control boiler.
