Title:
BOILER SYSTEM
Document Type and Number:
Japanese Patent JP2016020789
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a boiler system capable of effectively suppressing the influence of a variation in a mass flow generated by a temperature variation on an air ratio, and stably and efficiently exerting a combustion control.SOLUTION: A boiler system 1 comprises: a storage unit 72 storing a flow volume of combustion air and a value of a degree of opening of a flow regulating valve 56 while making the flow volume correspond to the value of the degree of opening; a degree-of-opening setting unit 91 setting a value of a degree of opening on the basis of the flow volume of the combustion air detected by an air differential pressure sensor 33; a temperature correction unit 92 correcting the value of the degree of opening on the basis of a temperature detected by a fuel gas temperature sensor 57; and a degree-of-opening control unit 95 controlling the degree of opening of the flow regulating valve 56 on the basis of the corrected value of the degree of opening corrected by the temperature correction unit 92.SELECTED DRAWING: Figure 1
