Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a mixed combustion boiler system which can reduce an excessive air amount of a mixed combustion boiler while maintaining combustion stability thereof and thereby achieving highly efficient boiler operation.SOLUTION: A mixed combustion boiler system comprises: a mixed combustion boiler 70 which uses LNG and BOG as fuel gas; an LNG flowmeter 41 which measures a supply amount of the LNG to be supplied to the mixed combustion boiler 70; a BOG flowmeter 42 which measures the supply amount of the BOG to be supplied to the mixed combustion boiler 70; an air supplying device 60 which can supply combustion air to the mixed combustion boiler 70 by adjusting the supply amount of the combustion air; and a control section 90 which controls the supply amount of the combustion air to achieve a predetermined air-fuel ratio with respect to the supply amount of the fuel gas. The control section 90 corrects the supply amount of the combustion air in accordance with the supply amount of the BOG.SELECTED DRAWING: Figure 1
