Claim 1:
2. The fuel-reforming device according to claim 1, wherein the control means further stores high heating values of the reference fuel used in the combustion device, hydrogen, and ammonia, and, based on the ratio of the high heating value of the mixed gas with respect to the high heating value of the reference fuel, determines a flow rate fraction of a supply amount of the mixed gas with respect to the reference fuel on the basis of equation (3) and equation (4)

[Math 3]

Hm=HH×M+HA×(1−M)  Equation (3):

Wm=Hm/H0  Equation (4):

where Hm is the high heating value of the mixed gas, HH is the high heating value of hydrogen, HA is the high heating value of ammonia, H0 is the high heating value of the reference fuel, and Wm is a flow rate fraction by weight of the mixed gas with respect to the reference fuel,
further, the control means receives a fuel request speed of reference fuel from the combustion device, and determines a supply amount of the mixed gas to be supplied from the mixing tank to the combustion device on the basis of equation (5) and equation (6)

[Math 4]

mw=2×M+17×(1−M)  Equation (5):

Fm=(W0×Wm×1000)/mw×22.4  Equation (6):

where mw is a molecular weight of mixed fuel, W0 is the fuel request speed of reference fuel requested by the combustion device, and Fm is a supply amount of mixed gas to be supplied to the combustion device.
