1. A fuel-reforming device to supply a fuel gas containing ammonia and hydrogen to a combustion device, the fuel-reforming device comprising:
an ammonia tank;
a reformer configured to reform ammonia and generate high-concentration hydrogen gas;
a mixing tank configured to temporarily store a mixed gas and supply the mixed gas as a fuel gas to the combustion device, the mixed gas being a mixture of ammonia supplied from the ammonia tank via a first ammonia supply path and the high-concentration hydrogen gas generated in the reformer by reforming ammonia supplied from the ammonia tank to the reformer via a second ammonia supply path separated from the first ammonia supply path; and
a controller configured to control respective supply amounts of the ammonia and the high-concentration hydrogen gas to be supplied to the mixing tank, and to control an amount of the mixed gas to be delivered to the combustion device, based on values of a combustion rate and a high heating value requested by the combustion device.
