FUEL-REFORMING DEVICE AND FUEL-REFORMING METHOD

WIPO Patent Application WO/2020/217998

A1

Provided is a fuel-reforming device comprising: an ammonia tank (4); a reformer (5) for reforming ammonia and generating high-concentration hydrogen gas having a hydrogen content of at least 99%; a mixing tank (7) for mixing ammonia and hydrogen for temporary storage; and a control means (10) for controlling the respective supply amounts of ammonia and high-concentration hydrogen gas that are supplied to the mixing tank (7).　The control means (10) calculates the combustion rate coefficient C of mixed gas with respect to a reference fuel on the basis of equation (1).　Equation (1): S0=SH×C＋SA×(1-C).　In equation (1), S0 is the combustion rate of the reference fuel, SH is the combustion rate of hydrogen, SA is the combustion rate of ammonia, and C is the combustion rate coefficient of mixed gas.　In addition, on the basis of equation (2), the control means (10) determines the volume fractions of ammonia and hydrogen that are supplied to the mixing tank.　Equation (2): C=1-exp(-A×MB).　In equation (2), M is the volume fraction of hydrogen in mixed gas, and A and B are constants.
