摘要： An engine system includes an engine having a combustion chamber, an intake gas passage through which air to be supplied to the combustion chamber flows, an exhaust gas passage through which exhaust gas generated from the combustion chamber flows, a reformer configured to reform the fuel to generate a reformed gas containing hydrogen, a gas supply passage through which air to be supplied to the reformer flows, a bypass passage connected to the gas supply passage and the exhaust gas passage so as to bypass the reformer and through which the fuel having passed through the reformer is circulated to an upstream of the reformer, and a switching valve switched between a normal position that does not allow the fuel having passed through the reformer to flow to the bypass passage and a circulating position that allows the fuel having passed through the reformer to flow to the bypass passage.

摘要： A combustor includes a combustion pipe, a gas introduction pipe, and an igniter. The gas introduction pipe is connected at one end of the gas introduction pipe to the combustion pipe, and the one end has a gas outlet through which ammonia and oxidized gas flow to the combustion pipe. The gas introduction pipe protrudes toward an inside of the combustion pipe through an insertion hole of the combustion pipe in a tangential direction to an inner peripheral surface of the combustion pipe so that the gas outlet is accommodated in the combustion pipe. The gas introduction pipe has a cross-sectional area that is defined so that mixed gas of the ammonia and the oxidized gas flows to the combustion pipe through the gas outlet at a flow velocity of 3 m/s to 25 m/s relative to a flow rate of the mixed gas.

摘要： A combustor includes: a housing having an annular shape of which one end side is open and of which the other end side is closed; at least one introduction portion that introduces a fuel and an oxidizing gas into the housing to generate a tubular flow; and an ignition unit that ignites the fuel introduced into the housing. The ignition unit includes a discharge electrode and a ground electrode. A space that the fuel and the oxidizing gas reach is provided between the discharge electrode and the ground electrode.

摘要： An engine system includes: an ammonia engine; a reforming device that has a reforming catalyst for cracking ammonia gas into hydrogen and configured to reform ammonia gas to generate reformed gas containing hydrogen; and a control unit. The control unit includes: a purge controller configured to control a reforming injector so as to be closed and control a reforming throttle valve so as to be opened, after an ignition switch gives an instruction of a stop of the ammonia engine; and an engine stop controller configured to control main injectors so as to be closed, after the ignition switch gives the instruction of the stop of the ammonia engine.
