To provide a combined cycle plant, a control device thereof, and a steam turbine startup method that are aimed at improving the operability of a combined cycle plant by allowing a quick change of the output. A combined cycle plant is provided with: a gas turbine having a compressor, a combustor, and a turbine; a supplementary firing burner that raises the temperature of exhaust gas of the gas turbine; a heat recovery steam generator that generates steam using exhaust heat of the exhaust gas; a steam turbine that is driven by steam generated by the heat recovery steam generator; and a control device that changes both an output of the combustor and an output of the supplementary firing burner when an output of the combined cycle plant is to be changed.

A precombustion chamber igniter with a retractable electric glow plug and a cold start control method for a methanol engine are provided. The precombustion chamber igniter includes a fuel injector, a spark plug, and an electric glow plug. The electric glow plug is retractable and has two working positions, at a first position, a heating segment is wholly located in an injection chamber to provide heat energy for the injection chamber, and at a second position, the heating segment is partially located in the injection chamber and passes through a first through hole, and the rest of the heating segment is located in a main combustion chamber of an engine, to provide heat energy for the injection chamber and the main combustion chamber. In a cold start stage of the engine, the heating segment of the electric glow plug is controlled to be located at the second position.

A method of starting a compression ignition engine is provided. The method comprises using a glow plug of the compression ignition engine to perform a warm up routine to preheat the compression ignition engine. During the warm up routine, a fuel rack actuator of the fuel rack is actuated which controls the quantity of fuel to be injected into the compression ignition engine such that the fuel rack is in a start-up fuel injection position by the end of the warm up routine. Following the end of the warm up routine, the compression ignition engine is cranked until the compression ignition engine starts, wherein the fuel rack actuator maintains the start-up fuel injection position of the fuel rack until the compression ignition engine has started.

A process of quickly starting a hydrogen generator from cold conditions. The generator, which converts a fuel and an oxidant under catalytic partial oxidation conditions into a mixture of hydrogen and carbon monoxide, is intended for onboard integration with an internal combustion engine (ICE) of a transportation vehicle. Fast start of the hydrogen generator allows for rapid hydrogen augmentation of the ICE with the advantages of a more stable combustion and a reduction in hydrocarbon and NOx emissions.
