Abstract: A transmission system selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes a waste heat recovery (WHR) system, a brake assembly and a phase-change thermal heat storage system. The WHR system selectively circulates a WHR fluid in the transmission system. The brake assembly selectively couples a transmission output shaft to a drive axle. The brake assembly is configured to operate in a braking mode that retards relative rotation between the transmission output shaft and the drive axle while generating heat. The heat storage system includes a housing defining at least one cavity and a fluid transfer manifold. A phase-change material is disposed in the cavity that is configured to change phase during the braking mode. The WHR system circulates the WHR fluid through the fluid transfer manifold collecting braking heat to be used at a later time in the form of driveline power.

Abstract: A method for retrofitting a fossil-fueled power station is provided. The power station includes a multi-housing stream turbine with a carbon dioxide separation device. As per the method, a suction capability of the steam turbine is adapted for an operation of the carbon dioxide separation device to a process steam to be removed. The carbon dioxide separation device is connected via a process steam line to an intermediate superheating line. Further, an auxiliary condenser is connected to the carbon dioxide separation device. On failure or deliberate switching off of the carbon dioxide separation device surplus process steam is condensed in the auxiliary condenser.

Abstract: An electric power generating system employing a gas turbine (1) and a steam turbine (5) and a gasifier (9) supplying fuel-gas to the gas turbine (1) and to a steam generating fluidized bed combustor (37), the latter providing steam for the steam turbine (5). An auxiliary steam turbine (21), driving an electric generator (22), is also supplied by the circulating fluidized bed combustor steam generator (37). Since the gasifier (9) cannot be reversibly turned down easily, on a fall in load on the main steam turbine (5), the excess steam generated is diverted to the auxiliary steam generator (21) and the gasifier (9) kept running efficiently.
