Abstract: An integrated coal-fired gas turbine power plant includes a hydraulic compressor for providing pressurized air to a coal combustion system and cooling air to the gas turbine. The power plant may further include a regenerator between the compressor and the combustion system, and a gas cleanup segment between the combustion system and the gas turbine.

Abstract: Heat generated in an atmospheric coal combustion process is recovered by air compressed in a hydraulic compressor and passed through air heaters in an associated coal combustor and through a heat exchanger means in thermal contact with the exhaust flow of a gas turbine to thereby provide a heated compressed motive fluid for the production of useful work in the turbine.

Abstract: A process is described for both (i) quenching a fuel gas mixture including at least one gaseous hydrocarbon foulant (described more particularly herein) and (ii) removing at least a portion of the foulant without substantial formation of mist thereof in the gas mixture. The process includes contacting a flow of the gas mixture with a liquid jet spray of large droplets of a coolant mixture comprising liquid water and viscous liquid hydrocarbon. The contact is maintained for a sufficient period of time such that at least a portion of the foulant is liquefied and collected on the droplets. The droplets having foulant thus deposited thereon are removed from the treated gas mixture in a separation zone.

Abstract: A process for separating particulate matter from a contaminated gaseous medium includes employing a swirling substantially contaminant-free gaseous medium between a zone for introducing the contaminated medium into a cyclonic separator zone and a product gas exhaust zone which extends into the separation zone. Apparatus suitable for carrying out the process is also described.

Abstract: By maintaining a circumferentially-continuous, rotating film of water on the housing of a water-cooled gas turbine, kinetic energy imparted to the cooling water droplets by rotational velocity of the turbine bucket shrouds is partially absorbed in the film when struck by the droplets, thereby reducing erosive effects on the turbine housing resulting from droplets slamming the housing.

Abstract: Gas-fluidized ground coal, and coal dust slurried with fuel oil, are supplied to a reverse flow cyclone combustor which provides the functions of combustion and particulate removal. Coal dust borne by the fluidizing gas is passed through a cyclone scrubber utilizing fuel oil, and the resulting slurry is introduced into the combustor adjacent the inner surface of the combustor wall. Only the finest coal dust is employed in the slurry, to minimize oil consumption. Separative performance of the combustor is enhanced by introducing combustion air centrally adjacent the combustor outlet and gas-borne ground coal directly onto the cyclone walls.

Abstract: In a gas-cooled generator or other dynamoelectric machine, the windings mounted in slots in the rotor are provided with a plurality of passages for the flow of cooling gas from the gap between the rotor and stator, diagonally down through the windings, then diagonally back up to the gap. In contrast to the prior art, wherein two ascending passages join at a shared outlet duct to the gap, the separation is maintained herein, by providing a completely separate outlet duct for each ascending passage, for improving the flow of cooling gas through the rotor and into the gap.
