Abstract: A liquid-vapor separator for two-phase fluids in general and specifically a steam-water separator in a steam drum of a steam generator includes axial or radial spinner blades to create a centrifugal motion which causes liquid to be forced outward against the outer wall and the vapor to be concentrated in the center. Conical extraction skimmers systematically extract and discharge the liquid outwardly and downwardly through the side walls such that it impinges on an optional discharge screen surrounding the skimmers.

The conical extraction skimmers include an outwardly protruding rim portion which forms an enlarged annular chamber between the rim and the underlying conical extraction skimmer. This forms a converging-diverging flow path out between skimmer sections and an outwardly extending ring forms a tortuous path.

Abstract: An air-cleaning, heat-exchange apparatus includes a main housing portion connected by means of an air inlet fan to the kitchen exhaust stack of a restaurant. The apparatus includes a plurality of heat exchangers through which a heat-absorptive fluid is circulated, simultaneously, by means of a suitable fluid pump. These heat exchangers absorb heat from the hot exhaust gas, out of the exhaust stack of the restaurant, which flows over and through these heat exchangers and transfers this heat to the circulating fluid which communicates with remote heat exchangers. These remote heat exchangers further transfer this heat to a stream of air, such as that from a cold-air return duct for supplementing the conventional heating system of the restaurant. Due to the fact that such hot exhaust gas is heavily grease laden, grease will be deposited on virtually all internal surfaces of the apparatus which this exhaust gas contacts.

Abstract: This invention relates to water removal or separator which can remove droplets of water suspended in the air as mist, and can separate the mist from the air to change and to transform "wet-air" into "dry-air." More particularly this invention relates to such devices which have a housing with baffles. The "wet-air" enters the housing from an inlet or orifice and strikes the baffles, and through the action of evaporation and surface friction the air sheds the water droplets onto the baffles. The water thus condensed on the baffles then drops and collects in the floor of the housing wherefrom it may be drained to the atmosphere through a small opening or an exhaust nozzle.
