  • Patent number: 7987677
    Abstract: Turbine exhaust steam, axially fed between counter-rotating radial flow disk turbines, separates into: (1) a radially inward flow of low enthalpy dry steam, and (2) a radially outward flow of high enthalpy steam, noncondensibles, and condensate. The radially inward flow goes to a conventional condenser. The radially outward flow loses enthalpy turning the disk turbines as it passes in the boundary layers against the disks, thus becoming low enthalpy dry steam, and the counter-rotation of the disks by impinging mass flow of condensate, high enthalpy steam, and noncondensibles sustains a cascade of dynamic vortex tubes in the shear layer between the boundary layers. The low enthalpy dry steam resulting from work being done flows into the condenser through the vortex cores of fractal turbulence. Condensate exits the periphery of the workspace, ready to be pumped back into the Rankine cycle.

  • Patent number: 6601391
    Abstract: A waste heat recovery system incorporates a contactor for counter current direct heat exchange between a non-condensible gas and a liquid, typically hot water. The water is from a heat source available at the site such as a solar source, a geothermal source, an industrial plant or the like. Hot mainly saturated gas exits from the contactor and drives a motor, typically a turbine. The turbine drive a work consuming device, normally an electric generator. A condenser/separator downstream from the turbine condenses the water vapor and separates the non-condensible gas from the liquid. The liquid from the condenser is preferably recycled or may be discarded.

  • Patent number: 6419448
    Abstract: A flow by-pass system is provided in a downward-discharging exhaust hood of a steam turbine to by-pass a small percentage of the total steam flow from the top portion of the exhaust hood to the vicinity of the condenser and in that way relieve excess pressure in the top portion incident to the more convoluted path of the main portion of steam passing from the top to the bottom and to decrease energy loss caused by friction and thus to improve turbine efficiency. The flow by-pass system includes by-pass conduits within the front portion of the exhaust hood extending from the top portion to the vicinity of the condenser.

  • Patent number: 6158221
    Abstract: A waste heat recovery system includes a chamber. A gas inlet and gas outlet direct the flow of hot gas from a waste heat source to and from the chamber. A working fluid inlet port and working fluid outlet port direct the flow of multicomponent working fluid to and from the chamber. A plurality of heating surfaces are disposed within the chamber. The heating surfaces are formed of tubes which transport the flow of multicomponent working fluid from the inlet port to the outlet port such that the flow of the hot gas from the gas inlet to the gas outlet transfers heat from the hot gas to the flow of multicomponent working fluid.

  • Patent number: 6145315
    Abstract: In a process for preheating and deaerating make-up water in a power generation plant by steam, the required make-up water is initially heated up to the saturation temperature without substantial deaeration and is subsequently deaerated. The steam used for heating and deaerating is expanded steam from a condenser, which steam is almost fully condensed during the heating of the make-up water and is recycled to the steam circulation of the power generation plant.

  • Patent number: 6079212
    Abstract: This invention relates to a gasification power generation process wherein a product gas A1 obtained by the gasification of coal or petroleum is used as the fuel of a gas turbine 4 for electric power generation, the process comprising the steps of dedusting product gas A1, introducing product gas A1 directly into gas turbine 4 as the fuel thereof to effect electric power generation, and subjecting the exhaust gas A2 discharged from gas turbine 4 to a gas purification treatment including at least desulfurization. This invention can provide a gasification power generation process which is more suitable for practical use from an economic point of view in that a high degree of exhaust gas purification and a marked improvement in thermal efficiency can be achieved and, moreover, the construction of the equipment for carrying out a gas purification treatment including desulfurization can be highly simplified.

  • Patent number: 5941073
    Abstract: For cleaning waste air loaded with organic pollutants one uses an adsorptive cleaning plant with a rotating cylindrical body containing an adsorbent through which waste air to be cleaned is passed for adsorption of the pollutants, hot air for desorption of the adsorbed pollutants and cooling air for cooling the desorption zone. Waste air with desorbed pollutants is supplied to an afterburning plant with a firebox. The hot air is formed by mixture of a part of the firebox air heated to 700 to C. produced in the firebox, with the heated cooling air passing out of the cylindrical body. The afterburning plant has two chambers connected via the firebox and filled with a heat-retaining packing, waste air with desorbed pollutants being supplied alternatingly to one of the chambers and clean air removed from the other chamber.

  • Patent number: 5548958
    Abstract: A waste heat recovery system is provided where a waste heat source is utilized to vaporize a working fluid which in turn powers a turbine to generate power in a heat engine. A heat exhanger is placed between a waste heat source in an industrial process and an evaporator. The evaporator is connected to a turbine chamber further connected to a multi-chambered condensation unit. Each chamber of the multi-chambered condensation unit has a valved inlet port and a valved outlet port. The valved inlet ports of each chamber of the multi-chambered condensation unit are connected to the turbine chamber outlet. The multi-chamber condensation unit includes a number of condensation chambers, each chamber including a plurality of computer controlled valves. The condesation chambers are sequentially evacuated causing the vapor to be drawn through the turbine and brought into the condensation chambers one at a time. A reservoir is provided which collects the condensate where it is pumped back to the evaporator.

  • Patent number: 5426941
    Abstract: A vapor condensation and liquid recovery system is provided where a turbine chamber is connected to a multi-chambered condensation unit. Each chamber of the condensation unit has a valved inlet port and a valved outlet port. The valved inlet ports of each chamber of the condensation unit are connected to the turbine chamber outlet. Each condensation chamber is provided with another valved port which is connected to a vacuum generating means. Each chamber is also provided with a further valved port connected to a purge pump. The valved outlet ports are connected to a fluid reservoir. All of the valves are opened and closed by valve control means such as a computer. The valve control means opens and closes the valved vacuum line, valved inlet ports, valved outlet ports, and valved purge line in a sequence to permit a condensable vapor to be continuously drawn through the turbine chamber where it rotates the turbine blades transferring energy from the vapor to the turbine shaft. As a result the vapor condenses.
