  • Patent number: 5713202
    Abstract: A process of utilizing combustion products from fossil fuels to produce hydro-electric power through a process of allowing such products to displace water from a tank for operating a turbine or pelton wheel. The process allows hydro-electric power to be generated at a greatly increased efficiency. Preferably, two tanks are used to receive combustion products which exert pressure to displace the water. Alternatively, oxygen or air and a fossil fuel such as natural gas are introduced into the tank and combusted therein to generate the combustion products. The process allows existing power plants to generate additional power, and thus greatly increase the overall efficiency of the plant.

  • Patent number: 5551744
    Abstract: A windshield assembly for a curtain motor vehicle includes a windshield curtain, a furling casing, a power casing, a driving spring assembly and a revolving axle. The revolving axle, the speed of which is controlled, extends outside the power casing. The springs have opposite spiral directions and are connected to the ends of the revolving axle so as to rotate in the same direction. A link block is installed inside the spring and includes a link stick which extends outside an aperture of a sliding track within which the spring is located. The link sticks are connected to the bottom end of the windshield curtain. Thus, when the power casing is controlled to drive the revolving axle, the spring drives the link block to move upwards and downwards such that the windshield curtain is driven to move upwards or downwards.

  • Patent number: 5401480
    Abstract: A system is provided for converting flue gas pollutants to useful ammonium sulfate byproducts in an instantaneous gas phase reaction between a gaseous ammoniacal substance and the sulfur oxides in the flue gas. The system also removes other pollutants by converting them into other harmless byproducts and collects useful ammonium sulfate compounds.

  • Patent number: 5384106
    Abstract: The present invention specifically relates to a method and apparatus for removing pollutants of sulfur, nitrogen and metals from a fossil fuel fired power plant flue gas containing the same. In one embodiment, the process comprises introducing an ammoniacal substance into the flue gas in an amount sufficient to react with a substantial portion of the sulfur and nitrogen pollutants therein; cooling the flue gas by passing the gas past the exterior surfaces of a plurality of heat exchanger tubes which contain a cooling fluid therein and which are configured to define a serpentine passage in a downwardly descending manner at an angle of between about 10 to 60 degrees from the horizontal to condense ammonium sulfate or sulfite compounds from the flue gas; and collecting and removing the condensed compounds from the flue gas at several locations below the heat exchanger tubes as the flue gas passes thereby along the passage. In another embodiment, an apparatus for carrying out the process is disclosed.

  • Patent number: 5273727
    Abstract: A system is provided for converting flue gas pollutants to useful dry or concentrated ammonium bisulfite and ammonium bisulfate byproducts and other harmless byproducts, and for collecting the useful byproducts. The system also removes particulate material to maximize the desired reactions, and cools the flue gas in heat exchange with boiler feedwater.

  • Patent number: 4900403
    Abstract: An apparatus and process for separating a more volatile substance from a liquid in which it is dissolved by vacuum means. The apparatus has a perforated inner casing having a plurality of sub-stages which contain packing material to provide a tortuous path of interstices for the liquid to flow through; an outer casing surrounds the inner casing to define an evacuating space between the outer and inner casing and vacuum means to create a vacuum in the evacuating space which communicates with the sub-stages through the perforations in the inner casing. The vacuum means also acts to pull off the more volatile substance.

  • Patent number: 4876986
    Abstract: A compact and maintenance-free means and method of regenerating the sensible heat from flue gases of fossil fuel furnaces by heat exchange through two circular layers of rock beds rotating under two semi-circular mantles with the first mantle applying hot flue gases to the beds and the second withdrawing preheated ambient air needed for combustion by said furnaces. When used for power plant flue gas treatment, layers of acid-resistant pipes containing boiler feedwater are sandwiched between the two rock bed layers to usefully recover the heat units arising from moisture condensation. The enormous water of condensation collects flyash and sulphur dioxide thus removing these pollutants from the stack gases. The heavy rock beds rotate slowly beneath the fixed mantles in a circular, pan-shaped, steel vessel floating on and cooled by a circular pond of water. Friction of rotation is minimal and gas leakage principally prevented by liquid seals. When flue gas temperature rises, as above 600 degrees F.

  • Patent number: 4676299
    Abstract: A simple method to prevent air pollution from the particulate and gaseous pollutants from power plants, by recuperating the heat in the flue gases down to atmospheric temperature and pre-heat the air needed from combustion in the boilers. Most fly ash is removed at the face of the regenerators. Condensed moisture from the flue gases dissolves SO.sub.2 and forms a smog, with remaining fly ash particles acting as condensation nuclei, which are caught on the wetted surfaces within the regenerator, washed therefrom to vessels to settle out solids, and the liquid is then treated by vacuum to recover the dissolved SO.sub.2, which is compressed to liquid SO.sub.2 and stored in refrigerated tank cars, to be sold as a valuable byproduct. The bulk of the fly ash, which settles on the face of (45 degree) sloping "snow fences" built across the top of the pebble bed, slides like snow off of a sloping roof and into gutters with perforated false bottoms, up which flows a little gas and carry it to downspouts and bins.
