Patent number: 5713202Abstract: 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.Type: GrantFiled: August 21, 1996Date of Patent: February 3, 1998Assignee: Energy Conservation Partnership, Ltd.Inventor: Arthur F.

Patent number: 5061467Abstract: Improved methods and apparatus for removing unwanted pollutants from flue gases are disclosed. A sequence of at least three vertical beds of particulates is disposed in the flue gas exhaust duct. A first bed comprises boiler ash or sand. Lime in the fly ash and sulfuric acid and water in the flue gas react with the particulates to form gypsum, removing the fly ash from the flue gas. In the second bed, the remaining sulfuric acid is condensed and removed on a further bed of boiler ash. In the third bed, a catalyst, typically an activated aluminous particulate with an alkali coating thereon, provided by adding ammonia to the flue gas stream, condenses out the remaining sulphur dioxide, which can then be removed from the catalyst particles in a regenerative step. A scrubber embodying these principles is readily retrofittable to pre-existing power plants burning sulphur-containing coal.Type: GrantFiled: July 6, 1990Date of Patent: October 29, 1991Assignee: ROM Industries CorporationInventors: Arthur F.

Patent number: 4876986Abstract: 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.Type: GrantFiled: September 11, 1987Date of Patent: October 31, 1989Assignee: Energy Conservation Partnership, Ltd.Inventor: Arthur F. Johnson

Patent number: 4676299Abstract: 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.Type: GrantFiled: April 1, 1985Date of Patent: June 30, 1987Assignee: Energy Conservation Partnership Ltd.Inventor: Arthur F.
