  • Low temperature destruction of toxics in pollutant air streams
    Patent number: 5476640
    Abstract: Low temperature apparatus for the destruction of low volume time varying organic air toxins in air streams utilizing non-catalytic glass beads in parallel conduits heated by hot gas flow around the conduits and flowing the air stream through the conduits and controlling the hot gas flow in response to toxin levels in the air stream.
    Type: Grant
    Filed: August 25, 1994
    Date of Patent: December 19, 1995
    Assignee: The United States of America as represented by the Administrator of the U.S. Environmental Protection Agency
    Inventors: James H. Abbott, Dennis C. Drehmel, Geddes H. Ramsey
  • Fireplace with destruction of products of incomplete combustion enhanced by a gaseous-fueled pilot burner
    Patent number: 5322052
    Abstract: Particulate emissions from a wood fire in a fireplace having a baffle for preventing the direct flow of fluid into the flue from the wood fire are reduced by locating a hydrocarbon gas pilot source in proximity to the baffle. Ignited gas from the pilot combines particulate emissions from the wood fire while they are in the fireplace and before they reach the flue. Air from outside of the fireplace is supplied into proximity with ignited pilot gas so the outside air and the ignited pilot gas mix. A flame sensor for the pilot controls the flow of gas to the pilot source and ignition of the pilot source.

  • Corona destruction of volatile organic compounds and toxics
    Patent number: 5236672
    Abstract: Apparatus and method for controlling volatile organic compounds and air toxics in a contaminated fluid flow through use of an excited species flow generated and introduced into the contaminated fluid flow to convert the contaminants into non-toxic compounds. Tungsten electrodes and an alternating current are used in the excited species generator.
    Type: Grant
    Filed: December 18, 1991
    Date of Patent: August 17, 1993
    Assignee: The United States of America as represented by the United States Environmental Protection Agency
    Inventors: Carlos M. Nunez, Geddes H. Ramsey, Wade H. Ponder, James H. Abbott
  • Single chamber wood stove including gaseous hydrocarbon supply
    Patent number: 5179933
    Abstract: A single chamber wood stove has primary and secondary combustion zones in direct fluid flow communication with each other. Air from outside the stove is supplied to the primary and secondary combustion zones. Gaseous hydrocarbon fuel from a source located outside the stove is selectively supplied to the secondary combustion zone and is ignited by a glow plug in the secondary combustion zone in response to a signal derived by a temperature detector in the secondary zone. The gaseous hydrocarbon fuel flows to the secondary combustion zone at a rate in the range of about 0.25 to 3 cubic feet per hour. The fuel is supplied to the secondary zone when the secondary zone temperature is above carbon monoxide ignition temperature.
