POLLUTION NEUTRALIZING WOODBURNING STOVE 4901654 Claude Berlaimont, Couvin, Belgium assigned to Fonderies Du Lion S A
DEODORIZATION AND CLEANING OF MEDIUM TEMPERATURE WET OFF-GASES DERIVED FROM BURNING OF WET WASTE SLUDGE
This invention concerns a solid fuel stove, in particular a wood stove fitted with a device capable of neutralizing the polluting elements of burnt gasses and that comprises, in a conventional manner, a chamber of combustion formed by vertical walls and that extends between a grate and the burnt gas flue, characterized in that the aforesaid device (12) consists of a postcombustion chamber that extends obliquely through the chamber of combustion (I) and that forms a compulsory passage heated to a high temperature level by the fuel, with the burnt gasses circulating in this device from the bottom to the top and from one wall of the hearth to the opposite wall.
Medium temperature (500 degrees F.-II00 degrees F.) wet off-gases from the final drying zone of counterflow incineration of waste sludge are scrubbed and cooled before heating to final high temperature in an afterburner and the resulting hot dry gases are used to preheat the scrubbed and cooled gases prior to entry of said gases into the afterburner.

PRESSURIZED WET COMBUSTION OF WASTES IN THE VAPOR PHASE
APPARATUS AND METHOD OF REDUCING POLLUTION FOR TIRE BUFFING EQUIPMENT
Norman L Dickinson assigned to Dipac Associates Liquid wastes and solid wastes, which can be put into slurry form, have combustible constituents burned from t h e m a t supercritical temperature and subcritical pressure, with respect to water, resulting in purified water and, with the more concentrated wastes, recovery of valuable energy. Pressure makes possible the recovery of latent heat so that the dry heating value of the waste is made available. Consequently, relatively
