Patent CA-2223129-A1 (CA)
Title: Method and roller grill for burning refuse
Inventor: ROBSON COLIN PETER
IPC: F23G5/44
Filed: 1996-03-18
Abstract: Enriching combustion air with oxygen when refuse is burned is a known procedure. Even low-level enrichment causes a considerable rise in temperature in the combustion chamber. In order to limit that rise in temperature, it has been the practice to spray wet sludge into the combustion chamber as an extinguishing agent. This makes it possible to enrich the air to any desired degree, but requires a very large quantity of oxygen, thus considerably increasing operating costs. According to the present invention, the additional oxygen-enriched air is blown from air boxes (7) into the refuse layer, independently of the primary air, only within narrow zones extending transversely, in a roller grill hearth (1) within the confines of the roller gussets between any two adjacent rollers (5). In this way, an intense fire is fanned and ignites the overlying refuse (8). The combustion efficiency is hereby considerably improved at little cost and without any unwanted rise in temperature.

Patent CA-2224425-A1 (CA)
Inventor: JACOB STEVEN D
IPC: B08B15/02
Filed: 1997-12-10
Abstract: A fume hood controller includes detection apparatus for detecting the presence of objects within the fume hood and reduces the flow through the fume hood if there are no objects within the hood, thereby conserving energy costs associated with conditioning supply air to the room where the fume hood is located. The controller also adjusts flow as a function of the presence and also the location of objects that are detected within the fume hood. Since there is a smaller likelihood of fume spillage when the objects are located more deeply within the fume hood, theflow can be reduced in such a situation compared to that which would be required if the objects are located closer to the sash.

Title: Bioreactor process for the continuous removal of organic compounds from a vapor phase process stream
Inventor: SHEPHERD ROBERT DONALD JR
IPC: B01D53/84
Filed: 1996-11-22
Abstract: The present invention provides a method for treating volatile hazardous air pollutant (VHAP) and volatile organic compound (VOC) waste products from gas streams. The system disclosed herein employs microporous hydrophilic membranes (10) to remove VHAPs/VOCs from a gas stream (40) into an oleophilic stripping fluid (44). The stripping fluid (44) is directed into a separate biomembrane reactor (20) wherein the VHAPs/VOCs are transferred across a second microporous hydrophobic membrane into an aqueous nutrient medium (120), where the extracted VHAPs/VOCs are degraded by microorganisms residing on the surface of the membrane. VHAPs/VOCs are degraded to carbon dioxide, water, and cell debris. The disclosed system uncouples biotreatment from waste generation, such that operation of the biotreatment unit (20) can be continuous and optimized independently of plant work schedules or fluctuations in pollutant concentrations entering the system.
