Abstract: A positive pressure heat pump system and method wherein a heat pump is housed within a cabinet having an outdoor blower section and a segregated indoor blower section. The heat pump condensing coil is positioned within the outdoor air blower section and a cooling coil is positioned within the indoor blower section. A variable angle vane is operable to divert pressurized and heated outdoor air, downstream of the condensing coil, from the outdoor air blower section into the indoor air blower section, upstream of the cooling coil, so that cooled and pressurized air is recycled into the interior of a building to maintain a positive pressure within the building relative to the surrounding ambient environment.

Abstract: A coincineration process whereby sewage sludge or other toxic liquid chemical waste is incinerated with a supplemental fuel such as municipal refuse, coal, sawdust, tire chips and the like involves introducing the sewage sludge into the incineration zone by means of a pressure spray nozzle or a spinning cone or disc atomizer. In the form of ultrafine solids, liquid or gas, a supplemental fuel may be introduced with the sewage sludge. Supplemental fuel may also be introduced into the incinerator by conventional means. Addition of tire chips in the feed provides in a higher incineration zone temperature and significantly reduces dioxin compounds present in the incineration zone off gas. Also, to reduce the scaling and fouling of the boiler tubes and incinerator, to increase the density and pumpability of the sewage sludge, and to eliminate metal salt deposits from the incinerator, the boiler feedwater and the sewage sludge are each contacted with an electromagnetic field device prior to heating.

Abstract: Low energy demand structure with side walls, roof, and foundation is disclosed wherein the side walls have inner and outer structures, the outer structure of frame construction with very heavy insulation substantially filling the outer structure. The inner surface of the outer wall structure is provided with a panel cover to hold the insulation in place and over the panel a moisture impermeable seal is placed. The inner wall structure is of vertical frame construction and provides circulating air passages and a finish interior surface. The ceiling is of similar structure with the circulating air passages of the ceiling and walls in communication with each other. The upper portion of the structure rests on foundation walls which extend at least 3-4' below the frost line and which are faced with rigid foam insulation also extending 3-4' below the frost line.

Abstract: The present invention provides an incinerator and fume separator device and a method for burning such materials as refuse, tire chips and sewage sludge or combinations thereof as well as other combustible materials to generate steam to supply steam heat and/or electricity to towns, villages or individual establishments. One of the key features of the system is the use of a horizontal conduit, wherein gases are initially cooled by a water-cooled conduit, part of the particulate material being removed within this tubing by use of baffles and fly ash settling chambers.
