Abstract: The present invention provides a method for reducing slag build-up in cyclone furnaces comprising introducing into a cyclone furnace at least one of a slag viscosity modifier and a combustion adjuvant, wherein a substantial portion thereof is conveyed to the walls of the furnace by addition through the secondary air stream. Preferably the additives are formed as particles of sufficient size and density that they are driven directly to the walls of the furnace. This method alleviates slag build-up caused by the presence of uncombusted coal particles at the walls and increases the temperature environment at the walls.

Abstract: Gravity flow in generally vertical stack lines in buildings and dwellings is improved by the application at the top of the drain of a concentrate of a water-soluble vinyl addition polymer, said concentrate being a water-in-oil emulsion which has a water-soluble vinyl addition polymer concentration between 20 and 50% by weight based on the total emulsion which exhibits unusual stability properties. The invention also applies to lubrication of garbage prior to its entry into garbage disposals.

Abstract: A method of breaking oil-in-water emulsions involving treating such oil-in-water emulsions with a polycationic water-soluble condensation copolymer. Treatment with the copolymer transforms the emulsified oil particles into flocs which may be directly removed or which may be removed after the addition of one or more flocculants.
