摘要： Improved apparatus and methods for the treatment of boiler flue gas with sulfur trioxide conditioning agent include the beneficial use of catalytic converters that can be located immediately adjacent the injection site for their sulfur trioxide output, that can be individually sized and manufactured for variable required conditioning agent outputs, that can be individually controlled and can provide substantially improved conversion efficiency and that can provide an efficient, flexible, effective and relatively inexpensive multi-boiler flue conditioning system.

摘要： Effluent gas streams from power plants, or other sources, containing entrained particulate matter are conditioned by injecting a conditioning gas such as sulfur trioxide into the flowing gas stream. The conditioning gas is deposited upon the surface of the particulate and reduces its electrical resistivity, improving the performance of electrostatic precipitators through which the flowing gas is passed to precipitate the particulate. At the point of injection, an electrostatic potential is established between the particulate in the flowing gas stream and the conditioning gas molecules, so that the conditioning gas is attracted to the particulate. Interaction of the conditioning gas with the particulate is stronger and more rapid than in the absence of the electrostatic potential at the point of injection.

摘要： Disclosed is an improved process for the production of a sulfur trioxide conditioning gas, which consists in compensating the faulty "ambient gas temperature" in a simple and effective manner, such that all of the subsequent functions can take place at the established optimum temperature and can no longer be adversely affected by fluctuations in the ambient air temperature.

摘要： The present invention relates to operation of a rotary kiln plant utilizing electrostatic precipitators. Specifically, this invention is directed to a method for conditioning exhaust gases from a burning process in a rotary kiln in which mineral materials are treated by burning a fuel. The method comprises adding a water soluble alkali-metal compound to a solid fuel, at least part of which is a solid pulverized fuel, and then firing the fuel in the kiln plant, whereby the resistivity of the exhaust gases is less than about 10.sup.10 ohm cm.

摘要： The collection characteristics of particles entrained in a particle-laden gas for separation by the commonly used methods for removing particles from a gas stream are improved by injecting into the gas stream a conditioning agent comprising diammonium phosphate and urea. The conditioning agent can be added to the gas stream either at low temperatures or at high temperatures, in both cases giving rise to significant improvements in emission characteristics. The additive of the present invention has a very significant advantage over prior art additives of substantially equal emission improvement characteristics of greatly reducing or substantially eliminating buildup of hard-to-remove deposits.
