Abstract: A boiler system (101) comprises a boiler (2) for combusting a fuel in the presence of a gas containing oxygen gas, and a gas cleaning system (106). The boiler system (101) comprises a compression device being operative for pressurizing at least a portion of the carbon dioxide rich flue gas from which at least a portion of the contaminant content has been removed, and a carbon dioxide supply duct (142; 143; 145) being operative for forwarding at least a portion of the pressurized carbon dioxide rich flue gas to at least one gas cleaning device (108; 110; 111) for being utilized as a utility gas therein.

Abstract: An exhaust system associated with a power source is disclosed. The exhaust system may have an exhaust stack extending from the power source to an exterior of the exhaust system and a moisture collection device disposed within the exhaust stack to collect moisture from the exhaust stack. The exhaust system may also have a moisture entrainment device associated with the moisture collection device to facilitate entrainment of the collected moisture into an exhaust flow of the power source.

Abstract: An air filter arrangement for an agricultural combine located on a panel at a side wall of the agricultural combine. The air filter arrangement includes a rotary filter mounted for rotation at a first aperture, a scoop enclosing the rotary filter and blocking substantially all air flow to the rotary filter except at a scoop inlet disposed along an upper edge of the scoop above the rotary filter, and at least one stationary filter disposed to filter air passing through a second aperture in the panel, the stationary filter being located between an upper portion of the rotary filter and the scoop inlet.

Abstract: In a moisture separator, a manifold that communicates with a steam inlet is disposed in a shell; a plurality of blowout outlets for steam is provided on a side of the manifold; a first support plate and a lower support frame are fixed to a lower part in the shell to compart a steam drift space and a drain path; a moisture separating element is provided corresponding to the manifold; steam from which moisture is removed by the moisture separating element is heated by the group of the heating tubes to flow as high-temperature reheat steam to the steam outlet; the moisture is led from the drain opening through the drain path to the drain outlet; and a blocking plate that blocks a part of the drain opening is provided.

Abstract: An air routing device for a motor vehicle air conditioning and/or heating system, comprising an air routing housing on which a blower is arranged, wherein the air routing device is formed separately from the air routing housing and can be pushed into the air routing housing through alternate housing orifices located opposite one another.

Abstract: The present invention relates to a process for recovering subliming substances, which deposit in the form of crystals, from a subliming substance-containing gas by combining a cooling operation for lowering the temperature of collecting tubes for the deposition of crystals below the temperature at which the crystals deposit with a heating operation for heightening the temperature of the collecting tubes above the temperature at which the crystals deposit. A subliming substance is continuously recovered in the form of crystals at a high ratio without suffering the recovered crystals from developing a color.

Abstract: A method and apparatus for continuously removing siloxanes and H2O from a waste gas stream containing H2O and siloxanes includes cooling the waste gas stream in a primary heat exchanger to a temperature of greater than 2° F. to condense a portion of the H2O from the waste gas stream, chilling the waste gas stream in a first gas-refrigerant heat exchanger to a temperature of about −20° F. to condense the siloxanes and freeze the H2O and then directing the cooled waste gas stream from the primary heat exchanger to a second gas-refrigerant heat exchanger while the first gas-refrigerant heat exchanger is defrosted to remove frozen H2O and siloxanes.

Abstract: Phthalic acid anhydride is recovered from a gas stream containing phthalic acid anhydride vapors by passing the gas stream upwardly through a vertical tube so that the gases expand at the orifice at the upper end of the tube and mix with granules entrained above the tube by fluidizing gas of a fluidized bed of phthalic acid anhydride granules around the tube. The tube, kept free from phthalic acid anhydride granules and the fluidized bed, is indirectly cooled.

Abstract: Disclosed is an apparatus for effectively treating waste gases which are discharged during a processing of manufacturing semiconductors. The apparatus for treating waste gases according to an embodiment of the present invention comprises a waste gases heating chamber, a waste gases collecting chamber, a waste gases collecting chamber cover, a scraping device for the waste gases collecting chamber cover, a scraping device for the waste gases collecting chamber, and a driving source for driving the scraping device for the waste gases collecting chamber cover, and the scraping device for the waste gases collecting chamber. The apparatus for treating waste gases further includes a cooling tube which is disposed on an outer surface of the waste gases collecting chamber, for cooling waste gases.
