  • Publication number: 20140352169
    Abstract: A temperature-controlling tunnel is accommodated in a housing and defines at least one tunnel portion, which comprises at least one air outlet and at least one air inlet. The tunnel portion is paired with a heater assembly in which a hot primary gas can be generated by means of a burner unit. The hot primary gas can be conducted into a heat exchanger of the heater assembly, and tunnel air can be heated in the heat exchanger by means of the hot primary gas and fed back to the tunnel portion via the at least one air inlet in a circuit as a circulating air flow. A burner supply device is provided by means of which exhaust air from the tunnel portion can be fed to the burner unit of the heater assembly as a burner air flow in order to generate the primary gas.

  • Patent number: 8819957
    Abstract: A portable air heating system provides a stream of heated air. The heating system generally has an air transfer assembly for providing a flow of air through the system, a fuel burner assembly having one or more burners for providing heat by combustion, and a heat transfer housing for safely transferring the heat produced by the fuel burner assembly to the air flowing through the transfer assembly. The burner assembly has burners with inlets having generally horizontal axes that are disposed from one or more heat transfer tubes mounted in the heat transfer housing. The burner assembly and the heat transfer assembly are positioned outside the area being heated so that the exhaust gases are completely isolated from the air heated by the system, thereby virtually eliminating the likelihood of asphyxiation by the exhaust gases from the burner.

  • Patent number: 5444922
    Abstract: The invention relates to a single pass airflow apparatus for cooling and drying corrugated product having open flutes, comprising an airflow exhaust duct having a first cross-sectional area, an inlet plenum with a cross-section area greater than the airflow exhaust duct and having an exit in airflow communication with an inlet to the airflow exhaust duct. The plenum has an open faced chamber abuttingly facing the stack of corrugated product which presents the open flutes to the plenum. A fan is provided for drawing airflow through corrugated product into the plenum and from there into airflow exhaust duct from whence the drawn air is exhausted to atmosphere. The invention is directed to the structure and to the method of its use.

  • Patent number: 5309650
    Abstract: A paint baking oven utilizes air flow throughout the oven to ventilate solvents and/or resins which evaporate off during the paint baking process. Air is continuously introduced through air seals located along the paint baking oven at various points. This ventilation air is directed toward the center of the paint baking oven where it is exhausted at a rate proportional to the rate at which the ventilation air is introduced into the paint baking oven. Removing the solvent and/or resin laden air from the paint baking oven results in a more desirable final finish on the component being baked.

  • Patent number: 5037545
    Abstract: A liquid recovery system and method for precipitating dissolved solid material out of a spent liquid, and for thereafter separating the precipitated solid material from the liquid to provide a recovered liquid. The system includes a first tank for receiving spent liquid in a substantially continuous manner, a second tank for receiving a quantity of spent liquid from the first tank, a separator for separating solid material from the spent liquid in the second tank to provide a recovered liquid in the second tank, a third tank for receiving a quantity of recovered liquid from the second tank, and output means for delivering recovered liquid from the third tank in a continuous manner. The separator includes a separator tank through which spent liquid in the second tank is circulated during a circulation period to separate precipitated solid material from the spent liquid.

  • Patent number: 4845860
    Abstract: An improved method and apparatus for treating fibrous material are shown. A concurrent stream of air and fibrous material are spewed into an empty chamber large enough to allow the fibrous material to fall out of the conveying air into a collecting duct where the two components are removed in a concurrent stream having the normal conveying velocity. An evase section at the entrance of the chamber promotes the slowing of the seed cotton, allowing it to come to a state of agitation with respect to the air in the chamber before being drawn out the chamber exit where it is again accelerated with the outgoing stream of air.

  • Patent number: 4610098
    Abstract: Double-flow dehydration tunnel characterized in that it comprises, above an intermediate space (5), a collecting and channelling means (20) arranged to collect separately the current of hot air (10) coming from the recycling duct (7) containing the heater (9) and the current of less hot air (15) coming from the recycling duct not containing a heater, to divert these two substantially horizontal currents into substantially vertical currents and to channel them in the form of a multitude of laminar streams (32, 33) parallel to the vertical axial plane of the tunnel, the streams (32, 33) from one source and the other being in alternate positions and axially offset at least on one edge, in such a manner that their mixing produces an air current comprising two zones (34, 35) at different temperatures in the axial direction and substantially homogeneous in the transverse direction, the less hot zone (35) being oriented on the side where the parallel flow section (4) is located.

  • Patent number: 4530700
    Abstract: Biomass is prepared for use as a fuel or chemical feed stock either by processing biomass to provide particles or by utilizing such particles that have been independently produced, in either case at a location remote from consuming sites. At a thus situated location, particles are delivered to at least one gas producing section and to a drying section with hot producer gas utilized in the drying section in a manner to so reduce the moisture content of the particles as to render the particles a more efficient fuel or chemical feed stock.
