  • Patent number: 9303899
    Abstract: A solar energy-powered heating and cooling system for buildings, including solar energy tiles attached to a roof or an outside surface of walls of a building, an energy collector used to concentrate energy collected by the solar energy tiles, an energy converter activating solar energy into another form of energy, supply pipes hidden inside cavity floor and/or hollow walls and containing a flow medium, and an intelligent control unit. The solar energy collected by the solar energy tiles is brought to the energy collector and then converted via the energy converter. The energy is instilled into the flow medium that is subsequently transferred to the cavity floor and/or hollow walls via the supply pipes so as to either heat up or cool down the building. The process is controlled by the intelligent control unit.

  • Patent number: 9242221
    Abstract: A plant for chemical or physical treatment of granular solids includes a fluidized-bed reactor, a solids supply conduit and a central gas supply tube. A cooling tube is disposed relative to the gas supply tube so as to form an annular cooling duct, which is configured to cool the gas supply tube and the process gas and is connected with a coolant source configured to supply a coolant with a temperature of below about 400° C. Outlet openings are disposed in the cooling tube. The fluidized-bed reactor is a Venturi reactor in which the cooling tube opens into a flared portion with the outlet openings connecting the annular cooling duct with the reactor interior. The cooling tube adjoins the gas supply tube and extends substantially parallel to the flared portion of the reactor.

  • Patent number: 9243843
    Abstract: The present disclosure concerns a drying or heating apparatus that is capable of independently controlling the temperature of the product being heated (e.g., to achieve a desired temperature profile) and the wavelength of the radiation (e.g., to maximize the heat transfer rate). To such ends, a drying apparatus can be provided with one or more heat sources that are movable relative to the product being heated in order to increase or decrease the gap or spacing between the heat source and the product. By adjusting the gap between the product and the heat source, it is possible to control the source temperature in such a manner that produces the desired product temperature and wavelength of radiation.

  • Patent number: 9220276
    Abstract: An improved spiral oven and method for its use includes the step of using a forward/reversing fan to produce a first airflow and a second inverted airflow in the cooking chamber. The proportion of time each airflow occurs may be unbalanced within an oven residence time or cook cycle, and either airflow may begin the cycle. The first airflow creates a flow across the cook belt predominantly at the top and bottom tiers, whereas the second airflow creates this flow predominantly in the middle tiers. A braking resistor allows the fan to quickly changeover between full-forward and full-reverse directions. Because of the reversing airflow pattern, the product cooks more evenly across the cook belt.

  • Patent number: 9212828
    Abstract: An Epicatalytic Thermal Diode (ETD) includes one or more ETD cells. Each cell comprises first and second surfaces with a cavity between them, which contains a gas that is epicatalytically active with respect to the pair of surfaces. The surfaces chemically interact with the gas such that the gas dissociates at a faster rate proximate to the first surface than it does proximate to the second surface. Thus, a steady-state temperature differential between the first surface and the second surface is created and maintained. In various applications, multiple ETD cells are connected in series and/or parallel.

  • Patent number: 9212451
    Abstract: An electrical resistance heater assembly includes a heater housing forming a channel having a longitudinal axis for a fluid such as air to pass through and a heater support plate forming first and second levels in the heater housing. A first mica board assembly supporting a ribbon heater is mounted to the heater support plate at the first level and a second mica board assembly supporting a ribbon heater is mounted to the heater support plate at the second level. The first level is positioned adjacent an inlet of the heater housing and the second level is positioned adjacent an outlet of the heater housing. The first level and a side of the heater housing form a passageway for air to enter the heater housing and be directed to the ribbons of the second level, thereby allowing air to bypass the heater ribbons of the first level.

  • Patent number: 9194579
    Abstract: A radiant wall burner apparatus. The apparatus includes an inlet and primary fuel tip for introduction of fuel gas and air mixing in a mixing chamber. The fuel and air mixture are subject to a substantially uniform flow area from the point of discharge from a downstream portion of the mixing chamber up to the exit gap of the burner tip. The fuel gas and combustion air mixture terminate through the burner tip at a substantially uniform velocity. The radiant wall burner apparatus and burner tip allow for the substantially uniform velocity of the fuel gas and air mixture, reducing the potential for flashback of the burner tip.
