  • Patent number: 11262068
    Abstract: The present device is a fluid bed regenerative thermal oxidizer configured to minimize dead spaces within it and eliminate the need for complex valve systems, which are typically required to move treated and untreated air across fixed beds. The present device can be a fluid bed regenerative thermal oxidizer comprising a vertical stack having a combustion chamber near its interior center and desorber shelves located within the vertical stack above the combustion chamber and adsorber shelves located within the vertical stack below the combustion shelves. Ceramic spheres can be used as heat sinks that flow from the desorber shelves, around the combustion chamber and onto the adsorber shelves and then back to the desorber shelves. In this way heat from the combustion can be captured by the heat exchange material on the desorber shelves and released to preheat untreated air on the adsorber shelves.

  • Patent number: 10449478
    Abstract: A method for removal of a foulant from a carrier gas is disclosed. A solids conveyance device that spans a vessel and a solids coolant system are provided. A cold solid foulant is provided to the solid inlet of the vessel. The carrier gas containing the foulant is provided to the carrier gas inlet of the vessel. The foulant condenses or desublimates onto the recycled solid foulant, forming a foulant-depleted carrier gas and a solid foulant product. The solids conveyance device passes the solid foulant product out of the vessel. The foulant-depleted carrier gas leaves the vessel. The solid foulant product is split into a final solid foulant product and a recycled solid foulant. The recycled solid foulant is cooled through the coolant system to produce the cold solid foulant. In this manner, the foulant is removed from the carrier gas.

  • Patent number: 6470834
    Abstract: The invention relates to a method and a device for utilizing the heat of flue gases from combustion apparatus while simultaneously removing condensable elements from the flue gases and reducing the corrosivity of the flue gases. The method is applicable to all types of combustion apparatus where a combustion zone generates hot flue gases that are cooled in one or more heat exchangers that transfer the utilizable heat to a liquid or a gas. The method is also suitable for apparatus with considerable load fluctuations, where the fuel supply must be adjusted to the heat load. This is achieved by separating the flue gases from the heat exchangers by cooling the flue gases by means of a particulate material (2, 13) which absorbs the condensable substances, and by circulating the particulate material between the flue gases and heat exchangers (10) that transfer heat to the hot liquid or gas.

A metallic conveyor belt driven by a motor is placed within the container, and the material from the downstream end of the channels is laid on the conveyor belt, thus forming a travelling continuous bed. The belt therefore constitutes a regenerative heat exchanger which absorbs heat from the material during the forward run and gives it back to the air during the backward run.
