Latest Patents
One of Stendahl's latest patents is a gas-to-gas heat exchanger. This invention comprises a chamber through which at least one first tube passes for the passage of a first hot gaseous medium, alongside at least one second tube for a cooler gaseous medium. The tubes are arranged in a spaced-apart manner, creating a fluidized bed of particulate material, such as sand, in the chamber. This fluidized bed serves as a heat transfer medium, allowing for efficient heat exchange, particularly suitable for preheating air using hot, dust-laden gas. The design may include multiple chambers stacked vertically for enhanced performance.
Another significant patent is for an apparatus designed for cooling dust-containing gas. This apparatus facilitates the cooling and distribution of gas within a bed containing a powdered or granular material. It features a structure that blows gas under pressure into the powdered material, creating a fluidized bed. The gas distribution is achieved through straight, horizontally positioned tubes located at the lower portion of the bed, which may also draw water through the powdered material.
