Latest Patents

Herman Nack's recent patents showcase his expertise in developing advanced filtration systems and combustion techniques. One of his latest inventions is the "Nested, Recirculating-Fiber Filter." This innovative filter employs high aspect ratio fibers that nest together to create a high voidage fiber filter bed, effectively removing particulates from moving fluid streams. The method involves a continuous cycle where fibers are removed from the filter bed, regenerated to eliminate impurities, and recycled. This process enhances the filter's efficiency by ensuring that a fresh volume of fibers is available at the top of the bed for optimal particulate capture.

Another notable patent is the system for "NO.sub.X Reduction in Multisolid Fluidized Bed Combustors." This invention significantly reduces nitrogen oxide pollutants while minimizing sulfur dioxide emissions through staged combustion processes. The lower combustion region operates under controlled conditions to reduce NO.sub.X using carbon and carbon monoxide, while the upper region ensures complete combustion by maintaining excess oxygen. This dual approach helps prevent elevated temperature excursions that could hinder sulfur capture.
