Title: Harold M Keener: Innovator in Fluidized Bed Combustion and Material Feeding Technologies
Introduction
Harold M Keener is a notable inventor based in Ashland, OH (US), recognized for his contributions to the fields of material feeding and combustion technologies. With a total of 4 patents, Keener has developed innovative solutions that enhance efficiency and effectiveness in various industrial processes.
Latest Patents
One of his latest patents is a "Particulate material feeder utilizing vibration and aeration." This invention describes an apparatus and method for feeding particulate material from a hopper into a process stream at a controlled flow rate. The design features a rotating wheel with spaced apart pockets that vibrate to densify the particulate material. A stator contacts and covers a portion of the upper surface of the wheel, facilitating the discharge of particulate into the process stream. The wheel's rotation is controlled to manage the flow rate, while a conveying gas supply projects a jet of gas into the pockets to remove and convey the material. Additionally, an aerating gas supply directs an upward flow of gas to fluidize the particulate material.
Another significant patent is a "Method for producing a clean heated fluid." This invention pertains to combusting dirty and/or difficult-to-burn fuel in a fluidized bed combustor. The system employs a non-intrusive counterflow cooling mechanism to control combustion temperatures and produce clean, hot gas. The combustor operates with various features, including low in-bed fuel injection and the use of finely divided fuel, enhancing its versatility and efficiency.
