Title: Innovations of Richard A Griffith
Introduction
Richard A Griffith is an accomplished inventor based in Morgantown, WV (US). He has made significant contributions to the field of combustion technology and materials handling through his innovative patents. With a total of two patents to his name, Griffith's work focuses on enhancing the efficiency and reliability of combustion devices and valves used in abrasive materials.
Latest Patents
Griffith's latest patents include the "Periodic equivalence ratio modulation method and apparatus" and the "Sliding-gate valve for use with abrasive materials." The periodic equivalence ratio modulation (PERM) method significantly reduces and/or eliminates unstable conditions within a combustion chamber. This method involves modulating the equivalence ratio for the combustion device, allowing it to operate outside of identified unstable oscillation regions. The modulation is achieved through active control involving periodic, low-frequency fuel modulation, ensuring that the desired time-average equivalence ratio remains unaffected.
The sliding-gate valve invention is designed for use with abrasive solids. It features upper and lower transversely slidable gates contained in separate chambers. The upper gate controls the flow of solids, while the lower gate provides a pressure-sealing function. This design ensures long, reliable operating lifetimes in solids-handling service, as the sealing surface of the lower gate is shielded from solids during operation.
