Title: Lowell D. Fraley: Innovator in Combustion Technology

Introduction

Lowell D. Fraley is a notable inventor based in Sugarland, TX (US), recognized for his contributions to combustion technology. He holds a total of 4 patents, showcasing his innovative approach to solving complex engineering challenges.

Latest Patents

Fraley's latest patents include a method for reducing mode circulating fluid bed combustion. This method allows for the combustion of sulfur-containing fuel in a circulating fluid bed combustion system, where the fuel is burned in a primary combustion zone under reducing conditions. Sulfur is captured as alkaline sulfide, and the reducing gas formed is oxidized to combustion gas, which is then separated from solids containing alkaline sulfide. The separated solids are subsequently oxidized and recycled to the primary combustion zone. Another significant patent is for a fired process heater, where combustion gas passes upwardly through the radiant section of a fired process heater with vertical tubes. This design ensures that the gas is in predominantly back-mixed flow condition in the lower portion and predominantly plug-flow condition in the upper portion of the radiant section.
