Title: Innovations by Wilbur E. Stephens
Introduction
Wilbur E. Stephens is a notable inventor based in Redwood City, CA, who has made significant contributions to the field of furnace technology. With a total of three patents to his name, he has developed innovative solutions that enhance the efficiency and effectiveness of heating processes in industrial applications.
Latest Patents
One of his latest patents is the High Velocity Billet Heater. This invention involves transporting a billet through an improved furnace using conventional means. The billet is heated by an external burner unit where fuel and air are combusted together and injected at high velocity into a semi-cylindrical chamber of the furnace. This design creates a hot vortex of gases that circulates around the billet, allowing for precise temperature control. A thermocouple is strategically placed near the billet surface to monitor the temperature of the circulating gas, ensuring the billet is heated to the desired temperature and maintained effectively.
Another significant patent is the Recycle Burner System. This invention features a reverberatory furnace equipped with an external passage for recycling hot exhaust gases back to the main burner port. It includes mechanisms for introducing additional air or oxygen into the recycling passage. The main burner supplies fuel along with up to 50 percent of the air or oxygen needed for total combustion. This innovative design preheats the additional air or oxygen using exhaust gases, leading to complete combustion and reduced fuel costs.
