Title: Glenn N Levasseur: Innovator in Steam Plant Efficiency
Introduction
Glenn N Levasseur is a notable inventor based in Colchester, CT (US). He holds 3 patents that contribute significantly to the field of steam plant technology. His innovative approaches aim to enhance efficiency and reduce operational challenges in steam plant equipment.
Latest Patents
One of his latest patents is the Steam Seal Air Removal System. This invention is designed to improve steam plant efficiency by reducing the oxygen concentration in condensate that is returned to steam generators. The system simplifies the arrangement and maintenance of steam plant equipment. It incorporates dry running shaft seals at both high and low pressure turbine shaft glands. The turbine shaft glands are connected to a vacuum header, which is managed by vacuum pumps. Additionally, air from the condenser is also directed to the common vacuum header. The system features non-rotating air seals on the turbine, such as valve stem seals, which accommodate only linear movement. These seals can utilize metallic bellows or conventional packings to prevent air leakage into the steam path or steam leakage into the surrounding environment. The bellows seals may also include stem glands that are exhausted to the turbine exhaust trunk, minimizing internal pressure and preventing catastrophic failures that could occur if the bellows were pressurized with high-pressure steam.
