Latest Patents

One of his latest patents is a heating system for liquids. This heater features an enhanced-surface area heat transfer vessel situated co-axially in a hot flue gas plenum. The plenum is formed by a dual-wall heating jacket. Liquid flowing through the jacket is heated co-currently by the flue gas before being conducted to the top of the vessel for countercurrent heat exchange. The hot flue gas flowing through the plenum is directed circumferentially by spaced and perforated ring plates placed across the plenum annulus. The aluminum construction of the vessel and jacket, along with protective coatings, contributes to a lightweight heater suitable for floor or wall mounting. This heater can be conveniently implemented in a hydronic heating system, a potable hot water system, or a combination of both.

Another notable patent is a high viscous fluid heat exchanger. This device allows for efficient transfer of sensible heat between a highly viscous fluid and a secondary fluid. The exchanger has an annular passage formed between an inner cylinder and an outer cylinder. The highly viscous fluid passes through the annular passage while the secondary fluid flows both inside the inner cylinder and outside of the outer cylinder, making both cylinders effective heat transfer surfaces. A scraper mechanism rotates within the annular passage, scraping both heat transfer surfaces. This mechanism is driven by the pressure exerted by the fluid to be cooled, serving to continually clean the surfaces and enhance heat transfer efficiency.
