Latest Patents

One of his latest patents is a "System for recovering drain." This innovative system recovers two or more flows or drains of different temperatures, which is applied to a generating plant equipped with feed-water heaters. The system efficiently manages the recovery of drain into a condensation system downstream from a condenser through a drain tank using a drain pump. It features a high-temperature recovered drain inlet positioned lower and a low-temperature drain inlet above it, allowing for effective degassing of drain with high dissolved oxygen content.

Another significant patent is the "Apparatus for deaerating condensate in a condenser." This apparatus is employed in steam turbine plants and includes an open conduit that allows condensate to flow into a covered conduit. The design ensures that the condensate is heated in the open conduit, leading to more effective and quicker deaeration, which shortens the startup time of the plant.
