Title: Innovations of Markus A. Eggenberger
Introduction
Markus A. Eggenberger is a notable inventor based in Schenectady, NY (US). He has made significant contributions to the field of turbine technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and safety of steam turbines, which are critical components in power generation.
Latest Patents
One of his latest patents is a turbine control system for sliding or constant pressure boilers. This automatic control system enables comprehensive operation of a reheat steam turbine with sliding or constant pressure boilers. The control system includes an HP control valve for regulating steam flow to the high-pressure turbine according to load and speed demands. It also features an intercept valve for regulating steam flow to the low-pressure turbine and for reheater pressure control. Additionally, a bypass flow system is included for bypassing excess boiler steam during periods of low loading. This system consists of a high-pressure bypass sub-system and a low-pressure bypass sub-system, each equipped with a flow control valve and provisions for desuperheating the steam. A signal indicative of actual load demand (ALD) is produced, which is proportional to the product of boiler pressure and main control valve flow demand. From the ALD signal, reference functions are generated to effect control of the bypass valves. The intercept valve is controlled directly by the ALD signal with a regulation factor inversely proportional to the minimum allowable reheat pressure. Coordinated valve control is achieved during all principal phases of turbine operation.
Another significant invention is a moisture detector for steam lines. In a steam turbine, the presence of water slugs can adversely affect certain turbine parts, particularly at the low-pressure end where excess moisture is more likely to occur. This invention provides a monitoring device for a steam conduit that detects the presence of water slugs or wet steam and indicates a reverse direction of flow in the steam conduit.
