Latest Patents

Ehrsam's latest patents include a method for operating a solar thermal power system with an economizer recirculation line. This innovative system features a solar receiver and a thermal energy storage arrangement that circulates thermal energy storage fluid to store thermal energy. The design incorporates a multistage steam turbine that operates on variable pressure steam generated by a steam generator arrangement, utilizing the thermal energy storage fluid. The system is equipped with an economizer section, an evaporator section, and a superheater section, all configured to utilize the heat from the hot thermal energy storage fluid to generate and supply variable pressure steam to the turbine. Additionally, the system includes a recirculation line around the economizer section to enhance the pressure range of the variable pressure steam.

Another significant patent by Ehrsam is a solar thermal power system that includes a solar receiver steam generator, a thermal energy storage arrangement, and a multistage steam turbine for driving an electrical generator. This system operates in two modes: the first mode generates steam through the solar receiver steam generator, supplying both the thermal energy storage arrangement and the high-pressure turbine inlet of the multistage steam turbine. In the second mode, steam is generated by recovering stored thermal energy from the thermal energy storage fluid for injection into the turbine downstream of the high-pressure turbine inlet.
