A power generation system using a combined solar-assisted fuel reformer and oxy-combustion membrane reactor is proposed. The system uses solar heating to activate the endothermic fuel steam reforming reaction. The produced gas is separated into streams of H.sub.2 and CO for separate oxy-combustion reactions. The O.sub.2 used in the oxy-combustion reactions is produced by permeating O.sub.2 through ion transport membranes in contact with solar-heated air.

TURBINE WITH SOLAR COLLECTOR OR TURBOCHARGER, which is designed to originate innovative turbine kinetic energy through solar irradiation, irradiated by heliostats, parabolic or possibly to function with other types of fuel when not no solar radiation. With a heat exchanger through which passes the residual thermal energy is achieved in a higher efficiency than conventional turbines. In this set of turbine exchanged, collector and collector, its components are located so that the drop of the thermal fluid is the minimum possible. The team has been solar collector incorporated a radial type where the sunlight is irradiated, which in the collector, the heated fluid flowing through it which comes from the compressor, through the heat exchanger, and that the empty on the blades of the turbine motor generating a kinetic energy of a mechanical element that needs a turning force or power generators. This system can be developed to produce electric power from 1 kW to 15 kW in parable and even over twenty megawatts radiated tower heliostats. At low power is designed for can use the sensor and the sensor turbine or a turbocharger. No water uses er, no pollution and low installation costs, very significantly given the simplicity and innovation of its components.

Disclosed are systems and methods for pump control of a closed thermodynamic cycle system, such as a Brayton cycle. Operational parameters such as working fluid temperature, thermal fluid temperature, stream pressure, and power generation may be the basis for controlling a thermal fluid pump rate.

A solar receiver includes a hollow body, which has a longitudinal axis (8.4), a wall (8) surrounding the longitudinal axis (8.4), an opening (9) disposed in the wall (8) for the entry of heat rays, and an end region opposite the opening (9). The wall (8) includes an outer wall (8.1), an inner wall (8.2), and a partition wall (8.3) disposed therebetween. The outer wall (8.1) and the partition wall (8.3) enclose an outer annular space (8.1.1). The inner wall (8.2) and the partition wall (8.3) enclose an inner annular space (8.2.1). The outer annular space (8.1.1) has, in the end region, an inlet (12) for a free-flowing medium. The two annular spaces (8.1.1, 8.2.1) are conductively connected to one another in the region of the opening (9), and the inner annular space (8.2.1) has an outlet (11) for a free-flowing medium in the end region.
