摘要:
Solar energy generates steam in a “once-through” configuration without recirculation, with closely managed steam quality, to produce wet steam from high-contaminant feed water without scaling or fouling. Feed water is pressurized, preheated, and evaporated in a series of pipes exposed to concentrated solar energy to produce a water-steam mixture for direct distribution to an industrial process such as enhanced oil recovery or desalination. Water flow rates are managed based on measurements of solar energy and steam production to manage variations in the solar energy. Steam generator piping system uses continuous receiver pipe that is illuminated by segmented parabolic mirrors enabled to track the sun. Provisions for steam generator piping recurring maintenance are provided. Thermal energy from hot condensate and/or from low quality steam is recaptured and warms inlet water.

Solar energy is collected and used for various industrial processes, such as oilfield applications, e.g. generating steam that is injected downhole, enabling enhanced oil recovery. Solar energy is indirectly collected using a heal transfer fluid in a solar collector, delivering heat to a heat exchanger that in turn delivers heal into oilfield feedwater, producing hotter water or steam. Solar energy is directly collected by directly generating steam with solar collectors, and then injecting the steam downhole. Solar energy is collected to preheat water that is then fed into fuel-fired steam generators that in turn produce steam for downhole injection. Solar energy is collected to produce electricity via a Rankine cycle turbine generator, and rejected heat warms feedwater for fuel-fired steam generators. Solar energy is collected (directly or indirectly) to deliver heat to a heater-treater, with optional fuel-fired additional heat generation.

A trough type solar thermal collector which uses a curved mirror to make a heat tube which is arranged in the front of the curved mirror collect sunlight and to heat a fluid which flows through the inside of the heat tube, the trough type solar thermal collector configured to be able to avoid damage to the curved mirror due to vortex-induced vibration, is provided. The trough type solar thermal collection apparatus of the present invention is provided with, at an outer edge of the curved mirror in the direction of change of curvature of the curved shape of the curved mirror, vortex control means for controlling the flow of vortices which forms at the outer edge, whereby it is possible to avoid damage to the curved mirror such as occurs due to vortex-induced vibration at the time when higher windspeed resistance specifications are sought from the apparatus.

A solar collector system is provided including a bearing assembly comprising a plurality of wheels or rollers for rollingly engaging a large-diameter support element. Rotation of the large-diameter support element supports tracking of the position of the sun relative to the solar collector system. The bearing assembly may be pre-assembled to the large-diameter support element before the solar collector system leaves the factory, thereby facilitating assembly of the solar collector system in the field, even under adverse conditions.

A reflector element carrier structure is disclosed for use in a solar energy reflector system. The structure comprises a reflector element (11), a corrugated platform (12) which carries the reflector element and a skeletal frame structure (13) which supports the platform. The frame structure comprises hoop-like end members (14) that are supported by rollers (18) and the rollers accommodate turning of the carrier structure about an axis of rotation that lies substantially coincident with a longitudinal axis of the reflector element (11). The combination of the corrugated platform (12), the frame structure (13) and the hoop-like end members (14) of the frame structure provide the carrier structure with a torsional stability that permits the application of turning drive from one end of the structure.
