摘要:
A steam generation system comprises a main steam generator and a back-up steam generator (20) which are both in fluid communication with a super heater (3) for superheating the generated steam. The superheater comprises a main heat source (6) for heating up a flow of heating gas. A back-up evaporator (2) is provided as a back-up steam generator for evaporating supplied water into steam. The back-up evaporator is connected in parallel to the main steam generator. An auxiliary heat source is provided for heating up the back-up evaporator. By controlling the auxiliary heat source (9), it is possible to supply more or less heat energy to the back-up evaporator to compensate for fluctuations in steam production of the main steam generator. The back-up evaporator is positioned away from the flow of heating gasses departing from the main heat source.

Systems and methods for selectively producing steam from solar collectors and heaters, for processes including enhanced oil recovery. A system in accordance with a particular embodiment includes a water source, a solar collector that includes a collector inlet, a collector outlet, and a plurality of solar concentrators positioned to heat water passing from the collector inlet to the collector outlet, a fuel-fired heater, a steam outlet connected to an oil field injection well, and a water flow network coupled among the water source, the solar collector, the heater, and the steam outlet. The system can further include a controller operatively coupled to the water flow network and programmed with instructions that, when executed, direct at least one portion of the flow through the solar collector and the fuel-fired heater in a first sequence, and direct the at least one portion or a different portion of the flow through the solar collector and the fuel-fired heater in a second sequence different than the first sequence.

摘要:
The invention relates to a method and a device for recovering heat from an internal combustion engine, in particular of a motor vehicle, and for converting the recovered heat into mechanical energy by means of a rankine cycle-type expansion machine. In the process, a heat storage fluid conducted in a primary circuit by means of a primary pump is heated by means of a heat exchanger using the exhaust heat of the internal combustion engine, transferred into a heat accumulator, and recirculated to the first heat exchanger, and the heat storage fluid is conducted in a secondary circuit, wherein the heat storage fluid is removed from the heat accumulator in the vapor state and supplied to the expansion machine, condensed downstream of the expansion machine by means of a condenser, and recirculated into the heat accumulator by means of a secondary pump. According to the invention, the primary circuit of the heat storage fluid is connected to the secondary circuit solely via the heat accumulator and otherwise separated from the secondary circuit. The heat storage fluid is preferably kept largely in the liquid state in the heat accumulator so that a predominant fraction of the heat stored in the heat accumulator is stored in the heat storage fluid present in the heat accumulator in the liquid state.
