摘要:
The invention relates to a method for operating a gas-and-steam combined cycle power station (10) in which exhaust gas is produced by a gas turbine (12) and is supplied to a steam generator (20), wherein hot steam is produced using the exhaust gas supplied to said steam generator (20) and by means of said steam generator (20), and this steam serves to drive at least one generator (30) using at least one turbine device (22) in order to provide electrical current. The exhaust gas supplied to the steam generator (20) is conducted away from said steam generator (20), and at least one portion of the heat contained in the exhaust gas, downstream of the steam generator (20), is used to initiate an endothermic chemical reaction.

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.

System and method for accumulating steam in tanks for solar use made up of two sets of Ruths tanks (1, 2), called base set and overheat set, identical to one another and each having a saturated steam inlet (3), steam injectors (10) installed inside the tank (1, 2), a steam outlet (4, 4') with a valve (13) and drainage means (11). A heat exchanger (6) is installed between the two sets of tanks (1, 2). The method of storage consists of a tank loading stage and a tank discharging stage, the latter comprising two discharging phases, the first one from a maximum to an intermediate pressure and the second one from an intermediate to a low pressure.

The present invention relates to a system (100) for storing heat energy comprising a fluid cycle (101) through which working fluid is streamable, and a heat storage device (110) configured for storing heat energy, wherein the heat storage device (110) comprises a first fluid opening (111) and a second fluid opening (112) each being coupled to the fluid cycle (101) such that the working fluid is streamable between the first fluid opening (111) and the second fluid opening (112) through heat storage device (110) transferring thermal energy between the heat storage device (110) and the working fluid. The system (100) further comprise a mass regulation device (120) which is coupled to the fluid cycle (101), wherein the mass regulation device (120) is configured for adjusting the mass of the working fluid in the fluid cycle (101) on the basis of the pressure and/or the temperature of the working fluid. A mass regulation device (120) is coupled to the fluid cycle (101), wherein the mass regulation device (120) is configured for adjusting the mass of the working fluid in the fluid cycle (101) on the basis of the pressure and/or the temperature of the working fluid, and wherein the mass regulation device (120) comprises a pressure control valve (124) for adjusting the pressure difference between fluid cycle (101) and the surrounding system, thereby adjusting the absolute pressure in the fluid cycle and thereby exhausting and/or feeding mass of working fluid out of or into the fluid cycle (101).
