摘要： A control method for optimizing a solar-to-power efficiency of a solar-aided coal-fired power system under off-design working conditions is provided. Through reading the relevant information of the solar collecting system, the coal-fired power generation system, the environmental conditions, and the working conditions of the solar-aided coal-fired power system, the water flow rate range able to be heated by the solar collecting unit and the solar-coal feedwater flow distribution ratio range of the solar-aided coal-fired power system are determined; through establishing the relationship between the solar-to-power efficiency and the solar-coal feedwater flow distribution ratio of the solar-aided coal-fired power system under the off-design working conditions, the solar-coal feedwater flow distribution ratio is regulated, so that a flow rate of water entering the solar collecting system to be heated is controlled, thereby maximizing the solar-to-power efficiency and improving the economy of the solar-aided coal-fired power system under the off-design working conditions. The present invention provides clear guidance to optimize the solar-aided coal-fired power system under the off-design working conditions, enable solar energy to fully play its role in the solar-aided coal-fired power system, improve the utilization rate of solar energy, facilitate the consumption of the renewable energy, and greatly increase the economy of the solar-aided coal-fired power system.

摘要： Technologies are disclosed herein for a thin heat exchanger through which coolant may be pumped. The heat exchanger may include an envelope and a heat conduction layer provided over the envelope. The envelope may include one or more channels formed therein. The channels formed between the envelope and the conduction layer may extend the length of the heat exchange layer and be configured to carry coolant therethrough. The heat exchange layer may include an inlet manifold on a first end and an outlet manifold on another end opposing the first end. The inlet manifold may allow the flow of coolant into the heat exchange layer and the outlet manifold may allow the removal of the coolant from the heat exchange layer. Coolant flow may be controlled by a suction pump operating under computer control based at least in part on sensor data.

摘要： A concentrator and a solar light router for converting light energy into electrical, photochemical and thermal energy, among other possible forms of usable energy, comprising a fixed body (1) and a movable part (2), wherein the fixed body (1) has an upper side with a converging lens (4) through which the sun rays (R1) enter, and a lower side where a mirror (5) is arranged. The mobile part 2 has a support arm 7 having a lower leg 8 coupled to a movement unit 10, and an upper leg 9 extending above the converging lens 4, in which is displaceable mounted a module (11) receptor/router of convergent solar rays (R4) that emerges from the fixed body (1). The support (7) is connected to angular displacement means housed in the movement unit (10) so that the angle traveled by its arm (9) encompasses a virtual surface (17), defined between the converging lens (4) and the module (11), where a focal point (19) incise of the convergent rays (R4), that travels according to the curvilinear paths (18n) in accordance with the displacement of the sunlight captured by the converging lens (4). The module (11) presents a lower face (13) through which the converging solar rays (R4) enters, and an upper face (14) from which concentrated solar rays (R5) are emitted which are directed, for example, towards a solar energy converter receiver (20) arranged in a tower (T) spaced from the device. The module (11) is connected to translation means along the upper section (9) of the support (7) and to rotating means with respect to its axis (E1) transverse to the defined plane by the converging lens (4) and includes means detecting the positions of the focal point (19), which together with the angular arm displacement means (7) and the translational and rotational means of the module (11) are connected to a module position control and control unit (11) to maintain it facing the focal point (19) and facing the receiver/solar energy converter (20) of the tower (T). In an alternate realization, the module (11) may act as a solar energy receiver/converter, for which it may include solar cells, a thermoelectric motor, or other solar energy converters.

摘要： A control method for optimizing generated power of a solar-aided coal-fired power system under off-design working conditions sets maximizing generated power without changing main steam flow rate as a control goal. A solar-coal feedwater flow distribution ratio is adjusted to adjust water flow rate heated by a solar heat collection system, so as to achieve the control goal. Control steps include reading relevant information; calculating the water flow rate range heated by the solar heat collection system, and an applicable solar-coal feedwater flow distribution ratio range; establishing a correspondence between the generated power and the solar-coal feedwater flow distribution ratio within this range; selecting a solar-coal feedwater flow distribution ratio corresponding to the maximum generated power; and adjusting the water flow rate entering the solar heat collection system to an optimized value. The present invention can flexibly control the solar-coal coupling and improve the economy.
