The forerunner of concentrating solar power is Gilbert Cohen of the United States, which has built a large-scale concentrating solar power station in Nevada, USA, and has successfully supplied 22 megawatts of electric energy to Las Vegas. Concentrating solar power generation, after wind energy and photovoltaic cells, has begun to emerge, and is expected to become an effective technical means to solve energy shortages and cope with climate warming. Basic principle: concentrating solar power uses a parabolic mirror to concentrate the light onto a heat-absorbing tube filled with synthetic oil, and then delivers the synthetic oil heated to about 400 degrees Celsius to the heat exchanger, and the heat is passed through the heating circulating water. Water is heated to generate water vapor, which drives the turbine to turn the generator to generate electricity. Concentrating solar power is different from solar cells. Solar cells use solar panels to convert solar energy directly into electricity. They can be operated on cloudy days. CSPs can only be used in sunny and sunny places. However, even in the absence of the sun, the use of molten salt to store heat can now solve the problem of all-weather power supply. The predictions of the International Energy Agency (IEA) SolarPACES, the European Solar Thermal Power Generation Association (ESTELA) and Greenpeace are more moderate, and CSP will account for 3%-3.6% of global energy supply by 2030, by 2050. It accounts for 8%-11.8%, which means that by 2050, CSP installed capacity will reach 830GW, adding 41GW per year. In the next 5-10 years, the cumulative annual growth rate will reach 17%-27%.

The
furnace and roof are made up of membrane water wall and hung on the
steel structure by upper hanging suspender of water cooling upper
header. Furnace intersecting surface is 3170×5290mm2 and
the elevation of top furnace is 28877mm. The membrane water wall is
made up of φ60×5 and 6×45 welding steel flat. The combustion chamber is
made of φ60×4 steel tube and welded with pin to fasten refractory
material. The upper part of combustion chamber connects with furnace
membrane water wall. The lower part connects with water cooling wind
chamber and water cooling air distributor. The water cooling wind
chamber is made up of φ60 steel tube and welded with pins to fasten the
refractory material. The water cooling distributor is welded with
φ60 steel tube and 6X45 steel flat. The small holes on the steel flat
connects with the funnel cap.
The
furnace divides left, right, front and back water circulation circuit.
The steam leading tube is made up of φ133×5 and φ108×4.5 steel tube. The
downcomer is made up of φ108×4.5 steel tube. Install the blowdown valve
under the lower header to periodic blow down.
Concentrated solar power (Concentrating Solar Power) referred to as CSP, to be exact "concentrated solar power."
