This essay focuses on Asset Using Solar Energy. the solar portion of our plant. References three through five are the general information
1 Reference Review The main reference that will be used in this paper is, “Performance assessment of an integrated solar cycle in southern Algeria” written and edited by Lazhar Achour, Malek Bouharkat, Omar Behar.[1]
This is the power plant design and information that was used to complete this project. The second reference used in this project is Chapter eight of the textbook Solar Pyrolysis: Converting Waste Into Asset Using Solar Energy by M.U.H. Joardder, P.K. Halder, M.A. Rahim, and M.H. Masud. [2]
was used to learn more about the solar portion of our plant. With solar becoming cheaper the appeal of creating a solar power plant is growing by the day.
In the performance assessment of this power plant the authors claim that the ISCC is the most efficient way to convert solar energy into electricity. [1] The reason why
this location was chosen for the proposed plant is because of known temperature and solar radiation reading for this location. Some location information for Tamanrasset Algeria: the climate is a hot dessert; its elevation is 1377 meters above sea level; the max, min, and average temperatures are 30, 12.9, and 22.9 degrees
While this plant is only a concept and not an actual implemented plant the authors of the journal have laid out the full design of the plant based on known thermodynamic properties used in similar plants with similar components. This plant is set up with two SGT- 800 gas turbines, one 3 SST-900 Steam turbine, and a solar field (Parabolic Trough Collectors) with two heat recovery steam generators (HRSGs) in parallel with the field.
with their design and calculations the solar portion can have up to 14.4 percent solar to electricity efficiency with an overall plant thermal efficiency of up to 60 percent. 1.3 Solar Field and HRSGs For the solar power the design of the solar field uses parabolic troughs for the heat collection and two heat recovery steam generators to add to the heat of the cycle when the sun is out and in turn this adds electricity to the entire system.
The textbook from reference 2 defines that, “Parabolictrough solar concentrating systems are parabolic-shaped collectors made of reflecting materials”.[2] It goes on to describe that the reason for its parabolic shape is to reflect the sun’s rays to a central point called the receiver and this raises the temperature of water and then the steam is turned into to energy. Another feature of the parabolic tough is tfield. The formal definition of the HRSG is that a
generator is a high-efficiency steam boiler that uses hot gases from a gas turbine for reciprocating engine to generate steam in a thermodynamic Rankine Cycle.”[1] for our plant instead of taking the heat from the gas turbine it is taking the heat generated from the solar field. 1.4 The SGT-800 (Gas Turbine) This plant uses two SGT-800 gas turbines with 40MWe for each turbine [1]. The engine, as described by Siemens, is a single shaft engine with a two-bearing motor. Following that is a 15-stage compressor and a 3-stage turbine.[3]
an rpm of about 6,600. For fuel intake, the turbine can take gas only, liquid only like Diesel No.2, or both gas and liquid.[3] A final important feature of the turbine is that it has a dual-fuel Dry Low Emission (DLE) combustion system.. 4 1.5 The SST-900 (Steam Turbine) This plant uses one SST-900 steam turbine with 80MWe power production. This design has a steam turbine geared for high pressure or back pressure, and a low-pressure steam turbine or condenser. Both turbines drive the generator that is install between them.[4] All three of these models are distribute by General Electric (GE). A Skeleton for our ISCC Power Plant can be show below
