IELTS Model Answer
The diagram illustrates the process involved in production of electricity through Ocean Thermal Energy Conversion (OTEC) System.
Overall, the process involves electricity production by utilizing sea water in different ways. The sea water is used to generate electricity and drinking water through OTEC system.
The sea water is divided according to its temperature which depends on its depth. Water on the surface of the sea is termed as warm sea water and water 1000m below is called cold sea water having a temperature of 5 degree Celsius. The warm sea water is vaporized by energy from sun. These water vapors are utilized to run turbine and generate electricity. Moreover, the warm sea water is evaporated in an evaporation chamber which produces vapors to turn on turbine as well as salt as a waste.
On the other hand, cold sea water and the salt residue from evaporation chamber are used in condensation chamber. The water vapors that were utilized for creating electricity in turbine are collected and condensed into drinking water in the condensing chamber. The last step involves removal of the salty water from the OTEC system.
