The correct answer is option 'D', which states that the evaporator in a boot-strap air evaporative cooling system is provided between the second heat exchanger and the cooling turbine.
Let's break down the explanation into the following sections:
1. Introduction to a boot-strap air evaporative cooling system:
- A boot-strap air evaporative cooling system is a type of cooling system that utilizes the evaporation of water to provide cooling.
- It is commonly used in gas turbine power plants to increase the power output and efficiency of the turbine.
2. Components of a boot-strap air evaporative cooling system:
a) Combustion chamber: This is where the fuel is burned to produce hot gases.
b) First heat exchanger: Also known as a recuperator, it is used to recover heat from the exhaust gases and transfer it to the incoming air.
c) Secondary compressor: This compressor further compresses the air before it enters the evaporator.
d) Second heat exchanger: Also known as a pre-cooler, it further cools the air before it enters the evaporator.
e) Evaporator: This is where water is evaporated to cool the air.
f) Cooling turbine: This turbine is used to extract work from the air stream and provide additional cooling.
3. Explanation of the correct answer:
- The correct answer, option 'D', states that the evaporator is provided between the second heat exchanger and the cooling turbine.
- This means that the air, after being cooled in the second heat exchanger, enters the evaporator where water is evaporated to further cool the air.
- The cooled air then passes through the cooling turbine, where work is extracted from the air stream, resulting in additional cooling.
- This arrangement allows for efficient cooling of the air before it enters the turbine, improving the overall performance of the system.
In conclusion, in a boot-strap air evaporative cooling system, the evaporator is provided between the second heat exchanger and the cooling turbine. This arrangement allows for effective cooling of the air before it enters the turbine, resulting in increased power output and efficiency of the system.
