3. INTRODUCTION-
 Brayton cycle is the cycle on which gas turbine plant works.
 It is a constant pressure cycle for a perfect gas.
 It is also called as Joule cycle.
 The heat transfers are achieved in revesible constant pressure heat
exchangers.

4. COMPONENTS-
 Compressor
 Combustion chamber
 Gas turbine
 Heat exchanger(only for closed type)

5. FUNCTION OF EACH COMPONENT-
Component Function
Compressor increases pressure and temperature
Combustion Chamber burns the fluid
Gas Turbine mechanical work production
Heat exchanger supplies heat from exhaust of Turbine
to inlet of compressor

6. TYPES-
 Open type- In this Brayton cycle,the outlet of Gas turbine is not
recycled.
 Closed type- In this Brayton cycle,the outlet of Gas turbine is
recycled and there is implementation of heat exchanger .
 Reverse type-The direction of flow is opposite of Brayton cycle.The
purpose is to move heat from colder body to hotter body with the
supply of external work.

8. Reversed Brayton Cycle

9. THERMODYNAMIC ANALYSIS-

11. Actual Brayton Cycle-

12. IMPROVEMENT OF ACTUAL BRAYTON CYCLE
 Brayton Cycle with Regeneration

14. Reheat Brayton Cycle  Intercooled Brayton Cycle

15. Brayton Cycle with intercooling,regeneration and reheat

16. ADVANTAGES
Higher power to weight ratio
Compact
One direction motion-vibration
Fewer Moving Parts
Better Reliability
Variety of fuels
Low Emissions
DISADVANTAGES
Starting Problem
High cost
Overall efficiency of turbine is low.
Sensitive to Component efficiency.

17. Applications
Jet Engine
Solar Concentrator
Radioisotope
Reactor

18. CONCLUSION-
 The most effective utilization of Brayton cycle till found is jet
engine.
 Scientist are still in in research to implement this cycle for
utilization of solar energy.
 Variety of fuels makes it suitable for commercial use.
