Regenerative-Reheat Cycle in Mechanical Engineering
Regenerative-Reheat Cycle is a thermodynamic cycle used in power plants to increase the efficiency of a gas turbine by increasing the temperature of the gas entering the turbine. In this cycle, air enters the compressor at 1 bar and 300 K and goes through multiple processes before exiting the turbine.
Compression Process
The air is compressed in two stages with intercooling between them. The air leaving the first stage of compression is cooled down to 290 K at 4 bar pressure in the intercooler. The compressed air is then further compressed up to 8 bar in the second stage of compression.
Regeneration Process
The compressed and heated air leaving the second stage of the compressor goes through a regenerator having an effectiveness of 0.80. The regenerator is a heat exchanger that recovers the heat from the hot gas leaving the turbine and transfers it to the cold air entering the compressor. This process increases the temperature of the air entering the combustion chamber, which in turn increases the efficiency of the cycle.
Combustion Process
The air leaving the regenerator is then mixed with fuel and burned in the combustion chamber. The combustion process yields a temperature of 1300 K at the inlet to the turbine. The hot gas leaving the combustion chamber enters the turbine and expands, which produces work to drive the compressor and generator.
Reheat Process
The gas leaving the turbine is then reheated in a heat exchanger before entering the second stage of the turbine. This process increases the temperature of the gas and hence increases the efficiency of the cycle.
Conclusion
The Regenerative-Reheat Cycle is a thermodynamic cycle that increases the efficiency of gas turbines. The cycle includes compression, regeneration, combustion, and reheat processes. The compression process involves two stages of compression with intercooling. The regeneration process involves a heat exchanger that transfers heat from the hot gas leaving the turbine to the cold air entering the compressor. The combustion process involves mixing the air leaving the regenerator with fuel and burning it in the combustion chamber. The reheat process involves reheating the gas leaving the turbine before entering the second stage of the turbine.
