Reheating is applied in a gas turbine in such a way that it increases the turbine work without increasing the compressor work or melting the turbine materials. A reheater is generally is a combustor which reheat the flow between the high and low pressure turbines. In jet engines an afterburner is used to reheat.

In respect to this, what is reheating and regeneration of gas turbine?
The Intercooling, Reheat, Regenerative Gas-turbine Cycle Reheating in thermodynamic process refers to an approach to build turbine work without variation in the compressor work from which the turbine is developed.
what is intercooling in gas turbine? In a gas turbine, the job of compressor is to adiabatically compress the air before going inside the combustion chamber. Intercooling is a process in which the efficiency of compressor is enhanced by compressing the gas with the help of two compressors keeping an intercooler in between.
In respect to this, what is gas turbine regeneration?
Regeneration is a process in which high temperature gases at the exit of turbine are utilized for heating the air which are coming out from the compressor and before entering the Combustion Chamber.
How efficient is a gas turbine?
Turbine efficiency is the ratio of actual work output of the turbine to the net input energy supplied in the form of fuel. For stand-alone gas turbines, without any heat recovery system the efficiency will be as low as 35 to 40 per cent.
Related Question AnswersWhat is reheat cycle?
Rankine cycle with reheat The purpose of a reheating cycle is to remove the moisture carried by the steam at the final stages of the expansion process. In this variation, two turbines work in series. The first accepts vapor from the boiler at high pressure.How can gas turbine be improved efficiency?
Therefore, gas turbine efficiency can be improved by cooling the inlet air. This is especially effective in hot, dry climates. A significant benefit of turbine air inlet cooling is that it can reduce (or eliminate) fuel efficiency reduction by evaporative cooling the inlet air to the wet bulb temperature.What is the use of reheater in a gas turbine?
A reheater is generally is a combustor which reheat the flow between the high and low pressure turbines. In jet engines an afterburner is used to reheat. It is attached at the exhaust of the turbine. As a result the thrust is increased.Which fuel is used in gas turbine power plant?
natural gasWhat are the advantages of reheat cycle?
The advantages of using a reheat cycle are higher thermal efficiency, reduced feed water pump power, smaller condenser, smaller boiler, long life of the turbine and less handling of the fuel and firing requirement.Why reheating of steam is required?
The main purpose of reheating is to avoid excess moisture in steam at the end of expansion to protect the turbine. But it need not improve the cycle efficiency.What is open cycle gas turbine?
A simple open cycle gas turbine consists of a compressor, combustion chamber and a turbine as shown in the below figure. The compressor takes in ambient fresh air and raises its pressure. The heated gases coming out of the combustion chamber are then passed to the turbine where it expands doing mechanical work.What is regenerative cycle?
The Regenerative Cycle. Regeneration in thermodynamics process refers to a method where the certain quantity of heat abstracted from the steam is utilized to heat the water. The regeneration process occurs between the stages of turbine and pump respectively.How does Brayton cycle work?
According to the principle of the Brayton cycle, air is compressed in the turbine compressor. The air is then mixed with fuel, and burned under constant pressure conditions in the combustor. The resulting hot gas is allowed to expand through a turbine to perform work.What does the regenerative system on a gas turbine do?
The Regenerative Gas-turbine Cycle. Regeneration in thermodynamics process refers to a method where the certain quantity of heat abstracted from the steam is utilized to heat the water. The regeneration process occurs between the stages of turbine and pump respectively.What is an intercooler on a diesel engine?
An intercooler is a special piece, usually placed on Turbocharged or Supercharged engines. It's purpose is to round up the air compressed by the turbo and supercharger, and then strategically cool it. The key to having an extremely functional Turbo Diesel Intercooler is all in the science.What is a charge air cooler?
About Charge Air Coolers A charge air cooler is used to cool engine air after it has passed through a turbocharger, but before it enters the engine. The idea is to return the air to a lower temperature, for the optimum power from the combustion process within the engine.What are the 3 main components of gas turbine?
Major components include the compressor, combustion system, gas producer turbine, and power turbine.Which turbine has highest efficiency?
