The system is designed to take as much work as possible out of the turbine. The exit Mach number is very low and the exit pressure is very close to the ambient. such as diesel engine and gas turbine based power plants. Recent deregulation and privatisation of electricity generation industries throughout the world has. for gas, oil, metallurgical and chemical industry, power generation and integrated power Gas turbine power stations based on gas turbines rated at 22/25 MW.
Therefore, a heat exchanger can be placed between the hot gases leaving the turbine and the cooler gases leaving the compressor. This heat exchanger is called a regenerator or recuperator.. Gas Turbine Cycle — Intercooling When using multistage compression, cooling the working fluid between the stages will reduce the amount of compressor work required.
The compressor work is reduced because cooling the working fluid reduces the average specific volume of the fluid and thus reduces the amount of work on the fluid to achieve the given pressure rise. To determine the intermediate pressure at which intercooling should take place to minimize the compressor work, we follow the approach shown in Chapter 7.
During inter cooling the compressor final exit temperature is reduced; therefore, more heat must be supplied in the heat addition process to achieve the maximum temperature of the cycle. Regeneration can make up part of the required heat transfer. This temperature can be controlled by providing Air in Excess of the Amount required to Burn the Fuel in the combustor. As a consequence, the gases exiting the combustor contain Sufficient Air to support the Combustion of Additional Fuel.
The expansion is then completed in the second turbine from State b to State 4. The cycle pressure ratio is 8. The temperature at the inlet to the turbine is K. Calculate a. The gas temperature at the exit of the compressor and turbine b. Calculate the performance parameters of the cycle. To generate electricity, the gas turbine heats a mixture of air and fuel at very high temperatures, causing the turbine blades to spin.
The spinning turbine drives a generator that converts the energy into electricity.
The gas turbine can be used in combination with a steam turbine—in a combined-cycle power plant—to create power extremely efficiently. Heavy-Duty Gas Turbine Overview. Play Video How a Gas Turbine Works Take a closer look at how a gas turbine, the heart of a power plant, turns fuel into power.
What is a Gas Turbine? Improve Performance with Digital. How the Gas Generator Produces Electricity To generate electricity, the gas turbine heats a mixture of air and fuel at very high temperatures, causing the turbine blades to spin.
Air-fuel mixture ignites. The result is a combined gassteam cycle. Recent developments in gas-turbine technology have made the combined gassteam cycle economically very attractive.
The combined cycle increases the efficiency without increasing the initial cost greatly. Consequently, many new power plants operate on combined cycles, and many more existing steam- or gas-turbine plants are being converted to combined-cycle power plants.
Advantages of Combined Cycle Power Plant The efficiency of the combined cycle plant is better or higher than the turbine cycle or steam cycle plant. Higher cost longer start-up less responsive to power demands shrill whining noise. Flag for inappropriate content.
