How are gas turbine blades designed?
Designing a turbine blade involves a thorough analysis of various factors, including load conditions, material properties, and aerodynamic performance.
The turbine blade is subjected to high centrifugal forces during operation.
The blade must be designed to withstand these loads without failure..
How does a micro gas turbine work?
In micro turbines, the compressor draws the air into a recuperator, which acts as an air-to-air heat exchanger, recovering the heat from exhaust gas.
Heating of the combustion air increases the micro turbine's electric efficiency.
The heated air is passed into the combustor chamber, into which fuel is also injected..
How to design a micro gas turbine?
The combustion chamber is designed using biogas as a fuel.
The design principle is based on the constant pressure, enthalpy addition process.
The dimensions of the combustor are calculated based on different empirical formulae.
The air mass flow is then passed round across the zones of the combustor..
What are most micro turbine units designed for?
Most micro-turbines are designed to burn natural gas.
A packaged system will comprise the micro-turbine generator, a gas compressor to provide natural gas at the pressure required by the turbine combustion chamber, a solid-state grid interface, and, in many cases, a waste heat-recovery system..
What are the components of a micro gas turbine?
Micro turbines typically comprise an air compressor, combustor, turbine, alternator, recuperator and generator (Fig. 17.5).
Micro turbines have a single shaft on which the compressor, turbine and generator are fixed..
What is the concept of micro turbine?
Microturbines are small gas turbines coupled to their generators.
They are used to produce both electricity and heat and are available in a range of 25–500 kW and efficiency ranges between 20% and 30%..
- Gas turbines are composed of three main components: compressor, combustor, and turbine.
In the compressor section, air is drawn in and compressed up to 40 times ambient pressure and directed to the combustor section, where fuel is introduced, ignited, and burned. - In micro turbines, the compressor draws the air into a recuperator, which acts as an air-to-air heat exchanger, recovering the heat from exhaust gas.
Heating of the combustion air increases the micro turbine's electric efficiency.
The heated air is passed into the combustor chamber, into which fuel is also injected. - The analysis of turbine blade mainly consists of the following two parts: Structural and thermal analysis.
The analysis is carried out under steady state conditions using ANSYS software.
The study has been conducted with two different materials Inconel 718 and Titanium T6.
