3. MicroTurbines are new type of combustion
turbine used for stationary energy generation.
The concept is evolved from automotive and
truck turbochargers, auxiliary power units (APU)
for airplanes.
Approximately the size of a refrigerator with
outputs of 25 kW to 500 kW.
They provide not only electricity , but also the
thermal energy to provide for all heating and
cooling needs

12. Unrecuperated
• Compressed air is mixed with
fuel and burned under
constant pressure conditions.
• Efficiency 15%.
Recuperated
• A sheet metal heat exchanger
(recuperator) recovers temperature
of the air stream supplied to the
combustor.
• Efficiency 20~30%.

13. • Small number of moving parts
• Compact size
• Lightweight
• Good efficiencies in cogeneration
• Low emission
• Can utilize waste fuels
• Long maintenance interval
• No vibration
• Less noise than reciprocating engines

15. Peak shaving and base load power (grid parallel)
Combined heat and power (co-generation)
Distributed power generation
Stand-alone power
Backup/standby power
Primary power with grid as backup
Micro grid
Resource recovery
Transportation applications
16. Heat loss due to the high surface to volume
ratio
Cooling problems
manufacturing the components (turbine
blades)
Generation of thermal stresses
Design of air bearings

17. Micro turbine can use low grade of fuel very effectively
like waste gases, sour gases etc.
Thus micro turbine gives chance of low fuel cost and less
emission.
The dimensions of micro turbine comparatively small by
which it can be installed at field where power is consumed.
Micro turbine is also effective in CHP operation.
In India the micro turbine is quite useful.
The power shortage effect can be solved using micro
turbine, using fuels like biogas, etc.
