This document discusses Elliott Microturbines and their 100kW TA100 combined heat and power (CHP) system. It provides an overview of microturbines compared to conventional generators, describing their higher rpm and use of a permanent magnet generator. The microturbine CHP package is turnkey and integrates components like a heat exchanger. The document also summarizes an installation of 15 TA100 microturbines to provide 1.5MW of power and hot water to a large facility, reducing electrical demand charges. It includes diagrams of the microturbine system and CHP block.

7. Decision Factors
• High Demand Charges
– Peak Demand 8- 9 MW
• Requirement to Make Facilities Energy
Efficient.
• Existing Boiler System was to be re-
worked or replaced.
• Incentives for DG technologies

8. Electrical Demand
• Total facility demand is above 8 MW
– Demand charges are high.
– Goal is to reduce demand to less than 7
MW
– Reduction is accomplished through
• High efficiency light fixtures and appliances
• Microturbine demand reduction 1.5 MW

9. Thermal Demand
• High Pressure, High Temperature Water
supplied in district heating fashion
– Domestic Hot Water
– Heating
– Chilled Water
– Ice Storage System

10. The Project
• Bank of 15 ea. 100kW CHP Microturbine
Gensets took on the boiler load.
• Boiler re-worked and used as redundant
system.
• Fuel Supply
– Natural Gas – Interruptible Rates
– Back-up fuel supply = Propane

11. Operation
• Operation is scheduled based on Thermal
Demand and Peak electrical rates.
• Winter
– Winter rates the hot water or thermal load sets
the demand of the microturbine.
– Peak rates lower in winter.
• Summer
– In Summer time electrical peak sets demand.
HEX bypass when hot water is not needed.
Penalties
– Peak rates higher in Summer.

14. 1.5 MW Microturbine

• Hot water is supplied in
district heating fashion
– Domestic Hot Water
– Heating
• 1.5 MW used to base
load facility.

25. Microturbine System

26. Microturbine System
• 1. Engine inlet air to Compressor
• 2. Air is compressed by Impeller.
• 3. Compressed air is sent to Recuperator.
• 4. Duct directs compressed air into Recuperator
• 5. Recuperator heats the compressed air using exhaust energy.
• 6. Compressed and now heated air is directed towards Combustion Chamber
• 7. Heated Air is mixed in the Combustion Chamber with natural gas and ignited.
• 8. Exhaust from combustion process is directed through turbine wheel causing
alternator
• to rotate, which provides an output of 105 kW.
• 9. Ehaust is passed to the Recuperator to heat the Compressor delivery air.
• 10. Exhaust exits the Recuperator.

27. Power Electronics
• With Power Electronics, a microturbine is a self-
induced or line-induced inverter power system.
• Microturbine Starting Uses 24 VDC battery system or
electric grid.
• Digital Control Provides Reliable and Precise High
Quality Electrical Output
• Over/Under Voltage, Over/Under Frequency and
Over Current Protection While in Grid or Island Mode
• Power Factor Adjustment (0.8 Leading to 0.8
Lagging)

28. • Increases in the inlet air temperature will
decrease the performance of a microturbine
because of the lower air density.
