The right engine for each individual output requirement



Cogeneration of heat and power (CHP)CHP systems utilize the waste heat incurred during engine operation to generate overall plant efficiencies of more than 90%.

HE 1Mixture intercooler

HE 2Oil exchange heater

HE 3Engine jacket water heat exchanger

HE 4Exhaust gas heat exchanger



Jenbacher cogeneration plants achieve engine efficiencies of up to 90%The generated power is …• utilized by the individual facilities (e.g., hospitals)• fed into the public power grid

The thermal energy can be used for …• generating heating water (municipal district heating networks)• process heat, and/or steam production for different industries like:

- food- beverage (e.g., breweries)- dairies- plastics- pharma- petrochemicals



Typical Jenbacher multi-engine design forflexibility in heat and power supply



Trigeneration of heat, cooling and power

Refrigeration is required for …• air conditioning (e.g., hotels, conference centers, office buildings, airports)

• industrial processes (e.g., food, chemical, electronic)

Absorption chiller technology offers the most established and economicsolution for reduced emission air conditioning systems.



Trigeneration concept: Jenbacher gas enginesin combination with absorption chillers

• Maximum total fuel efficiency• Elimination of HCFC/CFC refrigerants• Reduced overall air emissions



GE’s cogeneration/trigeneration systems offer numerous advantages• High electrical efficiencies of up to 43%

• Overall efficiencies of over 90%

• High flexibility in adaptation to customers‘ heat , power and cold demands

• Minimum emissions through LEANOX® combustion

• Small footprint

• Fuel flexibility through special engine design

• Maximum operational safetyand availability

• Low investment costs



GE’s Jenbacher cogeneration systems continue to lead the way in CHP technology

• More than 4,250 Jenbacher cogeneration / trigeneration plants worldwide

• Over 4,730 MW total electrical output

Increases in energy costs, environmental concerns and energy demands will continue to promote the future growth of CHP technology in the world.

Backup



Absorption chillers are an ideal alternativeto conventional refrigerationWorking principle• Two substances (e.g., water and lithium bromide salt) are separated

through the addition of heat (desorption)

• They are then reunited through heat removal (absorption)

• Desorption and absorption at varying pressure conditions in a vacuum range:- Desorption: 80 mbar- Absorption: 10 mbar

• Water and lithium bromide salt generate chilled water in the temperature range from6 to 12°C, ammonia and water are used for low temperature chilling down to -60°C



Absorption chiller: Step 1 – Evaporator

Source: THERMAX

Water (refrigerant) evaporates at 4.5°C due to high vacuum (8 mbar abs.) thus cooling chilled water to 6°C.



Absorption chiller: Step 2 – Absorber

Source: THERMAX

Highly concentrated LiBr solution absorbs the evaporated water due to high hygroscopic affinity.



Absorption chiller: Step 3 – Generator

Source: THERMAX

As the LiBr solution becomes diluted by absorption, it must be re-concentrated by means of an outside heat source.



Absorption chiller: Step 4 – Condenser

Source: THERMAX

The water vapor is brought back to the liquid phase in the condenser and is again available for the circuit.



Energy savings through CHP technology

Primary energy savings: roughly 40%
