Waste Heat from Cogeneration
Cogeneration is a common and increasingly promoted method of optimising energy efficiency in power production. The waste heat from power production can easily be converted into useful energy, used for heating in winter and most notably for cooling applications in summer (Combined Cooling, Heating, and Power generation often referred to as trigeneration).
Characteristics of trigeneration applications:
- Driving energy is provided as waste heat from incineration processes in electricity production
- Achievement of longer operating times in heat-driven cogeneration plants through the use of exhaust heat for cooling during summer months
- Prolonged annual load duration curve of the heat requirement, enabling longer cogeneration plant operating times with higher utilization
- Additional utilization of heat with electrically driven cogeneration plants, making it possible to achieve annual utilization rates that may be required by national subsidy schemes
- The piping in modern buildings can be used for heating and cooling applications in equal measure
- Reduction of the fuel consumption of diesel generators in off-grid applications through the use of waste heat to operate absorption chillers
- Greater latitude in the usage options for the electricity produced from diesel generators in off-grid applications by reducing electrical power consumption for cooling through the use of absorption chillers
The scheme below shows an example of a trigeneration cooling system configuration.
YAZAKI provides the chiller/heater unit only. If you need more information about other equipment such as cooling towers, valves etc. please contact the manufacturers of this equipment.
