Reduce your costs with efficient re-use of energy
The application of heat recovery techniques can significantly reduce energy consumption, running costs and carbon emissions.
Heat recovery is the collection and re-use of heat arising from any process that would otherwise be lost. Oakes Energy can help you identify sources of waste heat and then design and install systems to use these to improve the energy efficiency of heat generation.
Sources of ‘waste’ heat
You’re likely to have sources of ‘waste’ heat in your building whether you are in a house (e.g. from waste hot water or heating) or office (e.g. from the heating or ventilation systems) or a factory (e.g. in an industrial drying process or compressed air system).
Waste heat from the following common sources often presents opportunities for cost-effective heat recovery:
- Ventilation system extracts
- Boiler flue gases
- Boiler blow-down
- Air compressors
- Refrigeration plant
- High temperature exhaust gas streams from furnaces, kilns, ovens and dryers
- Hot liquid effluents
- Power generation plant
- Process plant cooling systems.
Where it’s possible, the most cost-effective use of waste heat is usually to improve the energy efficiency of the heat generating process itself.
Improving the energy efficiency of heat generation
Common uses (or ‘sinks’) for recovered heat include:
- Pre-heating combustion air for boilers, ovens, furnaces, and so on
- Pre-heating fresh air used to ventilate the building
- Hot water generation, including pre-heating boiler feed water
- Space heating
- Other industrial process heating/pre-heating
- Power generation
In most cases, heat recovery is far more efficient when the heat source and heat sink are physically close together and occur at the same time – Oakes Energy can advise.
