Optimise heat recuperation• Waste heat is often at lower temperatures available
⇒ LT-heating system is necessary– Too big radiators– Ventiloconvector– Floor and wall heating – Concrete mass activation
• Waste heat at too low temperatures can be upgraded with heat pumps
• Process: Pinch-analysis

Waste heat can be reused• Large process: Pinch-analysis• Boilers and ovens :
– Heat recuperation with external heat exchangers:
• Economisers• Flue gas condensors• Central heating
– Air Preheating :• External Preheater• Regenerative and recuperative
burners
• If time of heat demand and heat supply are different : consider heat stocks

Efficient heating technology• Condensing boiler
– CH4 + 2 O2 → CO2 + 2 H2 H22OO– Use latent heat in water of flue gasses – 5..15% gain on gas consumption is possible (if low temperatures are being
used) • Heat Pumps
– Use of environment heat or waste heat (max. ∆T = 50 °C ⇒ LT!!)– Electricity consumption with COP 3-6
• Cogeneration of Heat and Power – Use waste heat from electricity production– Saves often about 20% compared to separate production

Air heating in industrial halls• Heated medium = air
– If lots of ventilation ⇒ lots of heat losses– Creates convection ⇒ dust circulation– Stratification of heat against the ceiling
• Can be remediated with ventilators to push hot air down
• Conventional air heaters : global efficiency• Condensing air heaters
– 10% more efficient then conventional – 30% additional cost

Conclusions : an Energy audit : Why ? • Internal audit (part of Energy Management)
– Search for economical energy saving potentials⇒ Saving energy costs
- Empowerment and implication of own personnel ↑⇒ General support for structural energy Management;
• External audit– External expert has a different point of view on the process– Energy expert has
• specific knowledge on techniques to reduce energy consumption• an eye for easy win-win situations• is not implicated in the history of the company• knows the legal and economical situation
