What did the Magnum Ventures energy audit cover?

It covered boiler efficiency, steam and turbine performance, auxiliary power, pumps, cooling towers, motors, power factor, harmonics and financial evaluation of energy-conservation measures.

Were 29% savings achieved or identified?

The available case-study data supports describing 29% as identified or projected saving potential. Actual savings require implementation and measurement and verification.

What was the largest identified opportunity?

Correcting low main-steam temperature through superheater repair or modification represented the largest single estimated financial opportunity.

Why were pumping systems a priority?

Water-pumping systems represented approximately 59% of auxiliary electricity, and measured pump efficiencies indicated substantial operating and equipment-selection opportunities.

What electrical improvements were recommended?

Recommendations included selected motor replacement, feeder-level power-factor correction, capacitor installation and review of harmonic distortion.

How should energy-audit measures be prioritised?

Measures should be prioritised using verified saving potential, implementation cost, production risk, maintenance requirements, operational practicality and measurement capability.
