Energy Audit Uncovers Major Energy Savings for Paper Mill Jerry L. Aue, Aue Energy Consulting Sue Pierce, Johnson Corporation ABSTRACT Energy and financial savings are presented through the results of a recent Stora Enso North America – Stevens Point Paper Machine No. 34 (PM34) dryer section feasibility study and rebuild.
The purpose, scale, and nature of the industry all influence the type of industrial energy audit that is undertaken. An industrial energy audit can be divided into two categories [5] based on these criteria: Detailed audit (diagnostic audit) and preliminary audit (walk-through audit) A preliminary energy audit is known as a walk-through audit.
The plant mainly relies on its 12 MW captive power plant (CPP) to meet its electricity requirements. This project brings out in a holistic and simple fassion, the broad frame …
The only solution that seems to be effective is to replace existing equipment with energy-efficient equipment, energy-efficient lighting, and power-driven equipment. In order to proceed with this solution, an energy audit is required for the whole building. The focus of this study is an energy audit at a cement factory.
energy audits in industrial facilities so that even small enterprises can incorporate auditing into their overall energy management strategies. 1 2 in-house energy audit Consider the following simple definition of an energy audit: "An energy audit is developing an understanding of the specific energy-using patterns of a particular facility."
