In Ventilation and Emission-Control Systems…4 Factors to Lower Energy Costs

摘要

The mathematics for properly designing ventilation and emission-control systems have been around for quite awhile, but our studies of hundreds of systems show that many are wasting energy, while still lacking capacity to meet applicable codes and process objectives. There's a lot of money on the table in operating costs for these systems. More than 40 percent of the energy consumed in most manufacturing plants is used to power fans, pumps, and ventilators. In some cases, the annual operating costs of a system may actually exceed the equipment's initial capital cost within two years of installation. There are opportunities for improvement, and these reside in the air power equation.
