Energy Cost of Waterside Fouling In Industrial Equipment
Energy is by far the largest component of the total life cycle cost of most energy-using equipment!
A good proactive/predictive maintenance program, with regards to waterside fouling, reduces unplanned shutdowns, astronomical energy and operational costs, lower maintenance budgets and maintaining optimum operating efficiency in equipment.
The effectiveness of heat exchangers is reduced with the increase in thermal resistance; even a minute layer of fouling reduces thermal conductivity.
Plainly stated, the growing cost of maintenance is a serious business problem. According to DuPont, "maintenance is the largest single controllable expenditure in a plant: in many companies it often exceeds annual net profit."
One major U.S. automotive manufacturer has a maintenance staff of between 15,000 and 18,000, all plants combined. They say, "85% to 90% is crisis work" (breakdown).
Due to the:
1. Introduction of new water continuously,
Fouling cannot be avoided in everyday situations, it can only be minimized.
Two basic and effective ways to reduce energy costs that apply to all energy production, distribution and end-use categories are:
1. To reduce the load or need for energy
