According to wikipedia.org, induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an induction coil that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold, silver, aluminum, or carbide.
Induction heating applications include hardening, tempering, annealing, stress relieving, brazing, soldering, shrink fitting, heat staking, pipe heating, pipe coating, wire, rod, cable and tube processing.
To do induction heating, we need to decide on induction heating equipment that is suitable with the application.
After selecting the induction heating equipment, then the next step is to select appropriate cooling system. The cooling system can be opened or closed system.
In case where an opened cooling system is used, this means that cooling tower type needs to be selected before going further into details.
There are several type of cooling towers that can be used for cooling an induction heating system; mechanical draft, atmospheric, hybrid, construction characterized, air-flow characterized, and shaped characterized cooling towers.
If the existing cooling tower will be used as the cooling equipment, there are some factors that needs to be considered before making any decision.
Here are those consideration factors:
- existing cooling tower capacity
- water quality
- available space for piping modification
- capital cost
- operating and utility cost
- wastewater quality and wastewater treatment capacity
