Maintain Heat exchanger fundamental
Equipment for transferring heat are used in essentially all the process industries, and the engineer should be acquainted with the many different types of equipment employed for this operation, especially shell and tube heat exchangers, the most extensively used in the industry. Therefore, a deeper knowledge of such equipment is essential for the personnel who might be involved in the design, operation, maintenance, testing, or in specifying and purchasing of such equipment.
The objectives of this course are:
- To gain basic knowledge about heat transfer.
- To acquire knowledge about the basics of heat exchangers.
- To become familiar with the different types of heat exchangers.
- To gain knowledge of parameters affecting the performance of heat exchangers.
- To go through a design procedure for a shell and tube heat exchanger.
- To learn about the mechanical and thermal features of shell and tube heat exchangers.
- To gain a deeper understanding of fouling, corrosion and induced vibrations problems in heat exchangers.
- To become familiar with knowledge necessary for the maintenance and troubleshooting of shell and tube heat exchangers.
- To learn about TEMA standards.
