Analisis Kinerja Alat Penukar Kalor Jenis Shell and Tube Pendingin Aliran Air pada PLTA Jatiluhur

Abstract

This paper presented a shell and tube heat exchanger with type BFU, that is by making its performance
analysis. Result of this evaluation will be compared to appliance with performance prediction heat
exchanger second with type BFS, besides result of the prediction will be compared to result of examination
of second type which done by in PLTA JATILUHUR. This analysis require to be done by because heat
exchanger with type of BFU often happened leakage especially at rear head because at the shares quickly
happened conglomeration of deposit. The detailed design on heat exchanger components was done based
on Standards of Tubular Exchanger Manufacturers Association (TEMA). The heat exchanger type that was
chosen is BFS type with two shell and two tube passes. According to the chosen heat exchanger geometry,
the fluid flow in shell side was analyzed by CFD software to find flow pattern and properties of this fluid.
The result of fluid flow analysis with CFD software is accurate enough or close to the theoretical analysis
result. Therefore, it is important to analyze fluid flow along the shell in different surface of cross section with
certain spacing to find completed conditions of fluid. More detailed design and analysis of heat exchanger
is needed to have a heat exchanger design that can be fabricated and have good performance.
