Abstract
Cooling Water Heat Exchanger (CWHE) merupakan sebuah alat yang memiliki fungsi untuk mendinginkan Fluida air (Air Demin) yang memiliki temperatur tinggi akibat melewati sistem pelumasan pada bantalan dan komponen - komponen Turbin gas.
Tahapan dalam penelitian ini meliputi empat bagian, yakni : Pertama, Menentukan asumsi desain awal terkait bentuk dan ukuran shell and tube berdasarkan standar TEMA (Tubular Exchanger Manufacturers Association) dan kondisi existing., Kedua Menghitung perancangan desain Heat Exchanger tipe shell and tube secara analitis., Ketiga Melakukan pengoreksian desain analitis dengan metode iterasi menggunakan Microsoft Excel hingga besarnya nilai mendekati < 5% dan yang terakhir menghitung menggunakan Software HTRI.
performa cooling water heat exchanger tipe Shell and Tube mendapatkan nilai sebesar 65,307%, laju perpindahan panas sebesar 10000000 W. Hasil desain dan dimensi dengan menggunakan standar TEMA (Tubular Exchanger Manufacturers Association) meliputi diameter tube sebesar 1 in (BWG 14), jumlah tube sebanyak 2156 buah, diameter shell sebesar 1,568 m, baffle spacing sebesar 0,6375 m, jumlah baffle sebanyak 16 buah, Besarnya koefisien perpindahan panas seluruhnya sebesar 1686,645 W/m2K dengan nilai koreksi 0,7918%. Sementara berdasarkan perhitungan numerik menggunakan software HTRI Design and Rating didapatkan hasil koefisien perpindahan panas seluruhnya sebesar 1700,27 W/m2K dengan nilai koreksi sebesar 0,8016 %. nilai pressure drop pada shell sebesar 2,57 Bar dan pada tube sebesar 1,47 Bar.
=========================================================
Cooling Water Heat Exchanger (CWHE) is a tool that has the function of cooling water fluid (Water Demin) which has a high temperature due to passing through the lubrication system on bearings and gas turbine components. In this research, we will design a shell and tube type cooling water heat exchanger that has high performance values and low pressure drop values.
The stages in this research include four parts, namely: First, determining initial design assumptions regarding the shape and size of the shell and tube based on TEMA (Tubular Exchanger Manufacturers Association) standards and existing conditions. Second, calculating the shell and tube type Heat Exchanger design analytically. , Third, correct the analytical design using an iterative method using Microsoft Excel until the value approaches < 5% and finally calculate using HTRI software.
The performance of the Shell and Tube type cooling water heat exchanger obtained a value of 65.307%, the heat transfer rate was 10000000 W. The results of the design and dimensions using TEMA (Tubular Exchanger Manufacturers Association) standards include a tube diameter of 1 in (BWG 14), the number of tubes is 2156 pieces, shell diameter of 1.568 m, baffle spacing of 0.6375 m, number of baffles 16 pieces, total heat transfer coefficient of 1686.645 W/m2K with a correction value of 0.7918%. Meanwhile, based on numerical calculations using HTRI Design and Rating software, the overall heat transfer coefficient was 1700.27 W/m2K with a correction value of 0.8016%. The pressure drop value on the shell is 2.57 Bar and on the tube is 1.47 Bar.
