PENGARUH BAFFLE SPACING TERHADAP EFEKTIVITAS PENUKAR PANAS SHELL AND TUBE JENIS ORIENTATION TRIPLE-SEGMENTAL BAFFLE

Abstract

The utilization of shell and tube heat exchangers is currently increasingly widespread, especially in the fields of industry and technology. Many studies have been conducted to improve the efficiency of shell and tube type heat exchangers so that the production process can run optimally, the important component of shell and tube that most dominantly affects the effectiveness value is the baffle component. A good heat exchanger design is absolutely necessary in order to provide maximum heat transfer effectiveness, one of which is the arrangement of baffle distances. The purpose of this research is to determine the effect of baffle spacing on the effectiveness and pressure drop in shell and tube type heat exchangers using a triple-segmental type baffle. The object of this experimental research is a triple-segmental shell and tube heat exchanger with variations in baffle spacing, where the placement of baffles is carried out with a variety of distances including 50 mm, 80 mm, and 100 mm. The data collection process starts from the input of cold water fluid in the shell (Tcin) temperature of 30 ° C with a water discharge of 6 lpm and hot water fluid input in the tube (Thout) temperature of 80 ° C with a discharge of 4 lpm, the two fluids enter the shell tube so that the heat exchange process occurs, then taking data on the dingan fluid temperature out (Tcout), hot fluid out (Thout), and hot water pressure in (Pin) and out (Pout). The data obtained is then analyzed descriptively, namely taking data from measuring instruments, the results of the measurements are entered in the table, and displayed in graphical form. The temperature and pressure values are the initial data for calculating the effectiveness and pressure drop values.
