Abstract

Dari waktu ke waktu perkembangan alat penukar kalor selalu mengalami kemajuan yang manamenyesuaikan perkembangan jaman dan kebutuhan. Pemanfaatan gas buang dari hasil pembakarandapat mengurangi emisi yang bisa mempengaruhi lingkungan sekitar karena karena unsur-unsurzat yang terkandung pada gas buang mengandung unsur yang bisa merusak lingkungan.Potensi energi yang terbuang dari motor diesel masih dapat dimanfaatka untuk sebagai prosespengeringan ikan, sehingga dapat meningkatkan efektifitas dan produktifitas dari hasil ikan yangakan dikeringkan. Analisa perancangan alat penukar panas dengan pemanfaatan gas buang motordiesel untuk alat pengering ikan.Adapun panas yang terdapat pada Gas Buang Motor Dieselsebesar 2500C - 3000C.Dimana gas buang yang berasal dari motor diesel tersebut dialirkan ke alat penukar kalor sehinggapanas yang dikeluarkan menuju alat pengering mempunyai temperatur 500C dan kapasitas dari alatpengering sebesar 100kg/9 jam dan Q = 10kW – 20kW , sedangkan laju aliran massanya 0,686kg/s dengan perancangan alat penukar kalor tipe cangkang dan pipa dimana aliran panas gas buangmotor diesel melalui pipa, dan udara melalui shell.

Abstract

In the welding of carbon steel, the cooling time from the highest temperature or peak temperature can be identified, where the cooling rate is generally represented in a welding thermal cycle. Knowledge of the welding thermal cycle greatly facilitates the understanding of the extent of differences in cooling rates at various applied peak temperatures. The thermal cycle curve can be obtained through direct testing methods, namely by measuring the temperature on the welded plate. However, this method requires extensive equipment and a high level of precision. Therefore, the author conducted an experiment to obtain the thermal cycle curve using an alternative method. This method involves heat treatment, in which the cooling process is carried out in free air (normalizing) while varying the peak temperature for each specimen. The specimens used in this study were AISI 1015 low-carbon steel, with dimensions of 100 × 20 × 20 mm for the larger specimens and 50 × 20 × 20 mm for the smaller specimens. The applied peak temperatures were 750°C, 800°C, 900°C, and 1000°C. The experimental results showed that the cooling rate obtained through the heat treatment process was inversely proportional to that of the welding process. Therefore, determining the thermal cycle using the heat treatment process is not recommended.
