Abstract

Boiler yang merupakan penghasil panas dan uap untuk pendukung kerja pada sistem industrial sangatlah penting keberadaannya, karena versatilitas dari kedua produk hasil kerjanya tersebut dapat digunakan untuk penggerak mekanik dan pemanas. Boiler yang bekerja dalam kondisi panas dan tekanan yang ekstrem memerlukan maintenance dan perawatan secara berkala, kedua hal ini dapat didukung dengan memperkirakan umur boiler berdasarkan tekanan yang bekerja didalamnya. Penelitian ini menggunakan von mises stress sebagai metode untuk mengukur seberapa besar stress yang terjadi di dalam boiler secara general, dengan simulasi menggunakan software Finite Element Analysis. Von mises stress yang didapatkan akan dibandingkan dengan yield strength dari jenis material yang digunakan guna menentukan apakah akan terjadi deformasi secara plastis pada dinding boiler. Penelitian ini memvariasikan material dan tekanan yang diberikan pada boiler yang dipertimbangkan berdasarkan datasheet dari boiler, dengan variasi material menggunakan SA 516 Grade 70 dan SA 285 Grade A sedangkan variasi tekanan adalah 11 bar, 14 bar dan 18 bar. Hasilnya menunjukkan von mises stress berubah seiring naiknya tekanan dan untuk variasi 18 bar pada SA 285 terjadi deformasi secara plastis.
================================================================Boilers, which produce heat and steam to support work in industrial systems, are very important, because the versatility of these two work products can be used for mechanical drives and heating. Boilers that work in conditions of extreme heat and pressure require regular maintenance and upkeep. Both of these things can be supported by estimating the life of the boiler based on the pressure working within it. This research uses von Mises stress as a method to measure how much stress occurs in the boiler in general, by simulating using Finite Element Analysis software. The von Mises stress obtained will be compared with the yield strength of the type of material used to determine whether plastic deformation will occur in the boiler walls. This research varies the material and pressure given to the boiler which is considered based on the boiler data sheet, with material variations using SA 516 Grade 70 and SA 285 Grade A while the pressure variations are 11 bar, 14 bar and 18 bars. The results show that the von Mises stress changes as the pressure increases and plastic deformation occurred in variation of 18 bar pressure with SA 285 material.
