Abstract

Pressure Wave Generator (PWG) yang akan digunakan untuk membersihkan slag pada panel superheater menimbulkan beban impuls yang berpotensi menghasilkan tegangan tinggi dan defleksi pada struktur. Maka dari itu, dilakukanlah penelitian yang bertujuan mengevaluasi respons panel superheater terhadap beban impuls PWG. Simulasi dilakukan secara sekuensial atau berurutan dengan memindahkan data beban tekanan dari Fluent ke solver struktural untuk menghitung deformasi dan tegangan secara terpisah.atau berurutan setelah fluent menghitung beban. Validasi struktur dilakukan dengan membandingkan hasil simulasi terhadap batas tegangan izin material dan defleksi yang dibandingkan dengan standar ASME section I part D serta API 530. Didapatkan hasil bahwa tekanan 600 bar menghasilkan tegangan ekivalen maksimal 2,7 MPa dan defleksi 0,13 mm. Tekanan 400 bar menghasilkan tegangan ekivalen maksimal 1,7 MPa dan defleksi 0,09 mm. Tegangan dan defleksi kedua variasi tekanan tersebut masih di bawah batas tegangan izin material dan di bawah batas defleksi sehingga dapat disimpulkan bahwa 600 bar dan 400 bar aman untuk panel superheater.

The Pressure Wave Generator (PWG) used for slag removal on superheater panels generates impulse loads that can cause high stress and deflection. Therefore, this study evaluates the structural response of a superheater panel subjected to PWG impulse loading. Sequential simulations were performed by mapping pressure load data from Fluent to a structural solver to compute deformation and stress independently. Structural validation was conducted by comparing the simulation results against allowable material stress limits and deflection criteria from ASME Section I part D and API 530 standards. The results indicate that a pressure of 600 bar produces a maximum equivalent stress of 2.7 MPa and a deflection of 0.13 mm, while a pressure of 400 bar results in a maximum equivalent stress of 1.7 MPa and a deflection of 0.09 mm. Since the stress and deflection for both pressure variations remain well below the allowable limits, it is concluded that operating pressures of 400 bar and 600 bar are safe for the superheater panel.
