Published: April 2023

Boiler mempunyai peranan berarti pada PLTU di indonesia. Pipa Boiler mengalami kegagalan beroperasi yang diakibatkan kebocoran pada tube Secondary Superheater - out. Penelitian ini bertujuan untuk memahami mekanisme serta penyebab terjadinya kebocoran tube agar diperoleh solusi yang tepat, sehingga PLTU dapat beroperasi kembali dengan baik. Material pipa yang mengalami kegagalan ini adalah jenis ASTM SA 213 T91. Secondary Superheater mengalami kerusakan berupa pecah dan memiliki bibir tipis (thin lip rupture). Penipisan yang terjadi pada area rupture mengindikasikan bahwa tube mengalami short term overheating yang diawali dengan bulging/swelling. Short term overheating akan dibuktikan dengan analisa struktur mikro dan hasil pengujian kekerasan. Pengamatan visual pada area bocor tidak memperlihatkan adanya deposit yang menempel pada dinding bagian dalam tube, namun ditemukan serbuk deposit di dalam dinding tube yang terbawa aliran steam. Beberapa investigasi yang dilakukan terdiri dari inspeksi visual, kekerasan vickers, analisis struktur mikro, uji XRD. Dapat disimpulkan kegagalan terjadi karena terganggunya aliran steam akibat serbuk deposit menumpuk di daerah elbow dan bukan karena lapisan oksida yang menempel di dinding dalam pipa.

Histological evaluation of tissue-engineered products, including hydrogels for cellular encapsulation, is a critical and invaluable tool for assessing the product across multiple stages of its lifecycle from manufacture to implantation. However, many tissue-engineered products are comprised of polymers and hydrogels which are not optimized for use with conventional methods of tissue fixation and histological processing. Routine histology utilizes a combination of chemical fixatives, such as formaldehyde, and solvents such as xylene which have been optimized for use with native biological tissues due to their high protein and lipid content. Previous work has highlighted the challenges associated with processing hydrogels for routine histology due to their high water content and lack of diverse chemical moieties amenable for tissue fixation with traditional fixatives. Thus, hydrogel-based tissue engineering products are prone to histological artifacts during their validation which can lead to challenges in correctly interpreting results. In addition, chemicals used in conventional histological approaches are associated with significant health and environmental concerns due to their toxicity and there is thus an urgent need to identify suitable replacements. Here we use a multifactorial design of experiments approach to identify processing parameters capable of preserving cell-biomaterial interactions in a prototypical hydrogel system: ionically crosslinked calcium alginate. We identify a formalin free fixative which better retains cell-biomaterial interactions and calcium alginate hydrogel integrity as compared to the state-of-the-art formalin-based approaches. In addition, we demonstrate that this approach is compatible with a diversity of manufacturing techniques used to fabricate calcium alginate-based scaffolds for tissue engineering and cell therapy, including histological evaluation of cellular encapsulation in 3D tubes and thin tissue engineering scaffolds (∼50 μm). Furthermore, we show that formalin-free fixation can be used to retain cell-biomaterial interactions and hydrogel architecture in hybrid alginate-gelatin based scaffolds for use with histology and scanning electron microscopy. Taken together, these findings are a significant step forward towards improving histological evaluation of ionically crosslinked calcium alginate hydrogels and help make their validation less toxic, thus more environmentally friendly and sustainable.
