Özet
Boiler is a pressure vessel that provides a heat transfer surface (generally a set of tubes) between the combustion products and the water. A boiler is usually integrated into a system with many components. It used to produce steam. The generation part of a steam system uses a boiler to add energy to a feedwater supply to generate steam. The energy is released from the combustion of fossil fuels or from process waste heat The purpose of this study is to examine and evaluate the positive effects of using cast iron and stainless steel in steam boilers, specifically with regard to improving the boilers' thermal and structural performance, mechanical qualities, and durability. Numerical analysis, 3D mathematical modeling, and simulation were crucial to the success of the investigation. The study found that the maximum Von Mises stress recorded for the cast iron was 2.0499 MPa, and the maximum Von Mises stress of the stainless steel was 2.0406 MPa, both based on simulations and numerical results produced via the ANSYS software package. Cast iron had a maximum elastic strain of 0.0328. In contrast, stainless steel's maximum elastic strain was only 0.0140. Cast iron experienced maximum overall deformations of 82.86 mm. As a point of contrast, the maximum overall deformations of the stainless steel were just 36.66 mm. Stainless steel's mechanical qualities surpass those of cast iron. Stainless steel's superior corrosion resistance, durability, and mechanical performance meant it was the material of choice for the steam boiler. The Von Mises stress, elastic strain, and total deformations were all reduced by 4.53%, 57.32%, and 55.71%, respectively, when stainless steel was used in place of cast iron in the second case study scenario. © 2024 American Institute of Physics Inc..
