Design and Analysis of Boiler Shell with Fastened Joints

With the increase in the development and rise in the growth of population, there is also rise in the power consumption and usage. The development of technology in the area of boilers and pressure vessels have reached a level of technological maturity. However, the increase in the rise of technology also increased the challenges in the design of boilers and pressure vessels. One of the biggest challenges is to design a boiler for high-temperature applications which can withstand major boiler problems like stress corrosive cracking (SCC) and thermal losses due to conduction and convection phenomenon. This paper aims at designing a geometry for boiler shell which can operate at optimal conditions of Ultra-supercritical thermal power plants and analyse the design with advanced alloys like X38CrMoV5-3 alloy and Inconel 625 which can operate at high temperatures and resistive to sulphidation, slagging and corrosion and compare the results with alloy steel which is used in the production of boiler shells currently in the market. Bolted joints are used in the design in order to reduce the SCC on welded joints. The design of boiler shell is carried out in Solidworks Part Design and the analysis of boiler shell is carried out in Solidworks Simulation.
