Circumferential Joints, Boiler Shells, Double Strap Butt Joints


Manufacturing & production engineering is mostly concerned with heavy machinery which is a must for mass production. One such component is a boiler which is used in power plants for steam production. For steam production Water is boiled inside boiler assembly with the help of combustion of fuel in furnace. The water in liquid state is made to pass through pipes which come in contact with of heat being generated in the furnace. This heat increases the temperature of water above its boiling point and ultimately the water is converted into steam. This steam is stored inside boiler shell which is developed with the help of lap joints & butt joints. Boiler shell comprises a longitudinal joint which is a double strap double riveted butt joint. In this dissertation work Static structural analysis of this boiler joint will be performed mathematically & with the help of ANSYS simulation. The results of both will be compared in order to validate the simulation. Once the validation is completed, then some new materials will be tried in place of conventional low carbon steel. This way the boiler joint will be optimized. Mathematical analysis will be completed with the help of literature already available in machine design of mechanical engineering. Conventional material which will be used is low carbon steel (mild steel). ANSYS simulation will be performed using aluminium alloy, Asbestos, Carbon Fibre, Inconel materials and Epoxy Carbon. The results obtained through simulation will be then compared with the results obtained through mathematical calculations. In order to complete the simulation work, model of double strap double riveted butt joint will be developed in CATIA V5-6 R2017 & then this model will be exported to ANSYS. The Analysis part will be completed in ANSYS 19.2.
