MECHANICAL DESIGN AND ANALYSIS OF STEEL STACK BY VARYING ITS HEIGHT WITH CONSTANT DIAMETER
International Research Journal of Engineering and Technology (IRJET)
Chimneys are tall and slender structures which are used to discharge waste/flue gases at higher elevation with sufficient exit velocity such that the gases and suspended solids(ash) are dispersed in to the atmosphere over a defined spread such that their concentration , on reaching the ground is within acceptable limits specified by pollution control regulatory authorities. This project summarizes the analysis and design concepts of chimneys as per Indian codes provisions incorporation was also
... orporation was also made through finite element analysis. Chimney models are designed on the basis of constant diameter with change in height taken into consideration. These models are analyzed by finite element software STAAD Pro, ANSYS, emphasis also placed on effect of geometric limitations on the design aspects in designing chimney. The main objective of this study the design and constructional aspects of steel stack (with particular reference to steel plant) adhering to the guidelines given in internationally accepted standards/codes. Therefore, objective of this study was to take a practical case study and carry out design calculations by using the rules of codes viz., IS: 6533 part 1 and 2, IS: 875 part-3, IS: 1893 part1 and 4. Further to get full insight into the design of the steel stacks a complete 3-D finite element analysis was carried out by using ANSYS software. Results have been summarized and conclusions have been drawn.
