In a small sized furnace manufacturing company, heat exchanger is a fundamental segment. The productivity of the furnace relies on upon the proficiency and adequacy of the heat exchanger. This research uncovers the experimental execution of Six Sigma DMAIC (DefineMeasure-Analyze-Improve-Control) stages to enhance the adequacy of shell and tube heat exchanger and along these lines enhance the quality and productivity of the furnace. The basic goal is to enhance the nature of the furnace through DMAIC stages. In this case study, the define phase assesses the furnace performance, through distinguishing and lessening different multiple operational energy losses to enhance the general proficiency. In measure stage, the present effectiveness of the heat exchange rate for the heat exchanger was measured and found as 0.61. In analysis stage, there as on for the lessening of effectiveness was distinguished as less heat exchange area through cause and effect diagram. In improve stage; the existing design was modified through various alternative solutions such as factors that identify the performance of heat exchanger by conducting brain storming sessions. In this stage, the solution was identified with the introduction of circular fins over the bare tubes to improve the effectiveness in the shell and tube heat exchanger. Therefore, the effectiveness has been raised from 0.61 to 0.664. In control stage, the control techniques were prescribed to manage the upgrades in shell and tube heat exchanger.Cite this Article Akash A Shukla, Dhaval B Patel.
