Abstract

This present work is aimed to optimize the machining parameters and study the effect of powder mixed dielectric fluid on EDM process. TOPSIS method of optimization is adopted to identify the optimal machining parameters. HCHCr die steel is preferred as machining material. Ni, Zr and Ni+Zr were selected as powder inclusion in dielectric fluid due to hard and ductile nature. L9 array Taguchi DOE is preferred to perform the experiments with parameters like peak off time, pulse off time and pulse current. TOPSIS study revealed that, third level of powder dielectric fluid (Ni+Zr), 7A peak current, 9 μs pulse on time and 2 μs pulse off time were specified as optimal condition. Pulse on time (Ton) was having high impact on MRR and Ra while performing machining operation on HCHCr die steel. SEM analysis was done to find the effect of powder mixed dielectric fluid while EDAX analysis was done to ensure the presence of powder inclusion.

Abstract

The boiler efficiency is improved with the help of economizer it is one of the main accessory part in the boiler. Boiler feed water is preheated with the entry of reused flue gas through economizer. This present work is planned to analyze the overall heat flux and overall heat transfer in the boiler economizer. Higher amount of flue gases passing around the economizer to preheat the feed water at the same time much more heat is transferred. The heat transfer is analyzed by statistical method with influence of different process parameters. Economizer fin dimensions are major consideration to taken for this analysis and estimate the overall heat flux and overall heat transfer. The process parameters of this study are named as thickness of the fin (3.5 mm, 4 mm, 4.5 mm and 5 mm), Height of the fin (4 mm, 5 mm, 6 mm and 7 mm), Fin gap (12 mm, 14 mm, 16 mm and 18 mm and Tube diameter (44 mm, 46 mm, 48 mm and 50 mm). The response values are finding as overall heat flux and overall heat transfer.
