Complete combustion in a furnace must be achieved to reduce the emissions. In order to achieve the same, this work focuses on the optimization of performance parameters of centrifugal blower for complete combustion in the furnace with the aid of one the optimization techniques, i.e., Taguchi-based grey relational analysis. The type of blade and percentage of the opening of the blower duct is selected as input parametric characteristics. For experimental design, tests are planned based on Taguchi’s L12 orthogonal array and by conducting experiments as design, the output process parameters i.e. velocity, discharge, input power, output power, and mechanical efficiency are calculated and found the operating settings of the blower by manipulating grey relational grade with Taguchi optimization technique. The test results propose that the type of blade has the most noteworthy impact on the multiple performance qualities rather than the percentage of the opening of duct and blower with a backward blade and 50% opening of duct shows the best-operating conditions.
