Single response optimization method in optimizing the process parameters for fume extraction and dust collection system

In metal melting process, melting fumes are generated and heavy pollution all around. These fumes are statutorily required to be controlled before spreading into the environment. Fumes causes various short terms and long-term health issues like bronchitis, irritation in eyes, lung cancer etc. Dust and fume emission can be controlled by providing various techniques like enclosure plant system, air blower, local and dilution ventilation system, by using capture hoods etc. This research paper presents parametric optimization approach with extraction system with the help of single response data analysis method. Experimental trials are conducted by varying the four parameters up to three levels. In this study, parameters namely volumetric flow rate, velocity of fume, inlet dust concentration and temperature are optimized with considerations of single response of outlet dust concentration. L9 orthogonal array was used to conduct the experimental trials with the range 23934-36000 m3/hr for volumetric flow rate, 1-2.5 m/s for velocity, 1.2-3.8 mg/m3 for inlet dust concentration and temperature varying from 135-165 °C. The single response method shows best convergences with optimum process parameters where the minimum outlet dust concentration results are obtained.
