Optimizing Boiler Performance

A Design of Experiment sub-project was done in a food chemical processing company to optimize the boiler operations. The key issue was inefficient boiler operations leading to high variations and customer rejections in the end product. Project involved conducting a 2 level factorial experiment with factors like slurry feed rate, steam temperature, steam pressure and boiler output temperature. After analyzing the design, operating settings were optimized to get a consistent rate of evaporation, SOPs were updated and staff was trained on maintaining the optimized settings. The project was able to deliver an annual benefit of INR 45 lacs.
