The efficiency of improvement of the boiler is identified as the main priority of this project. This can be done by studying and suggest the ways to enhance the process control of the steam generating system and its instrumentation. Boiler with the closest specifications recommended is taken as the case study. Therefore, the suggested recommendation can be assumed as have been implemented. The recommendation is assumed to be implemented and efficiency calculations using mathematical programming approach has been done. The first phase of the project is the study on boiler in terms fuel characteristics, firing system and combustion control to enhance the efficiency calculation at the later stage. The suggestions on ways to improve have led to the installment of Air preheater (APH) unit at a small capacity refinery boiler. Energy savings calculation has been done and resulting output was satisfactory. Therefore, the first phase of the study has been successful. The second phase of the project is the mathematical programming approach to determine the efficiency of the boiler by assuming suggested improvements in fuel combustion has be implemented. The MATLAB program takes into account of the variation in gas constituents in fuel and gives the most accurate heating values and flue gas analysis based on the theoretical combustion. The efficiency of the boiler is determined to be above satisfactory level thus making the second phase of the project a major success.
