Performance enhancement of an industrial fire tube boiler

An Industrial boiler is considered as highly energy intensive equipment. The primary objective of this study to identify and quantify the potential losses different sections fire tube its overall performance. Several saving measures such combustion optimization, excess air control, control flue gases temperature effect excessive or uncontrolled steam blow down on performance are also applied. Energy a result measure has been determined well. In present study, some main causes wastages summed up, by using Auditing. From results audit, boiler’s thermal efficiency found be 70.09% 75.7% respectively. It was observed that these can reduced controlling stack temperature, optimized down. There covered utilized preheat feed water. Economic evaluation resulted in annual fuel 6.3 Million PKRs without any investment but only improving working methodologies. As efforts, savings terms cost determined.
