Process heaters are the largest consumers of energy in most plants. A refinery, on average, burns approximately 2 billion Btu/hr of fuel in fired heaters. The total quantity of fuel burned (heat released) is so high that any improvement will result in significant fuel savings. Although there are many ways to improve heater performance, including better design, operation and maintenance, excess air is the No. 1 contributor to poor heater efficiency and must be addressed. High energy costs and tighter emissions regulations require increased understanding and control of excess air. Any reduction in excess air will raise the efficiency of a heater and reduce total emissions. NOX emissions are
