Improve Your Boiler's Combustion Efficiency

On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Boilers often operate at excess air levels higher than the optimum.
