cy boiler with an economizer. If a steam boiler does not have an economizer, it can be retrofitted in the field. According to Kenneth McKelvy of Babcock and Wilcox, the rule of thumb is every 40°F (22°C)decrease in stack temperature equates to a 1% increase in boiler effi-ciency. A typical economizer can increase boiler efficiency by 4% to 6%.
