The following should be checked for further energy-saving and energy-reclaim opportunities: the heating needs and energy efficiency aspects of heat-consuming processes, products and equipment; and; the heat distribution systems (such as steam and condensate). Heat and energy losses in a boiler system can be reduced in several ways.

The potential for energy saving depends on the type of boiler installed and the fuel used. For a typically older model shell boiler, with a flue gas exit temperature of 260 o C, an economizer could be used to reduce it to 200 o C, increasing the feed water temperature by 15 o C. Increase in overall thermal efficiency would be in the order of 3%.
