The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.
Waste Heat Recovery. With the high cost and environmental impact of fossil fuels, heat energy is a precious commodity that cannot be wasted. Any exhaust gas stream with temperatures above 250°F has the potential for significant waste heat recovery. Consumers of waste heat energy can be found in almost any facility and are easy to locate.

The installation of a boiler economizer helps to solve this problem. An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost.
Heat recovery using heat exchangers. Heat recovery from residual blowdown. About 40% of the energy in boiler blowdown can be recovered through the use of a flash vessel and associated equipment; however, there is scope for further heat recovery from the residual blowdown itself.
