Waste heat recovery - OPTIMUM Environmental and Energy

Often waste heat recovery cannot be realized as a consequence of fouling or heavy dust loads in flue gases. Waste heat then remains what it is: waste heat, to be discharged through the chimney. OPTIMUM developed a system for the line in cleaning of tubes in heat exchangers, combined with a specially designed heat exchanger or boiler.

Recover Heat from Boiler Blowdown - Department of Energy

Recover Heat from Boiler Blowdown. Heat can be recovered from boiler blowdown by using a heat exchanger to preheat boiler makeup water. Any boiler with continuous blowdown exceeding 5% of the steam rate is a good candidate for the introduction of blowdown waste heat recovery. Larger energy savings occur with high-pressure boilers.

HEAT RECOVERY BOILERS - Thermopedia

The convective elements of boilers fired by municipal industrial or other waste materials are often referred to as heat recovery boilers although, apart from their geometry, they are more akin to the rear end of a furnace-fired boiler. Perhaps the most common heat recovery boiler is now the gas turbine heat recovery boiler.
