Steam boilers – efficient systems up to 31.5 t/h

boilers can be equipped with integral or external heat exchangers in order to increase their efficiency. They utilise waste heat, which can be used to preheat freshwater or combustion air, for example. Thermal equipment, from mixing coolers and TDS expanders through to vapour coolers, convert waste heat into usable energy for the system.

Waste Heat Recovery Methods And Technologies - Chemical

Economizers for boilers. An economizer recovers waste heat from fluegases by heating BFW, and hence reduces boiler fuel requirements. Flue-gases are often rejected to the stack at 30 to 70°C higher than the temperature of the generated steam. Generally, boiler efficiency can be increased by ~ 1% for every 22°C reduction in fluegas temperature.
