HEAT RECOVERY PACKAGES
FRECO - FLASH STEAM HEAT RECOVERY UNIT
The Adcatherm Freco – is a skid mounted package unit to facilitate heat recovery from flash steam, condensate or both.
The Freco is specially recommended for heating a continuous flow of fluid, such as make-up water to a boiler feed water system.
Non-continuous flow applications may require additional recirculation, relief valves, or other devices, to avoid system damage due to overheating and consequent overpressure.
It is known that the condensate return and its recovery is beneficial and ensures a remarkable energetic efficiency. However, the condensate, which is initially at high temperatures, ends up expanding and losing most of its energy through the formation of flash steam. On the other hand, feed water temperatures higher than 90ºC to the boiler feed pumps when coming from atmospheric vessels will normally cause cavitation on the pumps with all
the consequent damages.
The Freco system prevents this problem since it is installed downstream of the pumps, using the high pressures which can be found there, allowing the condensate heating above 100ºC, without the existence of any boiling, & naturally eliminating the chances of cavitation.
Different types of materials and designs available, according to the application.
Atmospherically vented units, to avoid extra back pressure in the condensate return system.
Steam, water, hot condensate and other fluids
compatible with the construction.
