Flash Steam Heat Recovery Unit FRECO
The Adcatherm Freco compact flash steam recovery unit is a skid-mounted unit to facilitate the recovery of the energy contained in flash steam and condensate.
The Freco skid is especially recommended for heating a continuous flow of fluid, such as make-up water for boiler feed.
Non-continuous flow applications may require additional recirculation, relief valves or other devices to prevent damage to the system due to overheating and subsequent overpressure.
It is known that condensate return and recovery is beneficial and ensures remarkable 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 inside the condensate collection tank and boiler feed.
On the other hand, feed water temperatures above 90ºC to the boiler feed pumps, when coming from atmospheric tanks, will normally cause cavitation in the pumps with consequent damage.
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 100 ºC, without the existence of any boiling, and naturally eliminating the chances of cavitation.
