ADCATHERM FRECO FLASH STEAM HEAT RECOVER
DESCRIPTION
The Adcatherm Freco – flash steam heat recovery unit – is a skid mounted package unit to facilitate heat recovery
from flash steam, condensate or both.
The Freco is ideally recommended for heating 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 doing to overheating and consequent overpressure.
It is known that the condensate return and its recovery is benefic 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 to allow the heating of the condensate above 100ºC without the existence of any boiling
and naturally placing the cavitation out from the equation.
