Case Study
The problem :
Our customer had a 6 bars steam system on his site, aimed to feed
various production processes. The water return process is made
through a condensate system. These condensates are stocked
in a tank and have a temperature about 98°C to 100°C. 7% of
the condensate return throughput is evaporated and released in
the atmosphere via an insulated stainless steal 300mm diameter
duct located on the tank. The customer desired to use this energy
instead of losing it.
Spirax Sarco Solution :
To create a heat exchange solution to heat the secondary fluid
thanks to the energy recovered from flash steam. The EVC solution
allows to heat and maintain the water temperature around 78°C
which is currently heated electrically.
Results :
Energy recovered (steam)
300 kg/h
Secondary fluid heated and
maintained at
78°C
Condensate throughput
8 000 kg/h
Energy recovered
187,5 kW
Energy recovered value
63 000 € per year
Payback period
Less than 12 months
The Spirax Sarco EVC solution uses a feed tank flash
steam to heat a secondary fluid and allows a customer
to recover 63 000€ of energy per year
