Indeed, the heat exchanger is capable of cooling the fumes which are saturated with steam and which condense into water in the liquid state, using the water from the heating system at low temperature (approx. 50°) circulating through it.

Boilers | Why return condensate to the - Plant Services

Apr 21, 2010 · Steam contains two types of energy: latent and sensible. When steam is supplied to a process application (heat exchanger, coil, tracer, etc.) the steam vapor releases the latent energy to the process fluid and condenses to a liquid condensate. The condensate retains the sensible energy the steam had.

Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted. This condensed vapour leaves the system in liquid form, via a drain.
