effectiveness of boiler exhaust gas – Steam Boiler In …

Condensing boiler – Wikipedia. 2019-3-27 · 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
