The CE mark, or formerly EC mark, is a mandatory conformity marking for certain products sold within the European Economic Area (EEA) since 1985. The CE marking is also found on products sold outside the EEA that are manufactured in, or designed to be sold in, the EEA.
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.
Blowdown Separators. Wilson boiler blowdown systems are built around the Wilson centrifugal blowdown separator. The boiler blowoff is piped. tangentially into the separator. In the resulting vortex the pressure is released, allowing the steam flash to rise through the vent. while the water and sludge fall through the drain.
