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.

Each boiler must have a minimum efficiency of 86% for gas and 85% for oil. The replacement of a gas boiler will probably have to be a condensing boiler unless there is sufficient reason why one cannot be installed. An assessment is carried out by a registered installer on the type of boiler

Condensing vs. Non-Condensing Boilers: What's the

Condensing boilers have a lower return water temperature of 110 degrees, making them more efficient than non-condensing boilers. These systems also maintain their high efficiency throughout the changing seasons. The drawback of condensing boilers is that they currently have a limited heating capacity.

Notes on Steam condenser - ME Mechanical

Mar 21, 2016 · Steam condenser is an equipment in which the exhaust steam from the steam turbine is condensed by means of coolant (water).. Thermal efficiency of a closed cycle power developing system using steam as working fluid and working on carnot thermodynamic cycle is given by an expression (T 1 T 2)/T 1.This expression of efficiency shows that the thermal efficiency increases with an increase in

A partial condenser functions as an equilibrium separation stage, so columns with a partial condenser effectively have an extra ideal stage. The "reflux ratio" is an important parameter in column operation. It is normally defined as the ratio of reflux to distillate (L/D), although other formulations (L/L+D, etc.) are occasionally used.
