Condensation gas boiler: principle of operation, pros and …

A condensing boiler produces a constant flow of condensate which drains into your household's waste water just like your sink and washing machine. For safety, if the outlet becomes blocked your condensing boiler will automatically stop. The most common cause for this is a frozen boiler condensate pipe.

Condensing Boilers Evaluation: Retrofit and New Construction …

31/10/2016 · The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of …

Condensing Boilers and Low-Temperature Baseboard Convection

Among the main elements of the condensing gas heating boiler should be noted: A device that is designed to collect the condensing liquid, which receives the coolant after cooling exhaust air masses. Thus, steam is condensed and gives off thermal energy to water.Then the condensate is discharged into a special container through the drain device.

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., which would otherwise have been wasted.

Heat and mass transfer characteristics of simulated …

27/7/2004 · The exit flue gas temperature of a conventional boiler is usually higher than 150 C, sometimes as high as 200 C, to avoid low temperature corrosion. At such temperatures, the water vapor entrained in the flue gases does not condense and the latent heat cannot be reclaimed, which leads to a considerable heat loss.
