Experimental investigation on performance of a condensing

Oct 01, 2018 · Therefore, the temperature of the thermal agent (and, consequently, the flue gas temperature) is maintained higher in the new boiler and the operating regime still is the non-condensing one. Even so, a condensing boiler should offer better performance in an existing heating system than a traditional boiler [26] .

Condensing Temperature - an overview | ScienceDirect Topics

Consequently, the condensing vapor must have a temperature of not less than ∼50 °C, and this sets the lower limit of the column operating pressure. The boiling temperature of the bottoms product increases as the column pressure increases. Typically, medium-pressure steam, which has a temperature of ∼200 °C, is used in the reboiler.

Jeff Howell's Tips for Central Heating

Condensing boilers only really condense properly (thus extracting the waste heat from the flue gases) at a water return temperature of 54C to 56C. This is usually achieved by having a flow temperature (ie the water flowing out of the boiler) of around 70C. As the water flows through the radiators it gives up its heat to the rooms, thus

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.
