Condensing boiler - WikiMili, The Free Encyclopedia

2019-10-16 · 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.

2019-7-29 · Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by using waste heat in flue gases to pre-heat cold water entering the boiler.Water vapour produced during combustion is condensed into liquid form, which leaves the system via a drain.

novel flue gas heat recovery system based on low

Abstract. Flue gas from natural gas boilers contains much water vapor, so the latent heat occupies a large proportion of the total waste heat. This paper introduces a flue gas driven absorption system based on low-pressure regeneration liquid cycle to recover water and waste heat, especially the latent heat.

In a conventional boiler, the flue gas temperature is kept above the flue gas dew-point (roughly 140 F) to prevent the water vapor from condensing in the boiler or exhaust stack and avoid corrosion of of cast-iron, steel, or copper components. Water vapor contains a significant amount of latent heat energy—roughly 1000 Btu per pound of water.
