research on energy saving of flue gas condenser in gas boiler

MAXIMUM ENERGY GAIN FROM FLUE GASES

Our flue gas ercs condensation plants recover up to 50 % of the boiler output from thermal energy in heat contained in otherwise unused flue gas. The latent heat of the evaporation or condensation heat is recovered by condensing flue gas. In addition, one part of the sensible heat can be extracted by means of a decrease in tem-

How to improve the energy efficiency of boiler systems

Jan 08, 2016 · The condensing boiler may never operate as intended, in the condensing mode, thus limiting it's energy saving potential. For example, applications such as fan coils, finned tube baseboards, cast iron baseboards and cast iron radiators are designed around 180 degree F supply temperature and 160 degree F return water temperature and therefore

Condensing boiler - Wikipedia

Efficiency. Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.
