Modelling the performance of condensing boilers
24/3/2021 · This means that the boiler efficiency rate can reach up to 90-91% at full condensation (80% from fuel burning and 11% from steam condensation). In a condensing boiler high-performing heat exchanger, the released gases are cooled to a temperature level that is almost equal to the water temperature from the reverse loop.

Evaluation of retrofitting a conventional natural gas fired …
1/12/2004 · The performance of condensing boilers was examined with water flow and return temperatures of 60 and 40 C, respectively, in addition to the 80 and 60 C used for a non-condensing unit. The results from the field study confirmed that substantially greater annual efficiencies were obtained with condensing boilers than with traditional boilers.
