A Novel Modelling Approach for Condensing Boilers …

2015-12-31 · Condensing boilers use waste heat from flue gases to pre-heat cold water entering the boiler. Flue gases are condensed into liquid form, thus recovering their latent heat of vaporization, which results in as much as 10%–12% increase in efficiency. Modeling these heat transfer phenomena is crucial to control this equipment. Despite the many approaches to the condensing boiler modeling, the

Investigating the effects of heat exchanger on flame

In compact condensing boilers the distance between the burner and heat exchanger is small enough to cause intense interactions. That is why we constructed a simplified CFD model of a boiler to study various cases with different distances between the burner and heat exchanger.
