Description

Exergetic analysis of a typical hot-water condensing boiler (HWCB) was carried out using the general equation for hot-water/steam boilers. Good correlation with results reported in the literature was found. Significant discrepancy between condensing boiler exergetic efficiency and energetic efficiency is demonstrated. The same method is applied to estimate theoretical exergetic efficiency of a proposed vapor vacuum heating and condensing boiler (VVHCB) combo. Comparative calculation for a Boston area house heated by a condensing boiler indicated potential savings of 43.8% energy/fuel for the VVHCB alternative.
