Abstract

A mathematical model of an instantaneous, condensing, gas-fired hot water boiler is presented and verified by experiments. The model employs empirical heat and mass transfer coefficients in order to calculate convective heat transfer to the baffled, finned-tube heat exchanger. Radiative heat transfer that occurs with the fiber-matrix radiant burner and the coil is determined by the exponential wideband model. It is found that for a wide range of operating conditions the water temperature rise and flue loss can be accurately predicted.
