Abstract :
[en] Nowadays, condensing technology is widely used in domestic heating. This paper
presents a model that simulates the performance in steady-state regime of a domestic
gas-fired condensing boiler. The model is similar to a conventional boiler model with a
dry heat exchanger at which a wet heat exchanger is added to simulate the heat
recovered by condensation. Experimental parameters are used to simulate the different
components. The model has been applied to a 24 kW gas-fired condensing boiler test
bench available in the laboratory. According to the experimental results (at full load),
the model predicts correctly the thermal efficiency of the boiler. Indeed, calculated
values are in good agreement with measured values.
