Numerical and experimental investigations to lower environmental impact of an open fireplace
چکیده انگلیسی

Experimental and computational activities were performed to determine the possible improvements of total environmental impact of a wood-open fireplace. Two models of fireplaces will be discussed, both with the same power and with only a difference relative to the geometry of the internal elements of the heat exchanger. In the second model the two blades have been substituted with one pipe that represents a possible and cheaper solution in the way of optimization. The optimization process has been conducted up to the determination of a third configuration with a better thermal efficiency. While combustion emissions are difficult to reduce where only a minimum control of actual combustion conditions can be ensured in such domestic appliances, a significant improvement can be considered for the heat recover efficiency. This improvement can be achieved through a detailed analysis of the thermal conditions realized and can require modifications to the heat exchanger geometry profitable from the manufacturing point of view too.
