3 Description

3.1 Operating principle

3.1.1. Gas/air setting

Air is sucked in by the fan and the gas injected into the venturi attached to the fan inlet. The fan rotation speed modulates and adapts to thermal energy requirements thanks to the temperatures measured by the various sensors. The gas and air are mixed in the venturi, which enables operation at a constant ratio. The noise of the venturi is absorbed by a silencer attached to its inlet. The gas/air mixture is carried to the burner in the top of the exchanger, guided by the premix channel.

3.1.2. Combustion

The burner heats the heating water circulating in the heat exchanger. At a return temperature lower than around 55°C, the flue gases cool down to a temperature lower than the dew point, thus causing the condensation of the water vapour contained in the flue gases in the lower section of the heat exchanger. The heat released during this condensation process (the latent heat or condensing heat) is also transferred to the heating water. The cooled combustion gases are evacuated via the combustion gas outlet flue. The condensation water is evacuated via a siphon.
