721 MILLE Low NOx [kW 1.090 ÷ 10.600] - 1

The new N type MILLE series Low NOx burners Class 3 (< 80 mg/kWh), made in aluminum housing with a backward curved centrifugal impeller is studied and developed to get high performance and efficiency combined with low emissions. In this manner these series can burn the two flues separately. This is possible because these burners are equipped with an independent electric motor for the activation of the oil pump. As a consequence during gas firing, the oil pump motor does not operate and remains off. These burners are equipped with a high performance combustion head, designed to achieve an high irradiating flame when they run on natural gas. Instead, when they run on light oil, they are equipped with a by-pass nozzle which, using a pressure regulator, can reach a modulating ratio of 1:3. Therefore, the burners are provided with an UV photocell to control the flame during the operation. Back-pressure in combustion chamber (mbar) N880X PR-MD...xR N925X PR-MD...xR N1060X PR-MD...xR

To know the minimum gas pressure at gas train, in order to get the gas output, it is necessary to add the boiler back pressure to the value read on the curve.
