The new H type CINQUECENTO series Low NOx burners Class 3 (< 80 mg/kWh) made in aluminum housing with a backward curved centrifugal impeller have been developed to meet the current and future requests regarding the low emissions of Nx. The innovation of the combustion head allows to achieve substantial improvements in terms of emissions reduction, flame stability and reliability. The perfect mix of air/gas within the combustion head of these burners, guarantees a very uniform flame in all working conditions.

Back-pressure in combustion chamber (mbar) Back-pressure in combustion chamber (mbar) Back-pressure in combustion chamber (mbar) Minimum inlet gas pressure (mbar) Minimum inlet gas pressure (mbar) Minimum inlet gas pressure (mbar) Attention: the graph shows the value of the gas output (kW) against the corresponding pressure without the combustion chamber back pressure. 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.
