1. BURNER DESCRIPTION
Two stage gas oil burner with blue flame and, therefore with low pollutant emissions (Nitric Oxide NOx,
Carbon monoxide CO and unburnt Hydrocarbons).
The dimension of the boiler's combustion chamber must respond to specific
values, in order to guarantee a combustion with the lowest polluting
emissions rate.
The RIELLO Technical Service Personnel will be glad to give
you all the imformation for a correct matching of this
burner to the boiler.
