1.0 GENERAL FEATURES
These burners are designed to be installed into boilers provided with very big combustion chamber but the tube nest very close to the
burner stokhole. The flame produced by this burner series is very short, but has the energy necessary to take up all the combustion
chamber and then exchange this energy to the water, as to get very high efficiency. The construction and test of these burners are per-
formed both in laboratories and directly on site, observing the peculiarities of these boilers: the need to operate in slight depression and
to heat the boiler in low flame for a long time before exploiting the highest performance. The flame is divided into smaller flames perfor-
ming the same output but distributing the energy uniformly without stressing the boiler structure. To complete this product range, the
flame modulation is performed by a modulator with pressure probe connected to. These burners can be provided for all kinds of fuels
and can be designed according to the customer requests. They are provided with all the safety requirements according to the Stan-
dards in force These burners can be installed in the newest microprocessor-controlled systems.
