GENERAL FEATURES

This particular burner series has been studied to use compressed air or alternatively steam, to atomize heavy oil. In this way we have
achieved higher efficiency compared to mechanical atomization. These burners are equipped with a low pressure nozzle which permits
to save fuel and, above all, to preserve the whole system. All burners are progressive type, complete with electrical panel, with self cle-
aning nozzle system and oil pump motor to be separately installed by the final user. A supplying system of compressed air and steam
at 8 bar must be provided on the site. All burners are ignited by means of a pilot flame burning LPG or Natural gas. The standard ver-
sion of the burner uses compressed air to atomize oil fuel. If compressed air is not available on site, it is possible to use steam to ato-
mise oil fuel by using a special kit. In any case compressed air is essential: to ignite the burner when steam is not available, to control
valves and for self cleaning nozzle.
