Burner lance
Definition
Assembly that carries the atomizer into the combustion chamber and actuates the needle shut-off; certified as a safety shut-off device.
The burner lance carries the atomizer from the burner housing into the combustion chamber and contains the mechanism that actuates the shut-off needle. In most industrial oil burners the lance, not the nozzle, is the part that has to close the fuel supply safely when the burner stops.
Fluid Control Instruments Ltd builds the lance in three actuation systems. Type H is actuated hydraulically by the fuel pressure itself and needs no external valves; type EH is also hydraulic but carries an integrated solenoid valve; type HA is pneumatic and is used where the burner has an air supply. All three are available with or without an integrated volume regulator and with or without an electrical pre-heater.
Combined with original Fluid Control Instruments Ltd atomizers or atomizer parts, all three types are certified safety shut-off devices for combustion plants according to DIN EN ISO 23553-1:2022.
