ABSTRACT:
A fuel fired burner assembly comprises a fuel supply conduit (2) terminating in a nozzle (1) which extends with annular clearance (8a) into a combustion chamber (7) located within a tunnel (3). The nozzle (1) is provided with radially directed outlet passages (18) which convey the fuel from the conduit (2) to the clearance (8a) where the fuel mixes with air entering the clearance (8a) from passages (15), (16) and (8b). These passages formed between the tunnel body (3), an outer tunnel sleeve (11) and an intermediate sleeve (14) between the body (3) and the sleeve (11). The nozzle (1) is also provided with a through-going aperture (19) which is located between two adjacent fuel ports (18) and which is axially offset from the nozzle axis. Extending through the aperture (19) with annular clearance (20) is an electrically operated flame detection probe (21) whose electrode tip (22) is disposed within the central section (6) of the tunnel (3). The annular clearance (20) permits a residual supply of air to enter the tunnel (3) from the clearance (8b) independently of the clearance (8a). The residual air supply flows around the probe (21) to form a cone of flame which enables an electrical current to be passed through the probe (21) between its tip (22) and the metallic grounded tunnel (3).
