FD-C Burners
2Pages

FD-C series burners are particularly suited to direct-fired applications and can be mounted directly on to the wall of a dryer, oven or process air heating duct to operate either in line with or at 90˚ to the process air flow. FD-C series burners produce short flame profiles – so important for industrial oven design. Combustion air and gas is progressively mixed within the internal burner cone assembly, guaranteeing stable combustion over a wide range of oven/dryer process air flows. Burner turn-down is determined by the ratio of the high and low gas firing rates. The maximum turn-down ratio is 40:1. Lanemark FD-C series packaged burners are specifically designed to offer flexible, high turn-down (gas only) control for process air heating applications in convection ovens and dryers. l Textile and fabric dryers machines l Food processing grain dryers FD burners conform with European Standard EN 746 Part 2 as appropriate and are pre-wired and tested prior to despatch. Specifications The standard FD-C burner comprises a burner windbox including a protective burner cowl, combustion air fan, a manual sliding damper fitted between the combustion air fan and the air entry flange on the burner windbox, a compact monobloc valve gas train and gas burner controls mounted in a control box. Standard control items include a burner controller, ignition transformer and differential air pressure switch. Two 3-way air valves perform safety checks on the air pressure switch in both open and closed modes each time the burner fires, allowing the independent operation of the combustion air fan in conjunction with oven/dryer main recirculation fans.
