Flexible control

The latest FD-C (GA) packaged oven burner from Lanemark International provides flexible, high turn-down control of both gas and air and uses the latest 'air pressure lead' (APL) monobloc gas valve technology.

The concept allows changes in process heat demand to be transmitted to the burner by a modulating control signal which enables the speed of the burner combustion air fan to be varied, with the burner windbox differential air pressure increased or decreased accordingly.

These pressure changes are then transmitted to the master gas control valve, which simultaneously adjusts the gas flow rate to maintain a safe, efficient gas/air ratio at all times.
