4.8 Air setting
Set the operations switch (S1) on the on position (I). Loosen the screw (E)
that locks the air adjustment knob. Adjust the position of the air damper
using the wheel until the desired air flow is achieved. Clockwise adjustment
reduces the amount of air, whilst an anticlockwise adjustment increases
the air flow. After adjustment, lock the damper position using the screw (E).
Damper position can be read on the damper scale (F). Check the air settings
by conducting a flue gas analysis.
4.9 Nozzle assembly adjustment, brake
plate
The nozzle assembly control is used to achieve the most favourable pressure
drop across the brake plate as possible at the various effect stages. The
nozzle assembly is adjusted manually (B) in order to obtain the optimum
pressure drop for good combustion.
