2.3.4 Ventilation System
Place a ventilation duct with a hood above the atomizer.
(1) The hood, duct and ventilation fans used should be all made of metal. Those made of plastic are
inappropriate as they are softened by heat.
(2) A cooling-fan air capacity of about 600 to 1200 m
3
/h is appropriate. Too much suction force will cause the
flame to flicker as well as create excessive noise. Placement of a damper in the duct system is ideal for
setting the optimum air flow.
