Kiln structure<br />
Walls<br />
The <strong>kiln</strong> may have double-skin or triple-skin walls depending on <strong>kiln</strong> width and tem<strong>per</strong>ature<br />
so as to provide an effective barrier even in the event of lengthy downtimes caused<br />
by power failures.<br />
Refractory brick characteristics vary so as to prevent any alkaline aggression and<br />
respond correctly to the different tem<strong>per</strong>atures.<br />
Wall insulation consists of rigid layers fitted with staggered joints: consequently all the<br />
wall insulation is dry and does not require any preheating.<br />
A high-efficiency double sealing chicane that allows the <strong>kiln</strong> to o<strong>per</strong>ate at high pressures<br />
is also featured.<br />
The weight of the roof rests on the walls, thus making the entire structure highly stable:<br />
lifting of the walls - caused by thermal expansion of the refractory bricks - does<br />
not cause any problems at all because the roof is not bound to any other structure<br />
and is thus free to move upwards, continuing to rest on the walls as it does so.
