Type of Technology
/Equipment
Hot Disc PyroRotor Prepol - SC
(Step combustor)
- Transport principle
is unsuitable for
burning difficult fu-
els. No active mixing
of air & fresh fuel
surface. - Mechanical parts for
fuel transport are
directly in contact
with hot and chemi-
cal aggressivegases.
Also the disc is an
integral part of the
system and needs to
run continuous. - Less flexibility of the
Hot Disc and risk
of blockages with
increasing pressure
drop and reduction
of AF throughput. - Due to its design
and placement
location in pre-
heater its capacity
has a limitation in
case of higher TSR
substitution.- Increase of un-nec-
essary air to the
kiln system. Block-
ages of air nozzles
by melting fuels
and slags. - Meal will
„ extinguish
“the combustion
reaction. Fuel is
covered by meal.
A lot of unburned
will drop into the
calciner. - High consumption
of “expensive
“pressurizedair.
A lot of additional
leakage air to the
process with dis-
advantages in heat
balance and there-
fore on clinker pro-
duction rate. Fre-
quent blocking of
nozzles (arranged
on the floor)
resulting in
additional
maintenance work
(cost factor!)
- Increase of un-nec-
