5.4 Accessories, ash removal
External container
Complete screw conveyor ash removal from the ash chamber of the
combustion block into an external, mobile and zinc-plated ash con-
tainer (standard 240 litres). The light barrier control unit keeps the ash
level via the screw conveyor constant. In this way, the ash can transfer
all its heat in the ash trough under the combustion system and only
cooled ash is fed into the container in normal operation.
Standard delivery:
■ Boiler ash trough with ash level control and ash removal screw con-
veyor made from heat-resistant steel
Driven via geared screw conveyor motor
■ Ascending ash screw conveyor as a pipe screw conveyor with direct
transfer from the ash removal screw conveyor

■ Infrared light barrier for level monitoring of ash in combustion cham-
ber
Standard versions (A-D also possible reversed)
Connection station with mobile ash container can also be installed
rotated 90°. It is possible to select the direction in which the ash con-
tainer is pulled out.
