Ash removal into an ash container

Complete screw conveyor ash removal from the ash chamber into
an external, mobile, zinc-plated ash container. The level in the ash
trough is monitored with a light barrier. If a certain level is exceeded,
a specific amount of ash is conveyed into the container. In this way,
the ash can cool down in the ash chamber under the combustion
system. In standard mode, only cooled ash is fed into the container.
For cleaning purposes, ash removal can be switched to continuous
operation in the event of a boiler standstill.
Standard delivery:
■ Boiler ash pan made from heat-resistant steel
■ Combustion chamber screw conveyor made from heat-resistant
steel
■ Steeply inclined screw conveyor as a pipe conveyor with direct
transfer from the ash removal screw conveyor
Drive via geared screw conveyor motor
