Fuel discharge

Weld base, pushrod drive, twin

For part no., see pricelist
The weld base is for securing the pushrod drive. The solid steel
structure has been structurally tested. It permanently withstands the
dynamic stress. This is conditional on the structure being embedded
in concrete as prescribed.
Standard delivery:
■ 1 weld base per pushrod drive

Bunker weld base (fuel store)

For part no., see pricelist
The steel sections are used for welding the pushrod guide elements
and the trough of the push floor screw conveyor. The weld base in
the fuel store is also the slide rail for the pushrod.
Standard delivery:
■ UNP 240 rolled profiles with anchoring irons per pushrod over the
entire length
■ 50/50/5 angle profiles with anchoring irons over the entire width of
the push floor for the push floor screw conveyor
To be carried out by the customer:
■ Production of the concrete floor
■ Installation of the profiles level with the concrete floor (max. devia-
tion of 5 mm over 10 m)

Hydraulic unit, AS single

For part no., see pricelist
Hydraulic unit for actuating single pushrod drives with discharge
function. When the required fill level of the push floor screw con-
veyor is reached, the discharge function switches off.

Article price per m
Total price is calculated as follows:
For pushrod drive, single: (Pushrod drives in pce x length of fuel
store in m) + (1 x width of fuel store in m) x article price
For pushrod drive, twin: (Pushrod drives in pce x length of fuel store
in m) + (2 x width of fuel store in m) x article price
■ Switching:
By boiler control unit, protected by temperature and level switches
