Waste incineration

Furnace feed shaft

A crane system lifts the waste out of the garbage bunker and transports it to the feed shaft. In the lower area of the shaft, a hydraulic piston moves the waste material to the combustion grate. The combustion control system opti-mizes the cycle time, stroke length and stroke speed of the hydraulic piston. The height and uniform distribution of the waste column in the shaft prevents unwanted air from reaching the fire and ensures a continuous supply of waste material for the combustion process on the grate. For that reason the level in the feed shaft must be monitored and made available to the crane operator.

Level detection with VEGAMIP 61

The level switch VEGAMIP 61 uses a microwave beam to detect the minimum level with several measuring points at the same height in the feed shaft. Every measuring point consists of a transmitter and a receiver mounted opposite each other in the shaft walls. The entire cross-section of the shaft is covered with this arrangement. Due to the noncontact measuring technique, VEGAMIP 61 requires no servicing.
