Abstract

A device for the reliable measurement and control of the filling level in the quencher sump of a quenching chamber arranged downstream of the gasifying chamber is provided. The device has a differential-pressure transmitter. The measuring location recording the pressure of the gas chamber is flushed with inert gas. The device unproblematically senses the pressures in the quenching chamber and at the bottom of the quencher sump. The difference between which is used as a controlled variable for the filling level.
