OSTI ID:5220774
An automatic arrangement in which the intermittent tapping of liquid molten slag from the hearth of a slagging coal gasifier vessel through a tap orifice into a slag quench chamber is selectively controlled by a system of timers, the differential pressure between the gasifier vessel and the quench chamber being measured and deviations from the expected measurements caused by malfunctions being used to override the timer system until the malfunctions have been corrected.
