Abstract
In a method for safely operating a coal gasifier which is indirectly cooled by passing a heat-carrying oil through a cooling jacket of the gasifier, the pressure of the heat-carrying oil is continually measured after having passed through the cooling jacket. If the measured pressure falls below a predetermined pressure, the supply of coal and gasifying agents to the gasifier is interrupted, the passage of heat-carrying oil is interrupted and water or steam is passed through the cooling jacket until the gasifier is safely shutdown.
