ABSTRACT:
The invention concerns a method for the operation of gasification plants for pulverized fuels, wherein the pulverized fuel is reacted in a flame reaction with a gasifying agent containing free oxygen, into a combustible gas containing CO and H.sub.2. The task consists in precluding upon malfunctions in the supply of fuel, an oxygen discharge into the cooling and treatment plants, taking into consideration delays in the emergency shut-off systems and the controls for the oxygen supply.
As per invention, a well-flowing additional fuel is stored in a reservoir at a pressure higher than the operating pressure of the gasification reactor. Upon malfunctions in the fuel supply, the additionally stored fuel will be transferred, within a short time, into the reaction chamber of the gasification plant. As additional well-flowing fuel combustible gas, liquid fuel or a pulverized solid fuel, also well-flowing, can be used.
