An arrangement for and a method of gasifying finely divided, particularly solid fuel under increased pressure with a multi-pipe wall having a plurality of pipes arranged to be supplied with a cooling medium, the multi-pipe wall limiting a gas-collecting chamber and also limiting a plurality of recesses which form combustion chambers, wherein each of the recesses having a plurality of parameters including a depth, a width and an angle of inclination of a peripheral wall and being such that at least one of the parameters is changeable

Arrangement for gasifying finely divided particularly solid fuel under

A heat exchanger for cooling solid substance-containing gases comprises a plurality of heat exchanging tubes through which gases flow. An intake nozzle of a trumpet-shaped configuration is coaxially mounted on and connected to the end portion of each heat exchanger tube. A locking device is provided to connect the intake nozzle to the respective tube.

Heat exchanger for cooling solid substance-containing gas

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.
