Process and apparatus for the production of synthesis gas.

摘要

Synthesis gas is produced by partially combusting of a finely divided carbonaceous fuel in a reactor, yielding synthesis gas and molten slag. Slag is removed from the bottom of the reactor. Slag droplets-containing synthesis gas is removed from the top of the reactor and passed upwards through a tube along at least a part of which a coolant is passed. Consequently the synthesis gas is passed downwards through a heat exchanger, from the lower part of which the cooled synthesis gas is removed. An apparatus for the production of synthesis gas comprises a gasification reactor with a slag outlet at the bottom and a gas outlet at the top, a tube running from the gas outlet to a connecting means which connects the tube with a gas inlet at the top of a heat exchanger and an outer pipe surrounding at least a part of said tube for the circulation of a coolant. The heat exchanger has a gas outlet near the bottom.
