GASIFIER APPARATUS FOR DECREASING VARIATION IN FURNACE PRESSURE

摘要

The present invention relates to a gasifier apparatus which can reduce pressure fluctuation in a reactor by smoothly discharging molten slag and gas. According to an embodiment of the present invention, the gasifier apparatus comprises a reactor gasifying waste fuel. The gasifier apparatus additionally comprises a transfer pipe transferring molten slag and synthesis gas generated in the reactor in a vertically downward direction, and discharging the molten slag and the synthesis gas. The transfer pipe includes: a transfer pipe entrance part connected to a discharge hole of the reactor on an upper part of the transfer pipe; a gas discharge hole and a slag discharge hole discharging the synthesis gas and the molten slag respectively as formed on a lower part of the transfer pipe; and at least one gas flow tube arranged in a row with the transfer pipe where the synthesis gas can flow. As the gas flow tube is extended inside the transfer pipe, the transfer pipe communicates with the gas flow tube.
