GASIFICATION SYSTEM - CHUGOKU ELECTRIC POWER

Title:

GASIFICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2015/132919

Kind Code:

A1

Abstract:

The purpose of the present invention is to enhance the heat exchange efficiency of a heat exchanger and thus efficiently gasify a raw material for gasification. This gasification system (100) is configured so as to include: a counter flow heat exchanger (30) that is provided with both a low-temperature side flow channel (36) through which a raw material for gasification flows and a high-temperature side flow channel (37) into which a supercritical gasification product stream is introduced and by which the temperature of the raw material is raised; a gasification reactor (50) for heating and pressurizing the raw material heated in the counter flow heat exchanger (30), gasifying the raw material in a supercritical state, and discharging a supercritical product stream which is to be introduced into the high-temperature side flow channel (37); and a product stream flow channel (55) for leading the product stream discharged from the gasification reactor (50) to the counter flow heat exchanger (30). The gasification system (100) is further provided with an external heating means (35) for introducing the raw material into the low-temperature side flow channel (36), taking out the introduced raw material at a position along the low-temperature flow channel (36), heating the raw material taken out, and returning the heated raw material to the low-temperature flow channel (36) at a position on the raw-material-wise-downstream side of the position at which the raw material has been taken out.
