Document Type and Number:
WIPO Patent Application WO/2019/177149
Kind Code:
A1
Abstract:
This gasification system comprises a drying means 2, a pulverisation means 3, air-flow conveyance means 5, 6, 12 and a gasification furnace 19. The drying means 2 dries a solid fuel 1, and the pulverisation means 3 pulverises the solid fuel 1. The air-flow conveyance means 5, 6, 12 conveys the solid fuel dried by the drying means 2 and pulverised by the pulverisation means 3 to the gasification furnace 19 by air flow. The gasification furnace 19 gasifies the solid fuel conveyed by the air-flow conveyance means 5, 6, 12 by air flow. The gasification system is provided with a powder supply system that supplies moisture-absorbing powder 4A, 4B containing an inorganic substance to at least one point from the pulverisation means 3 to the gasification furnace 19.
