Title:
INTEGRATION OF COAL GRINDING-DRYING, COAL SUPPLYING, AND COAL GASIFICATION FOR ENTRAINED-FLOW GASIFICATION PLANTS
Document Type and Number:
WIPO Patent Application WO/2011/012392
Kind Code:
A3
Abstract:
In a device for grinding-drying fuel and supplying fuel for an entrained-flow gasification plant in which a pulverized fuel is gasified at a pressure between 0.1 and 1 MPa (1 and 10 bar) to a raw gas high in H and CO content, a device (3) for grinding and drying the raw fuel to pulverized fuel, a dust filter (4), a pulverized fuel silo (5), a sluice (6*) with conveyance at the pressure of the entrained-flow gasification plant, a supply vessel (9) and an entrained-flow gasification plant (10) are directly connected in series. In contrast to conventional devices, the process steps of coal preparation and conveying are minimized here by integration and thus the required expenditure is significantly reduced.
