Selective Flocculation Flotation of Coal Gasification Fine Slag

Taiyuan Ligong Daxue xuebao
【Purposes】 During the flotation process, the fine gasification slag particles exhibit challenges such as micro-fine particle coagulation and moisture entrainment since the interlocking of inorganic minerals and residual carbon particles from coal ...

Swirl chamber for vitrification of fly ashes

E3S Web of Conferences, 2017
The study presents the concept of a swirl chamber used for vitrification of fly ashes. It assumes the use of coal dust in the process of fly ash melting. The coal dust supplied to the swirl chamber and gasified in the atmosphere of O2, CO2 and H2O allows

Utilization of lightweight materials made from coal gasification slags [PDF]

, 1999
The integrated-gasification combined-cycle (IGCC) process is an emerging technology that utilizes coal for power generation and production of chemical feedstocks. However, the process generates large amounts of solid waste, consisting of vitrified ash (slag) and some unconverted carbon.
