Fine slag (FS) is an unavoidable by-product of coal gasification. FS, which is a simple heap of solid waste left in the open air, easily causes environmental pollution and has a low resource utilization rate, thereby restricting the development of energy-saving coal gasification technologies. The multiscale analysis of FS performed in this study …

The settling rate of entrained droplets can be increased by modifying the slag composition and, thus, the slag properties, which are known to influence the settling rate. The knowledge of industrial CaO slag modification in a reduced iron silicate slag with a Fe/SiO 2 ratio close to unity is limited. An industrial trial was thus conducted in an ...

Slag is the by-product of iron- and steelmaking processes. Normally, around half to one tonne of slag would be generated for yielding one tonne of rolled iron or steel (Lobato et al. 2015).It was reported that the world steel production was 1.9 billion tonnes in 2016, which suggested that at least around 1 billion tonnes of slag is produced during …
