Char–Wall Interaction and Properties of Slag Waste in Entrained-Flow Gasification of Coal

Energy & Fuels, 2011
The properties of solid wastes (fly and bottom ashes) generated from an industrial-scale pressurized entrained-flow gasifier were investigated. Bottom ashes consist of coarse slag granules and fine slag particles, both retrieved from the quench bath but characterized by distinctively different morphological and physicochemical properties ...

Adaptability of Coal Gasification in Molten Blast Furnace Slag on Coal Samples and Granularities

Energy & Fuels, 2011
In this work, coal gasification in molten blast furnace (BF) slag was performed at atmospheric pressure in a molten bath reactor in the temperature range from 1573 to 1773 K. The effects of coal samples and coal granularities on the gasification reaction rate, carbon conversion, and gas composition were studied, and the kinetic mechanism function was ...

Char-slag transition during pulverized coal gasification

2012
In coal gasification the char-slag transition is a process in which porous char transforms into molten slag at temperatures above ash fluid temperature. It is associated with physical changes of the char particle, such as particle density, size, porous structure and mineral-carbon association.

Valorization of oily sludge with coal gasification slag via catalytic pyrolysis

Bioresource Technology
The treatment of oily sludge (OS) and coal gasification slag (CGS), which are abundant hazardous solid wastes in the energy industry, is still challenging. Herein, we demonstrate the CGS catalyzed OS pyrolysis in a fixed-bed reactor, and the effect of CGS to OS ratios on the product distribution was investigated at temperatures of 400 to 800 °C ...

Distribution, occurrence, and leachability of typical heavy metals in coal gasification slag

Science of The Total Environment
Coal gasification slag (CGS) contains variable amounts of heavy metals, which can negatively impact the environment. The mineral composition, element distribution, occurrence, and leaching characteristics of heavy metals in coal gasification coarse slag (CGCS) and coal gasification fine slag (CGFS) are studied to explain the leaching behavior of heavy ...

A pilot scale test on the fluidized melting combustion of coal gasification fine slag

Waste Management
To address the issue of coal gasification fine slag (CGFS) disposal, a novel fluidized melting combustion (FMC) process has been proposed. In this study, the operating feasibility, combustion performance and gas pollutant emission were assessed through 0.4 MW pilot-scale test.
