Molten slag, the high‐temperature by-product of metallurgical operations, contains substantial thermal energy at temperatures often exceeding 1 500 °C. Harnessing this energy through heat recovery and ...

Coal gasification generates substantial quantities of coarse and fine slag alongside residual carbon and inorganic residues. Historically treated as waste, these by-products are now recognised as ...

Coal remains the most stable low-cost source of energy, but its lower qualities challenge users to meet stringent environmental regulations. The first step in any modification or fuel switching of a ...
