2021-10-21  Raw water use in IGCC plants is lower than in pulverized coal plants. Without CCS, PC plants have a much higher steam turbine output, requiring more cooling water and condenser duties (typical raw water use ratio of 1.7:1.0). With carbon capture, the difference in water use is even more dramatic (2.5:1.0), as the chemical absorption process for

Influence of Combined Water in Coal on Pre-reduction of

Volatile matter, which occupies more than 20 mass% in non-coking coal, is not utilized when the coal is fed directly into the smelting furnace. Its presence may even cause adverse effects in the operation. Therefore, the fundamental study on pre-reduction of iron oxide was carried out in order to investigate the conditions for efficient use of volatile matter in an iron bath smelting reduction
