This results in higher fuel flow, higher stack flue gas flow, higher parasitic power, lower plant efficiency, and higher mill maintenance costs compared to low-moisture coals. Efforts are underway in Europe and Australia to develop efficient coal dewatering and drying processes. Thermal drying and dewatering and mechanical dewatering are employed.

11.10 Coal Cleaning. A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1. In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions.
The process flow of fine coal rejects is organized as illustrated in Fig. 2, where four processes are involved: material input, processing, products, and final values. The four products generated during the process are saleable coal, tailings, water and land conservation, and GHG reduction. Option 1. Dewatering the tailings using belt press ...
The scrubber purge stream—or flue gas desulfurization (FGD) wastewater—is most often treated in a dedicated wastewater facility rather than a plant's existing wastewater treatment system, because the power plant's existing wastewater treatment facility may not have adequate capacity, be able to receive a high chloride wastewater stream, or be …
However, in the dewatering process currently used in coal preparation plants, coal fines smaller than 45 micrometers are lost, and in many other plants, coal fines up to 100 micrometers are also wasted. Coal with smaller particle sizes are of greater value as power plant fuel due to their higher purity and larger surface area.
IEA Clean Coal Centre – Water conservation in coal-fired power plants 9 between power plant operators and other water users is likely to escalate, and climate change could further exacerbate the situation. Regulatory restraints by governments may impose limits on, or increase the cost of, fresh water usage by power plants.
