moisture content of coal. The Service will allow a calculated reduction of the taxable weight of coal for the weight of excess moisture, but only where the taxpayer can demonstrate through competent evidence that there is a reasonable basis for its determination of the existence and amount of excess moisture. 3. Costain Coal v. US 36 (Fed Cl 38).
Table of ContentsExperimental ApparatusCoal Samples and PreparationExperimental ProcedureResults and Discussion Fundamental problems exist with the drying of fine coal. The moisture content of fine coal after mechanical dewatering is often too high to allow the coal to be added directly to the coarser (plus ¼ in) fractions and it must be further dewatered.
The reduction of moisture levels in export coals has been an enduring priority for the Australian coal industry1. High moisture can lead to high transport costs, technical problems during conveying, handling and storage, lost sales opportunities and moisture penalties. The problem is .

The effects of coal moisture content on unit performance are presented in Figures 1 to 3. Figure 1 shows the reduction in total air, flue gas and coal flow rates as fuel moisture content is reduced. Corresponding reductions in fan and mill power are presented in Figure 2.
3. Moisture in coal contributes to spontaneous heating because it assists the oxidation process. Moisture content should be limited to 3 percent; sulphur content should be limited to 1 percent, "as mined." Coal having high moisture content should be segregated and used as quickly as possible.

Fig. 3 shows that moisture reduction occurred on each of the seven days for which the test was repeated, the values ranging from 0.1 to 0.7 wt%. Overall the mean reduction was 0.3 wt%, three times higher than the mean standard deviation of 0.1 wt%. Thus the moisture reduction was significant at a confidence level well in excess of 95%.
This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground engaging tools. ROM coal can have a large variability of moisture and maximum particle size. Handling
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

Gasification as incomplete combustion Gasification is most simply thought of as choked combustion or incomplete combustion. It is burning solid fuels like wood or coal without enough air to complete combustion, so the output gas still has combustion potential. The unburned gas is then piped away to burn elsewhere as needed. Gas produced by this method goes by a variety of names: wood gas ...
