Effects of coal moisture control and coal .

In this work, the influences of coal moisture control (CMC) and coal briquette technology on structure and reactivity of cokes were investigated by adding a certain proportion of briquette into raw coal with different moisture. The coking experiments were carried out in a tested coke-oven of 70 kg, and the properties of as-obtained coke were analyzed by X-ray diffraction (XRD), scanning ...

The heat of wetting and its effect on coal .

The effect of moisture on the spontaneous combustion of coal is highly complex and has long been an important topic of research. Kadioglu and Varamaz [ 9 ] analyzed the characteristics of the spontaneous combustion of coals using the crossing point method and found that the risk of spontaneous combustion increased as the air-drying time increased.

Effect of moisture in coal on station heat rate and .

The effects of moisture in coal on the power block (boiler-turbine-generator unit) are decreased in boiler efficiency (Figure 7), decreased overall unit efficiency (increase in heat rate) (Figure 8) and decrease in unit load.. The boiler efficiency decreases due to increase in moisture and the unit heat rate increases. This results in increased cost of generation.
