Moisture Correction for Coal Analysis - Bright Hub

2010-1-10  The moisture in Coal consists of two parts. One is the moisture held within the molecular structure of the coal called “inherent moisture.” Removal takes place only at temperatures greater than 100 deg C. The second part is the moisture that is on the surface of the coal. This is normally due to the conditions and locations of the mines.

Pulverizer Application for High Volatile High Moisture Coals

2018-2-1  moisture reductions while simultaneously producing the lowest practicable pulverizer inlet temperatures. Since regenerative type air heaters are practically limited to 650-700 OF, the flexibility in the pulverizer system design lies in the selection of air to coal ratios to handle the specific coal property.

Drying Technologies of Lignite Coals – IspatGuru

2018-7-20  The moisture adheres to the surface of coal particulates or in the bigger capillary cavities. It is the moisture, which can be removed by the coal drying in air at ambient temperature (around 25 deg C). It depends on water conditions in deposit. Inherent moisture –

Coal Drying Improves Performance and Reduces Emissions

2017-9-6  A baseline level of 40 percent fuel moisture was assumed in the calculations. 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.

Laboratory Sample Pulverizers

Pulverizer performance is not appreciably affected by moisture content or size until the proportion of dried, smaller-size fraction is somewhat greater than 35 percent. Test results in which the mixture contains 35 percent dried fines are very similar to those obtained in the tests in which all feed is at natural moisture content or when ...

Biomass Conversions: Not So Cut and Dried

2010-10-14  Pulverizer primary air can be reduced (within limits) to lower the nozzle velocity and achieve higher biomass inputs, but a reduction in coal throughput and possibly boiler load may result. Even with adjusted primary air-to-coal ratios, flame stability can suffer with higher moisture biomass.
