moisture content is an important parameter to control combustion in boilers. Simulated bagassewas used to monitor the effects of moisture content on gross calorific value (GCV) and net calorific value(NCV) and equilibrium analysis. So burning of bagasse at suitable level of moisture is essential from the viewpoint of boiler performance.

Coal ash, also known as coal combustion residuals (CCRs), is the particulate residue that remains from burning coal.Depending on the chemical composition of the coal burned, this residue may contain toxic substances and pose a health risk to workers in coal-fired power plants and residents living near coal ash disposal sites.
Coal is the main fuel for power generation in Mongolia. The quality of coal is determined by ash and moisture content in coal and its caloriˇc value. An important characteristic for the quality and price of coal is ash content in coal. Nowadays the old chemical technique is used in the power stations for determination of ash content .
Coal is the primary fuel for producing Electricity. Some of the characteristics of coal have profound influence on the day to day working and economics of the power plant. This article discusses Calorific Value and Moisture. Calorific value is the most important parameter that determines the economics of the power plant operation. It indicates the amount of heat that is released when the coal ...
= Ash(ar) + Total Moisture; Hydrogen in Coal: Refer to ASTM 3180 / ISO 1170 In as much as hydrogen values may be reported on the basis of containing or not containing the hydrogen in water (moisture) associated with the sample, alternative conversion procedures are defined below.
When the coal is removed from the mills through a blast of hot air, if the coal is too wet, the drying out is ineffective and has a negative effect on the combustion of coal. In other words, if the total moisture content becomes too high, the amount of heat energy required to evaporate the moisture is greater than the boiler design allows.

Dry Ash Free (daf): excludes all Moisture & Ash The Proximate Analysis of any coal i.e. the % content of Moisture, Ash (A), Volatile Matter (VM), Fixed Carbon (FC)– also Sulphur (S)and Calorific Value (CV)– can be expressed on any of the above bases. Coal Conversion Facts .
The Moisture in the Coal is both these put together and is the "Total Moisture." A coal sampled at the mines having a moisture of 20%, after storage for a few weeks, when entering the boiler can have moisture of only 8%. If the Coal sampled at the mines has an HHV of 18800 kJ/kg the same coal at the boiler will have a higher HHV.
