The decrease in coal utilization rate resulted from the increased higher heating value (HHV) of the coal. The reducedmoisture coal also had improved grindability, thus mill power decreased by almost 10%. This allowed the unit to be operated with six mills in service, instead of the customary seven or eight.

These factors are coal particle size, coal moisture content, binder percentage, and pellet cure time. Properties of the pellets were investigated using the following tests: higher heating value, proximate analysis, ultimate analysis, mass density, particle density, indirect tensile strength, impact resistance, and abrasion resistance.
How to Calculate Higher Heating Value | Hunker
Apr 12, 2017· Higher heating value (HHV) is one measure of the energy content of a material. It is almost exclusively used in measuring energy content for fossil fuels and their alternatives, such as oil, coal, natural gas and biomass. HHV is the upper end of the energy content, and it includes the energy in water evaporated from the fuel as it is combusted.

Physicochemical characterization of low rank Nigerian coals
SKJ can be attributed to the higher values of O presented in Table 1. Consequently, AFZ coal showed the highest value of C content and lowest value of O content which is translated in the highest calorific of the coals investigated. Hence, the results indicate that reactivity and maturity of the coal increases in the order; GMG SKJ AFZ.

Lower and Higher Heating Values of Coal: Why do they exist ...
Oct 29, 2015· 1. The coal may have some residual water in it, which would lower the effective heating value because that water would subsequently be vaporized. 2. The coal maybe have other hydrocarbons embedded in it. These would produce water when combusted. The HHV for natural gas about 10% higher than the LHV. The HHV for coal is about 5% higher than LHV.

than is the case with bituminous coal. The disadvantages arise because: (1) lignite's lower heating value means more fuel must be handled to produce a given amount of power; (2) the energy and maintenance costs of coal handling equipment are higher; (3) the high inherent moisture content of lignite decreases
