So, in many cases companies need only activity data, such as the amount of distance traveled or fuel combusted, to calculate their emissions. The default emission factors are averages based on the most extensive data sets available and they are largely identical to those used by the Intergovernmental Panel on Climate Chage (IPCC), the premier ...
Main steam is at 2,000 psia, 1,000 F, and has an enthalpy of 1474.1 Btu/lbm. The steam extraction (cold reheat) pressure is 300 psia, which equates (isentropically) to a cold reheat temperature of ...
The bomb calorimeter has historically been used to calculate coal's gross calorific value (GCV). However, for many years, engineers and scientists were trying to measure coal's GCV without a bomb calorimeter, using only laboratory-derived ultimate and/or proximate analyses to eliminate tedious and time-consuming laboratory analyses. …
COAL PETROGRAPHY Coal petrography is a microscopic technique used to determine a coals rank (degree of coalification) and type (amount and class of macerals). Macerals in coal are analogous to minerals in igneous rocks and are determined by examining polished specimens of minus 20 mesh prepared coal. Petrography is primarily

The correction to the gross calorific value is 586 cal/g water (latent heat of steam = 586 cal/g). The water referred to is the weight of water produced by the complete combustion of unit weight of coal plus the water existing as moisture in the coal. The former is calculated from a known hydrogen content of the coal:
The gross calorific value (GCV) of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal.
