For this analysis, a coal sample is combusted in an ultimate analyzer, which measures the weight percent of carbon, hydrogen, nitrogen, sulfur, and ash from a coal sample. The total carbon, hydrogen, and nitrogen are determined at the same time from the same sample in the analyzer. Total oxygen is calculated from the other values.

The objective of ultimate coal analysis of coal is to determine the amount of fixed carbon (FC), volatile matters (VM), moisture, and ash within the coal sample. The variables are measured in weight percent (wt. %) and are calculated in several different bases. AR (as-received) basis is the most widely used basis in industrial applications.

1 MJ/Kg = 429.92255 BTU/lb = 238.84586 CAL/g For reference: 1J = 1Ws (1 Watt for 1 second) If the power station conversion efficiency from coal to electricity would be then 1 gram of coal with a CV of 26KJ/g would result in 26000 WS = 7.2 Watt Hour. A 40W bulb can run it for 650 seconds or 10.8 minutes.
