The coal is lignite to lignite-A to sub bituminous B and C in character with an average heating value of 6000 BTU/lb.
The density at 20[degrees]C and the lower heating value were collected in triplicate, the results were submitted to analysis of variance (ANOVA) and the means were compared by Tukey test, adopting the significance level of 1-5% using the statistical package version Assistat[R] 7.

This confirmed that the straight-cut probe ingested some liquids, causing a bias in the sample heating value between 5-7 Btu/scf.
It should be noted, that heating value, proximate, and ultimate analysis was conducted for individual and blended biomass as presented in Table 1.
The Indian coal unlike the rest of the world has the highest arc contents, 25%-45%, with low heating value, thus to generate one unit electricity, coal power plants emit one kilogram of carbon dioxide.
To determine the rank of coal, laboratory tests such as proximate analysis (moisture, volatile matter, fixed carbon and ash), ultimate analysis (elemental composition of organic fraction on weight percent basis; carbon, hydrogen, oxygen, nitrogen and sulfur), heating value, hard groove grindability index (HGI) and petrographic analysis were carried out.
Coal is also one of alternative options and cheap but due to low heating value, handling issues like self ignition and other impurities not allowing end users to opt coal for power generation in limited scale, therefore, coal option can only be considered in large scale at Government level and coal gas or Syn gas need an expensive infrastructure either produced by gasifier or underground coal gasification method.
The CalorVal BTU calorific analyzer micro-combustion calorimeter features a unique construction and operating technology that make it suitable for directly measuring the heating value of varying wastegas streams for flare-stack applications.
This provided the feedstocks' "higher heating value," which indicates how much energy is released via combustion.
