A variety of bituminous coal, called cannel coal, is characterized by an unusually high percentage of volatile matter, which causes it to ignite easily.
Anthracite has a higher fuel ratio than bituminous coal; that is, it has more fixed carbon in relation to volatile matter.
For the moisture, volatile matter, fixed carbon and ash, the determinations are the same, but a special distillation must be made to obtain a sufficient quantity of the volatile products for subsequent examination.
If this tar is subjected to the standard proximate analysis, it will be shown that from 40 to 50% of it is fixed carbon, although it left the gas generator as volatile matter.
The coal which analyzes 45% ofvolatile matter evolves a much greater volume of gases and tar vapors than that analyzing only 15 per cent.
Some of the carbon constituent is combined with hydrogen and this, together with other gaseous substances driven off by the application of heat, form that portion of the coal known as volatile matter.
As stated, the difficulty of burning bituminous coals successfully will increase with the increase in volatile matter.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "volatile matter" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
