Some cities passed laws that only anthracite could be burned while within city limits. Bitumous has been burned for a lot longer than anthracite, it was not used as a fuel until the 19th century. Bitumous coal actually predates the Romans. For what it is worth diamonds are an even higher energy source than anthracite, and burns with little or no ash or soot. But it might be a bit pricey. <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f61b.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":p" title="Stick out tongue    :p"  data-smilie="7"data-shortname=":p" />There were a number of discussions about coal burning, prices, mining, and pollution on the Privateer Press forums. *dig, dig, dig!*<a href="http://forums.privateerpress.com/index.php?showtopic=27456&hl=coal" target="_blank">Prices</a><a href="http://forums.privateerpress.com/index.php?showtopic=27802&hl=coal" target="_blank">Mining</a><a href="http://forums.privateerpress.com/index.php?showtopic=29995&hl=coal" target="_blank">Pollution</a>And I think that I blathered about it a bit on the ENPublishing forum while talking about Steam & Steel.The Auld Grump, who recently finished rereading De Re Metallica, a book of mining techniques from the 16th Century... Very dry, but worth reading. (And this time I made it all the way through! <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile    :)"  data-smilie="1"data-shortname=":)" />)*EDIT* Yes sulphur is one of the contaminants, bitumous coal is extremely variable as to impurities, and can produce lumps of unburnable clinker in the firebox of the engine, and coat the stacks with something very much like tar.</blockquote>
