Summary	0009795: Ignition temperatures for fuels too high, qualify them as "fire-safe"
Description	According to this webpage: http://www.engineeringtoolbox.com/fuels-ignition-temperatures-d_171.html The "auto-ignition temperature" of some materials (in Celsius): Bituminous coal 454 Charcoal 349 Coke 700 Lignite - glow point 526 Comparatively, in game the ignition temperature of fuels is 11440 U (800 C). Using the above values as a reference, the ignition temperatures (in Urists = [CELSIUS] * 9/5 + 10000) should be: Bituminous coal 10817 Charcoal 10628 Coke 11260 Lignite 10947 Those changes would make bituminous coal, charcoal, and lignite non-fire-safe. The new ignition temperature for coke is still above the fire-safety threshold, but that reference ignition temperature might represent a more heavily refined modern coke than would be available with Dwarf Fortress technology. It could be adjusted down to slightly below the fire-safety temperature to prevent building coke-fired furnaces out of coke.
