Conifer wood tends to trap the wood gas inside of the log.
As the piece of wood gets hot, high gas pressure can build up until it finally forces its way out. When the fire crackles due to the gas explosion, sparks come off and can be thrown several feet from the fire. Eucalyptus is famous for this. So the best way to enjoy an evergreen wood fire is in a fireplace with a spark screen. Spruce and fir also spark a lot, but they differ in that they make less soot in an open fire than pine and can be easier to clean up after you have enjoyed your fire.
