This is a test I did a while ago to simulate a barrel igniting and exploding in UE4. Lots of things that can be tweaked, mostly the sprite sheets used and the timings in which particles spawn. Would probably re-do it in Niagara as this was possibly the last thing I did in Cascade. Simulations done using EmberGen, Barrel taken from the Megascans asset library
