I have a few questions about the different types of coal and the kind of ash they produce. Some people said that I should always try to get hard coal and I'm assuming that's what I'm running now from looking at my ashes. Others tell me to try and get the coal that produces very fine ash as that means it is of a better quality but is softer. So I'm not sure which way to go here. Does one produce better heat? Whats your opinion/experience with different types of coal and ash?
Here are some pictures of what my ash looks like now.
