Coal Quality
Posted: Sun. Dec. 19, 2010 10:03 am
this is my second year burning coal. last year bought 3 ton antracite from boslers here in ohio. It was glossy and burned with a blue flame. This year the coal was dull and the flame is yellow and seems to fracture alot when hot could you guy's tell me the difference in the two. thank's ( I have learned a great deal from all on this forum)
