Never much problems until this year. this year it keeps building up coal gas. The basement started stinking, hubby had for the first time ever put a cover over the barrel coal bin. I complained about the smell, he took it off. Smell seemed to go away. Daughter home one day heard a loud noise called her dad, hubby came home and looked at the furnance, had a small explosion, and blew off the pipe. Had the chimmney cleaned. no problems there. Tonight had three small explosions that rocked the floor. Sounded like a car hit the house. Pipe is off, minimal damage to the furnance. Thankfully hubby is a professional carpenter, and he hoards coal furnace parts when he sees them. He replaced a funnel thingy and some other tubey thingy. Any ideas on why we are suddenly getting coal gas build up and gas explosions. Not sure where to look, but hubby hasn't done anything other than the lid, to the furnance this year.
Thanks for any advice.

not sure where you get coal but your either burning buckwheat (the size smaller then pea) or superior breaker pea which is smaller then the others. this is most likly the case and if you got it from the same supplier there a good chance they either sold buckwheat or switch who they got it from and the pea is from superior...... BTW goto the boiler section and to the AA library and read the (bureau of mines report a lot of good info)....
one more thing if the anthrastat is the orginal it may be out of calibration making the ash bed more compact which could case the POP.
