A quick description of a coal burning stove: It must have grates, preferably shaker grates with an external handle to shake them. Below the grates is an ashpan. The ashpan drawer must have a door with an adjustable air vent in the door. Coal only burns with all the air getting to the coal fire from below, and the air pulled through the coal bed by the draft of the chimney.
As for your chimney, if it is terracotta lined, and the terracotta tiles are not cracked then whoever told you that you need a SS liner for your chimney is just trying to sell you a liner. a terracotta lined chimney is the best chinmey there is. If you are burning wood, the cool terracotta liner MAY pick up more creosote than a SS liner but it is in no way unsafe if the chimney is cleaned if it gets an accumulation of creosote.
It doesn't appear that there is enough room to install a piece of metal chimney flue into the top of the stove inside the chimney.. If there is enough room, you MUST seal the pipe in the chimney with a piece of steel to block off the rest of the damper /chimney opening. You cannot have any chance of the exhaust gases from the coal fire to leak into the house.. The gasses from coal contain a lot of Carbon Monoxide, and this is deadly.
I hope the above helps
hEY GREG THANKS ALOT, i WILL SEND SOME PICS OF THE STOVE, it has a fan blower in front of it but theres a vent that opens and closes under the fan and when I burn wood I can see the air from below being controlled at the grate, the grate has a H shaped metal thing that rides across the grate and can go from right to left I have been moving it with a hammer when I clean the stove, I have to remove the fan to see if there is another control, there isn't any clean out that I can see underneath but where else would the ashes be going thanks
