A coal fire will run longer between tendings and give more even temps. However, if your going to use coal. I'd swap out those cast firebox liners and line it with refractory material. The iron liners are usually meant for use with wood only. They may crack/warp using them with coal. Plus, the better insulating qualities of refractory will make the coal burn better.
The stock pot for brown stock must be kept at a slow boil for a steady 24 hours. And just as important is the ability to have one side of the bottom exposed to the heat the other side cooler. I do this now by placing the pot on two burners and having only one burner turned on the other burner is off. If you where to look inside the pot you would see bubbles on just the front side of the pot. This arrangement induces a convection, rolling (top to bottom) circulation pattern inside the pot itself. Heating the entire bottom of the pot results in a cloudy stock. A richer, deeper flavored stock is produced by this method as more flavor is extracted from the roasted bones.
Consequently, a consistent, steady, high degree of temp control over a 24 hour period of time is important. Coal is the fuel I need to use. I don't want to tend a wood fire all night, curled up sleeping on the cement floor like a malnourished apprentice in a French kitchen.
Can standard fire brick be cut, fit and mortared inside the fire box or will I need to use something more formable like Ramming Cement ?
