INSULATION-FIREBOX BOTTOM

A firebox is the combustion chamber (as of a commercial gas fryer or steam boiler) that contains and confines a flame.

Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
