Stove with heat storage - has inner lining of prefabricated refractory pieces forming hearth and flue conduit

摘要

The stove has an exterior chamber (24) which surrounds a massive interior refractory material lining which is traversed by a conduit (4) connecting the hearth (3) to the flue. The conduit run extends the trajectory of hot combustion gases and augments the thermal exchange surfaces. The interior pieces are complementary (25), are assembled according to a determined pattern to make the flue conduit, and extend over all the interor stove perimeter. The pieces are cylindrical segments defined by two overlapping horizontal planes and their interior openings from the combustion chamber as well as the flue conduit.
