Heating furnace, especially with gas and/or oil firing

Abstract

The invention relates to a heating oven (1) in particular with a gas and/or oil firing system. The heating oven comprises a combustion chamber (2) surrounded by heat storage elements, wherein respective first heat storage elements (3, 4; 27) are arranged at a first spacing parallel to respective walls (5, 6; 27) of the combustion chamber (2). Second heat storage elements (12, 14; 25) are arranged at a second spacing parallel to the respective outside of the first heat storage elements. The first spacing defines a first air channel (16, 17; 28) and the second spacing defines a second air channel (15, 18; 26) in each arrangement. The air in the first channel is heated by the walls of the combustion chamber, rises, cools down on the surrounding storage elements and sinks downwardly in the second air channel while giving up further energy to the heat storage elements. Thereafter, the cooled air again reaches the first air channel and the described flow cycle begins again in the heat exchanger.
