Abstract

Improvements introduced in the home and in the hot smoke duct (gases and hot products of combustion) of the steam furnaces with ring tubes, used mainly for the baking of bread and other similar food products, these improvements consisting in that in the construction of the hearth and the hot flue duct refractory masonry is eliminated, this is replaced by a sheet of refractory steel of adequate thickness that forms the flanks and hearth of the hearth and the hot flue duct. This sheet also provides the advantage of moderating the heat temperature that the aforementioned hearth and duct radiate on the tubular elements of the heated section of the steam tubes, providing a greater increase of said heated section of each tube and, for this is a better thermal performance of the home and the hot smoke duct. Mode of realization of the heated section of the steam tubes closed by themselves, consisting in that the heated section surrounds, externally, the entire radiant surface of the hearth and the hot flue duct (flanks and sky) allowing to achieve a better performance of the heat transfer of the hearth and the flue pipe in the heated section of the steam pipes. In fact, the heated section is double: one half to the left of the longitudinal axis of the hearth and the flue and the other to the right of the same axis. The heated section can thus feed the heating section with a very strong hot steam flow which favors the thermal elasticity of the furnace. That the two halves of the heated section are closed at the top forming a large elongated link, suitable to derive, in parallel, the elements of the tube that form the heating section of each tube. That the parallel horizontal derivation of the tube elements of the heating section facilitates the superposition of the cooking chambers and their heating with externally arranged tube elements with respect to the chambers themselves. This greatly facilitates the construction of these cameras. That the return joint section goes down below the cooking chambers to the paving of the ashtray and this provides the possibility of placing below the bread baking chambers, a chamber for the baking of pastry, or a stove to facilitate the fermentation of the dough.
