FURNACE Russian patent published in 2009 - IPC F24B1/00 

FIELD: heating.

SUBSTANCE: furnace consists of the inner and the outer furnace packages with a chimney and an air vent. The inner furnace package consists of a combustion chamber equipped with a fire grate, an ash tray, a longitudinal baffle and cross-baffles, the baffles forming vertical and horizontal furnace gas ducts communicating with the chimney. The longitudinal baffle is arranged along the whole of the inner furnace package length with a clearance maintained between the baffle and the upper wall. The first cross baffle is arranged along the whole of the inner furnace package height between the longitudinal baffle and one of the side walls. The above longitudinal baffle and cross baffle are positioned so that to provide for formation of a downward duct and an upward duct. The second cross baffle is mounted under the ash tray so that to enable the longitudinal baffle resting on it and positioned so that a clearance is maintained between the baffle and the other side wall. The outer furnace package is mounted with a clearance maintained between it and the inner furnace package on all its sides; in the longitudinal baffle and the first cross baffle there are through-holes arranged accordingly connecting the furnace to the downward duct and the downward duct and the upward duct - to each other. The clearance between the longitudinal baffle and the inner furnace package upper wall is confined to the downward duct zone.

EFFECT: furnace design simplification combined with enhanced efficiency.
