COMBUSTIVE FURNACE Russian patent published in 2009 - IPC F24B9/04 F24B5/02 F24B7/04 

FIELD: heat engineering.

SUBSTANCE: combustive furnace relates to heating systems of rooms and is provided for individual and joint bathhouses. Combustive furnace contains fire chamber with fire grate and ashpit, chamber with heat-accumulating charging, bin-water heater with inclined straight chimney, introduced by open end into side wall of bin, and by closed - to combustian space. It is outfitted by air heaters system, in which there are included heat-exchange collectors, at inlet connected to gate device, installed in basis of ashpit, and heat-exchange devices with input inclined and output collectors. Fire chamber is implemented with bicurvature side surfaces and is outfitted by steam superheater, containing installed on-the-mitre to the front wall of fire chamber and communicated to bin-water heater U-shaped contour, formed successively by connected cylinders, filled by heat-accumulating material and connected to coil fixed over fire grate so that its outlet ports are directed towards to each other. Chamber for heat-accumulating chargin is implemented as L-shaped and connected by steam pipeline to water heater. Inclined pipe of water heater is introduced by closed end into top part of fire chamber and outfitted by crosspiece for water supply and steam withdrawal.

EFFECT: improvement of operating characteristics of furnace: increasing of thermal effectiveness, fuel efficiency and manufacturability at simultaneous simplification of its service conditions.
