SOLID FUEL FIRE-TUBE BOILER Russian patent published in 2017 - IPC F23B30/10 F23J1/00 

FIELD: heating system.

SUBSTANCE: solid fuel fire-tube boiler contains a front loading unit for solid fuel, a horizontal cylindrical boiler water tank and an elliptical flame tube with a horizontally oriented ellipse inserted into it, terminating in a cylindrical fire chamber with diverting smoke tubes, the lower part of the fire chamber is provided with a chimney forming a cooled slag mine. The fire tube is equipped with a system of shuffling slats of a pendulum type, for which a horizontal run in the form of a hollow tube is installed on the vertical axis of the flame tube, with the possibility of rotating it at the passage nodes through the front and rear walls of the flame tube, the rotary chamber and the boiler; radially connected to the girder down and diluted at a central angle of not more than 80°, two rows of rigid rods and shufflers fixed at their free ends, placed along the flame tube symmetrically with respect to its vertical axis, with the possibility of their forced oscillations about this axis according to a given program. Shurting bars are installed along the flame tube at an angle to the generatrix of the flame tube with an ascent along the inner surface from the front to the rear.

EFFECT: complete burning of fuel in focal residues and increase in fuel combustion efficiency.
