Positioned under upper cone ( 6 ) is second inverted truncated lower sheet metal cone ( 8 ) of air draft. Both truncated cones ( 6, 8 ) are rigidly positioned, one relative to the other, with axial gap (h) determined by means of circumferential sheet metal ring ( 7 ), rigidly connected to them and positioned at external circumference thereof. The lower part of upper cone ( 6 ) connects to grate ( 3 ), under which sheet metal ash pan ( 4 ) is positioned. Circumferential sheet metal ring ( 7 ) of stove rests on supporting structure ( 5 ).
