HEATING DEVICE Russian patent published in 2024 - IPC F24B1/02 F24B7/00 

FIELD: machine building.

SUBSTANCE: invention relates to the field of heat exchange equipment, namely to devices for air heating of premises for various purposes when using all types of solid fuel. Heating device includes a furnace chamber, the walls of which are made along the outline of refractory bricks, a heat exchanger, a chimney, a smoke gate valve. Furnace chamber is made with a furnace door for solid fuel loading. Heat exchanger is located at the side wall inside the heating device and is made from the bottom upwards from the combustion chamber to the chimney. Besides, the heat exchanger is made as single-section and consists of at least three vertical metal round pipes, to which inlet lower and outlet upper pipes are welded at right angle, made for passage of hot air through them. At the same time the upper branch pipes are made with adjustable movable shutters. One-piece rectangular plate is welded to vertical metal round pipes on the side of internal surface of the furnace chamber by means of metal angles along the whole width and height of vertical metal round pipes. Furnace chamber consists of a furnace which is divided by the arch of a cast-iron plate into two parts, an upper and a lower one. Cast iron plate separates the lower part of the furnace chamber from the smoke channels from above and forms a niche open on the side with a vault above the cooking area of the cast iron plate in the heating device masonry with the possibility of providing drying functions. Furnace door is made with holes in the lower part, located along the width in two rows in staggered order and with possibility of their overlapping by movable flat plate with handle moved in guides, horizontally welded from outside to furnace door wall.

EFFECT: expansion of functional capabilities with increased efficiency and reduction of transverse dimensions.
