SOLID FUEL COMBUSTION PLANT Russian patent published in 2022 - IPC F23B10/00 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy. The solid fuel combustion plant includes a casing made of steel sheet in the form of a horizontally positioned rectangular box with blind ends and mounted on a foundation. A technological hatch with a cover is located on one of the ends of the housing in its lower part, and the grate is installed horizontally inside the housing under the technological hatch. The ash removal pipe is installed in the lower part of the body under the grate at the end of the body, where the technological hatch is located, and on the other end of the body there is an ash removal pipe. Ribs in the form of steel plates are laid across the body and mounted vertically on the grate at a distance from each other inside the body. The combustion chamber is made of steel sheets with holes rigidly laid on the ribs across them and along the perimeter of the body surface up to the grate. A hatch with a cover for loading solid fuel into the combustion chamber is made in the form of a quadrangle and is located at the top in the side of the body and in its center, and a sheet with holes in the combustion chamber, located under the loading hatch, has an opening in the form of a quadrangle, where a removable cover with holes is installed. The smoke afterburning chamber consists of two blank rectangular ducts inserted into each other with a gap, where air is supplied through a pipe installed at one of the ends of the outer duct. At the same time, the smoke afterburning chamber is installed outside the furnace body on its upper part, and the lower part of the outer box is part of the installation body. At the other end of the chamber there is an opening for the passage of smoke connecting the inner box with the combustion chamber, while at the inner box of the chamber near the opening for the passage of smoke around the entire perimeter holes are formed for the passage of air into it, and at the other end of the inner box a vertical chimney is installed. In the gap between the boxes along them, ribs in the form of plates are installed vertically at a distance from each other, and collectors are installed outside the furnace body along its sides at a distance from each other for uniform air supply to the cavities formed by the body, ribs and the combustion chamber.

EFFECT: invention makes it possible to simplify the design of a solid fuel combustion plant.
