FIELD: the invention refers to arrangements for firing solid fuel predominantly waste wood and peat. ^ SUBSTANCE: the arrangement has a mine for fuel feeding, a combustion chamber, a fire-grate, an arrangement with a nozzle end for feeding air of forced draught for firing fuel along the contour of the combustion chamber and an afterburner. The peculiarity of the arrangement is that the fire-grate is fulfilled out of disconnecting sections each of which is provided with a hollow insertion with a nozzle-end. At that the nozzle parts of the insertions along the contour of the combustion chamber are fulfilled in the shape of sections located at the level of the sheet of the fire-grate in parallel to it and connected with a collector of the arrangement for supply air of forced draught with possibility of regulating an effective cross-section of the feeding zone. The insertions are installed perpendicularly to the fire bars. The length of the insertion equals the width of the fire- grate. The number of the sections of the fire- grate is no less than two. ^ EFFECT: allows to increase productivity and exploiting reliability and also possibility of regulation of power in a wide range. ^ 3 cl, 1 dwg
