GRATE CONSISTING OF FIRE BARS FOR COMBUSTION AND INSTALLATION METHOD OF FIRE BARS IN GRATE AND THEIR REMOVAL THEREFROM Russian patent published in 2016 - IPC F23H7/08 F23H17/00 

FIELD: energetics.

SUBSTANCE: invention relates to power engineering. Grate consists of several stages, including large number of first and second grates (A, B), arranged in rows close to each other and in rows one above another and forming by their top support surfaces (2) stepped surface (17) for combustion. Invention consists in, that first grates (A) at its width (b) are at least once in support surface (2) area form lower support surface (2) for burnt material (14) by means of ledge (7) inside towards longitudinal central plane (10), than second grates (B), and second grates (B) in support surface (2) area have to form overlap (9) with first grates (A) by means of projection (8) in width (b) to outside support surface (2) of larger width (b′). Additionally, second grates (B) contain at least one increasing width (b′) to width (b′′) pin (5), introduced into corresponding pocket (6) of first grates (A).

EFFECT: invention allows improving grate operating reliability, simple replacement of individual grates.
