Abstract
A method of building refractory protection walls of furnaces, ovens or combustion chambers, notably but not exclusively for boilers for incinerating garbage and refuse, is proposed for protecting the hearth walls by means of a refractory wall (4) consisting of a plurality of shaped fire-bricks (5) each provided with at least one blind recess (6, 11) disposed at the level of the fixing means of the panel (1) to be protected which consist of fixing studs (7) projecting from the panel surface and adapted to engage the corresponding blind recesses (6, 11) so that each fire-brick (5) is suspended from these studs (7) and self-locked in position by at least the next overlying fire-brick.
Claims4
A fire-brick for use in a refractory wall composed of a plurality of shaped fire-bricks for the protection of a hearth wall, the hearth wall being provided with panels composed of a cluster of tubes assembled by welded fins and having a plurality of fixing studs, said fire-bricks having a volumetric configuration consistent with said panel, each fire-brick having an inner face and an outer face, and comprising on its inner face at lease one blind recess having a longitudinal axis extending across and inclined to said inner face, the fixing studs of said panels matching with and being adapted to engage the blind recesses of the plurality of fire-bricks composing the refractory wall, each fire-brick being suspended from corresponding fixing studs to be held in position by gravity and self-locked at least by the overlying adjacent fire-brick of the refractory wall.
