METHOD FOR BRICK BAKING Russian patent published in 2000 - IPC

FIELD: production of building materials. SUBSTANCE: a moving hearth is installed in the kiln tunnel, the hearth carries supports for placement of brick courses with a space between bricks equal to 0.3 to 1.7 of the brick thickness, and a space between tiers equal to 0.8 to 2.5 of the brick thickness. At baking of hollow bricks the space between tiers is decreased by 0.4 to 0.9 of the brick hollowness. At a continuous movement of the hearth in the kiln the torch flame passes between the spaces and transfers heat energy to the brick, the selected spaces uniformly distribute the heat energy in compliance with the dimensions of surfaces of brick faces. EFFECT: enhanced quality of bricks. 1 dwg, 2 ex
