In many modern brickworks, bricks are usually fired in a continuously fired tunnel kiln, in which the bricks are fired as they move slowly through the kiln on conveyors, rails, or kiln cars, which achieves a more consistent brick product.
Many contemporary brick factories utilize continuous-fired tunnel kilns to fire their bricks. In these kilns, the bricks travel along conveyor belts, rails, or specialized car systems as they are heated, leading to a more uniform brick output.
