Abstract
A ceramic gas burner for a hot-blast stove has a burner crown essentially composed of a plurality of shaped bricks which define terminal portions of at least one combustion air duct and at least one gas duct of said burner for flow of respectively combustion air and gas. A simple and inexpensive structure is obtained when the bricks are of at most two principal types in respective layers. The bricks of each type are identical, but may be of a subsidiary type of which two bricks combine to form one brick of the principal type.
