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.

A ceramic gas burner for a hot-blast stove comprising 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, said bricks being of at most two principal types and said bricks of one of said principal types are located relative to said bricks of the other said principal type by cooperating projections and recesses on the bricks.
A ceramic gas burner for a hot-blast stove comprising 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, wherein said bricks are of a first principal type in a first layer and a second said principal type in a second layer on top of said first layer,
- said bricks of said first principal type having a general outline shape consisting of generally parallel top and bottom faces and four side faces, said side faces being perpendicular to said bottom face over a part of the height of the brick and said top face being smaller in at least one dimension than said bottom face,
- said bricks of said second principal type having an upwardly tapering trapezoidal shape as seen in vertical cross-section, having generally parallel top and bottom faces.
