    摘要： A hot blast stove dome comprises a first dome portion adapted for support on a combustion chamber wall of a hot blast stove, and a second dome portion adapted for support on a checker chamber wall of a hot blast stove, wherein a vertical expansion joint is provided between the first dome portion and the second dome portion and is adapted to allow the first dome portion and the second dome portion to independently accommodate vertical expansion of their respective supporting walls. The dome is suitably provided in a hot blast stove which comprises a combustion chamber, a checker chamber, a cylindrical housing comprising a combustion chamber wall and a checker chamber wall.

    摘要： The method is to determine a leak in a breast wall of a regenerative heat recuperator having a combustion chamber and a heat storage chamber containing a heat storage medium adjacent to the combustion chamber and separated therefrom by a breast wall. The combustion chamber has inlet means for fuel and air and the heat storage chamber has outlet means for the flue gases which pass into it from the combustion chamber. To achieve a simple and accurate determination, the method comprises the steps of (i) while passing gas through the recuperator, introducing to the inlet means a marker gas which undergoes an irreversible change at a temperature prevailing in the recuperator, and (ii) detecting the presence of the marker gas in the gases passing out of the outlet means.

    摘要： A heat regenerator of the type comprising, within a wall of refractory material, a space containing a pile of bricks (checker brick) and a burner stack separated therefrom by a separating wall, the cylindrical wall of the heat regenerator and the separating wall consisting of more than one layer of refractory material, in which at least for part of the walls and in particular for the separating wall between checker bricks and burner stack, at least one of the layers of refractory material is subdivided by a vertically extending expansion joint to avoid cracks, damage and gas leaks through the concerning wall or walls. Preferably there is a number of such joints in the separating wall, extending at least over the height of the lower half of the burner stack. The facing edges of the layer at the joint have grooves with sealing bricks engaging therein or tongues and grooves engaging sealingly, with a compressible filler of ceramic wool or felt sealing the joint in cold condition of the regenerator.
