Abstract
A boiler tube protection block, comprising an essentially parallellogram shaped body (11), an annular cut-out at all four corners, with the cutting point of two adjacent sides as a center. An assembly of a boiler protection block and a ferrule (21) with a radius essentially corresponding to the central annular hole of the block. A boiler, and a method for furnishing a boiler inner wall, comprising applying protection blocks against the wall, and arranging ferrules through at least the annular cut-outs.
Claims20
A boiler wall protection block for building a boiler wall, comprising:
- an essentially parallelogram shaped body;
- and
- an annular cut-out at all four corners, with the cutting point of two adjacent sides as a centre, wherein each of the annular cut-outs is arranged to receive at least part of a ferrule;
- wherein the protection block and the ferrule are distinct, non-integrated structures;
- and
- wherein each side of the protection block has a protrusion corresponding to a recess in a neighboring protection block and a recess corresponding to a protrusion in the neighboring protection block preventing direct radiation of heat from reaching the boiler wall.
A method for furnishing a boiler inner wall, comprising:
- applying boiler wall protection blocks against the wall, and
- inserting ferrules through annular cut-outs of the boiler wall protection blocks to secure the boiler wall protection blocks,
- wherein the protection blocks and the ferrules are distinct, non-integrated structures, and
- wherein each of the protection blocks has an essentially parallelogram shaped body f with the annular cut-outs at all four corners, with the cutting point of two adjacent sides as a centre,
- wherein each side of the protection block has a protrusion corresponding to a recess in a neighboring protection block and a recess corresponding to a protrusion in the neighboring protection block preventing direct radiation of heat from reaching the boiler wall.
A boiler wall protection sub-block, comprising a part of a boiler wall protection block wherein the part corresponds to a section of the boiler wall protection block from one annular cut-out to an adjacent one or to a section of the block from one annular cut-out to an opposite one, wherein each of the annular cut-outs is arranged to receive at least part of a ferrule,
- wherein the part of the boiler wall protection block and the ferrule are distinct, non-integrated structures, and
- wherein the protection block has an essentially parallelogram shaped body of which with the annular cut-outs at all four corners, with the cutting point of two adjacent sides as a centre,
- wherein each side of the protection block has a protrusion corresponding to a recess in a neighboring protection block and a recess corresponding to a protrusion in the neighboring protection block preventing direct radiation of heat from reaching the boiler wall.
