摘要： The present invention concerns a boiler (1) with a circulation system for boiler water which comprises water pipes (3) arranged to circulate boiler water or steam through the pipes with a cooled partition (12) arranged to cool a selected, exposed part of the steam boiler (1). In accordance with the present invention, the cooled partition (12) comprises a number of outer tubes (13), each of which has an inner tube (14) arranged in the outer tube (13), and which outer tube (13), at an upper end (15), has an open connection to a pipe (3) for cooling media, in which pipe a flow is established. Adjacent outer tubes (13) may appropriately be connected with heat-conducting connectors (40) over at least 70% of the axial length of the outer tubes and embedded in a fireproof material (41) that forms the outer surface of the partition.

摘要： A tube shield (10) having a cylindrical shape and adapted to be attached with refractory cement (R) around an outer peripheral surface of a boiler tube (T), wherein said tube shield (10) comprising at least two tube shield parts (1) for surrounding the boiler tube (T). The shield parts having complimentary parting surfaces for defining a gap, between abutting complimentary parting surfaces of adjacent shield parts when the shield parts are attached with refractory cement (R) around the boiler tube (T). Each shield part encloses 140-220° preferably , 180° of the total circumference of the boiler tube (T) . Each complimentary parting surface is configured in a dovetail form such that one shield part (1a) is locking into the other shield part (1b) with dovetail protrusions (DP) located in dovetail slots (DS) in the other shield part (1).
