Abstract: PURPOSE:To carry out a high complete combustion and reduce a load at a grid after combustion by a method wherein a plurality of protrusion-type blocks projected upwardly from a grid surface and formed with an inclined receiving surface slanted from a front lower part toward a rear upper part are disposed by a predetermined spaced- apart relation from a grade cutter toward a rearward position. CONSTITUTION:A protrusion-type block 1 to be fixed to an upper surface of a grid block 11 is formed into a hollow frust-quadorangular prism by Cr-Si heat-resistant cast steel, for example. It forms a receiving surface 1d in which both side surfaces 1a are inclined at a central part toward a narrow top surface 1b, and its rear surface 1e forms a vertical surface or a slant surface which is approximately near the vertical surface. The first protrusion-like block 1A and the third protrusion-like block IC are fixed on the grid block 11 which is rear part of a grade cutter 19 in a fixed hearth row 12 in spaced-apart by three blocks, and at the same time the first protrusion-like block 1B is fixed in a zig-zag form between the first protrusion-like block 1A and the third protrusion-like block IC in the movable grid row 13 other than both sides.

Title: System for evaluation of sensitization degree of material by accelerated stress corrosion crack test
Inventor: OKIDO SHINOBU
IPC: G01N33/20
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To obtain a system by which the soundness and the remaining life of a structure are evaluated quickly and accurately by directly carrying out a stress corrosion test by using a sampled material inside a furnace or by using a test piece for degradation monitoring. SOLUTION: As test pieces which are used for an accelerated stress corrosion crack test, a part of an actual-machine structure, a test piece for monitoring, a remaining material after a breaking test, a structure waste material after a replacement construction and a material for evaluation, which is inserted in advance into an actual-machine structure are used. The materials are worked as various test pieces in a hot laboratory for test-piece working. The test pieces are exposed to a state loaded with a set load in a high-temperature and high-pressure environment whose water quality, electric conductivity and corrosion potential are made more severe that those of an actual-machine environment. Then, various change states at this time are monitored sequentially, and the sensitization degree of the materials is evaluated. A fundamental curve is established in advance.  The condition of the accelerated stress corrosion crack test is compared with a condition in the actual-machine environment. On the basis of the result of the accelerated stress corrosion crack test, a crack progress behavior in the actual machine environment is evaluated. Finally, an allowable dimension in a mechanical evaluation test or in a designing operation is compared with a crack progress estimation. Thereby, the remaining life of an apparatus structure is evaluated.
