Title: Lining pipe and its manufacture
Inventor: HOSOSUNA SHIGEMI
IPC: B21D39/04
Filed: 1985-08-09
Abstract: PURPOSE:To prevent a trouble from being generated due to a thermal stress by providing a spiral groove on the inner surface of a main pipe, bringing into a lining blank pipe contact with to the inner surface of the main pipe, and absorbing a difference of coefficients of thermal expansion of the main pipe and the lining pipe. CONSTITUTION:A spiral groove 11' is formed on the inner surface of a main pipe 11 by a roller working, etc. Subsequently, a lining blank pipe 12 of a thin wall made of Ti, Zr, etc. is inserted into the main pipe which has formed the groove 11' on the inner surface. To this lining blank pipe 12, a stress exceeding a yield point of the thin wall lining blank pipe 12 is applied by operating an explosion, a hydraulic pressure, etc., and a lining pipe 13 is brought into contact with each other and formed on the inner surface of the main pipe 11 and in the groove 11'. Since the inner surface of the lining pipe 13 is brought to a groove working and formed in a shape of a waveform, a thermal expansion difference of a lining material such as Ti, Zr, etc. of a corrosion resisting material, and a base material is absorbed. In this way, a thermal stress load to a lining pipe end part is reduced, and a lining pipe of a long service life is obtained.

Abstract: PROBLEM TO BE SOLVED: To male it possible to cope with various kinds of refuse incineration and improve the combustion efficiency of the whole incinerator by using a fan-shaped fire grate for a dry stoker, and a step type fire grate for a combustion stoker and a post combustion stoker. SOLUTION: The refuse charged from a hopper 4 is fed to a dry stoker 5 by a refuse feeding device 8. In the dry stoker 5, each row of fan-shaped fire grates 18 are turned at an angle of elevation from about 60 to 70 deg. from the horizontal line so that the refuse may be erected. While turning over, the fire grates break up the lumps of refuse by agitating and move the refuse from the upper stage to the lower stage. The combustion stoker 6 feeds the refuse from the dry stoker 5 to the post combustion stoker 7 in a bonfire state by means of a step type fire grate 23 which agitates the refuse up-and-down, and back-and-forth direction by an offset between a stationary fire grate 24 and a movable fire grate 25 produced by a reciprocating motion of the movable fire grate 25.  While agitating the refuse in a bonfire state in up-and-down and back-and-forth direction like the combustion stoker 6, the post combustion stoker 7 feeds the refuse to an ash receiving flap 9 by feeding forcibly a combustion air from a fan device, thereby producing the post combustion with the forced combustion air.
