摘要： PROBLEM TO BE SOLVED: To eliminate the need for field assembling of instruments and a piping system disposed around a temperature reducer mounted on a waste heat recovery boiler by simplifying these instruments and piping system. SOLUTION: In a waste heat recovery boiler where a temperature reducer 27 for an overheater is provided at least on one of the overheater and a reheater, the temperature reducer 27 is disposed substantially vertically along the outside of a side wall of a waste heat recovery boiler body 33, to an inlet and an outlet of which body there is connected a communication piping 32 of the overheater and the reheater, and a temperature reduction adjusting valve 29 of the temperature reducer 27 is provided on a floor 36. The temperature reducer 27 is disposed along the side wall of the waste heat recovery boiler body 33 whereby the communication piping 32 is simplified, and hence instruments and pipings around the temperature reducer 27 can be laid in a module to result in economization. Further, since the temperature reducer 27 is vertically disposed, temperature reduced water sprayed from a spray nozzle 35 flows from an upper side to a lower side (or from a lower side to the upper side) so that it can be directed to flow uniformly in the pipings for ensurance of high temperature reduction effect.

摘要： PURPOSE: To cope with the increase of the size of a vertical type waste heat recovery boiler with a built-in denitrating device by only one tower. CONSTITUTION: The load of a catalyst support frame 27 on which a denitrating catalyst is placed is transmitted to a catalyst suspension frame 43 through a height adjusting metal fitting 36 by a suspension metal fitting 38. The load transmitted to the catalyst suspension frame 43 is transmitted to an further upper part pipe group support 25 by suspension metal fitting 24 arranged at a suspension distance matched with a pipe group support distance. An orderly transmitted load is finally supported by a main support frame through an internal device support large beam 31 arranged at a lowest temperature part. Further, a bi-directional expansion is located between a casing and the catalyst support frame 27. When the size of a vertical waste heat recovery boiler wherein a long span integral structure is provided is increased in such a way that a denitriding catalyst frame on which a denitrating catalyst is carried is suspended and supported at multipoint, coping with the size increase only by one tower. By using the bi-directional expansion, the difference in elongation in a biaxial direction due to thermal expansion is absorbed and short pass of exhaust gas can be prevented.

摘要： PURPOSE:To provide an aligning structure for a boiler furnace wall having a superior durability in which the concentration of stress at an aligning corner between the furnace wall and a sub-side wall. CONSTITUTION:A boiler furnace wall is so constructed that the furnace wall, a sub-side wall and a rear part heat transfer wall are constructed by walls in which pipes 14, 15 and membrane bars 13 are welded to each other to have an integral structure. A bottom wall 5 and a side wall 6 are connected to a side wall 4 of the furnace wall and at the same time the side wall of the rear heat transfer wall and a front wall are connected to an outlet side of the sub- side wall. One or a plurality of pipes 17 positioned most nearly to the side wall 6 of the sub-side wall in many pipes constituting the side wall 4 of the furnace wall are uniformly bent along the bottom wall 5 of the sub-side wall and then arranged within the side wall 6 of the sub-side wall.

摘要： PURPOSE:To reduce a concentration of a thermal stress by a method wherein a first slit is arranged at a first connecting part where a furnace wall and a sub-side wall crossed to each other in a three-dimensional manner and further a second slit is arranged at a connecting part where the sub-side wall and a rear heat transmitting wall are crossed to each other in a three-dimensional manner. CONSTITUTION:A first connecting part 8a is arranged at a corner part where a side wall 11 of a furnace wall 1, a bottom wall 4 of a sub-side wall 2 and a side wall 5 are connected to each other in a three-dimensional manner. In turn, a second connecting part 8b is arranged at a corner part where the bottom wall 4 of the sub-side wall 2, the side wall 5 and a front wall 6 of a rear part heat transmitting wall 3 are connected to each other in a three-dimensional manner. A slit 14-1 having a predetermined length is formed in a direction where the sub-side wall bottom wall 4 extends from the connecting part 8a while this connecting part 8a being applied as a starting point. A slit 26-1 having a predetermined length is formed in an upward direction where a side wall 5 of the sub-side wall 2 extends from the connecting part 8b while the connecting part 8b being applied as a base point.
