摘要： Suspended superheaters (52 and 53) alone are provided in the outlet of a furnace. The heat transfer areas of these superheaters are determined so that the temperature of exhaust gas in the rear flow thereof may be 1000-1100 DEG C under the maximum load of a boiler. The passages of the exhaust gas in the rear flow of the superheaters (52 and 53) are divided into subpassages along the flow of the exhaust gas and a damper for regulating the flow rate of the exhaust gas flowing through each subpassage is provided at an outlet of each of the subpassages. A horizontal reheater (41) is provided for the subpassages. Since the temperature difference between the temperature (1000-1100 DEG C) of the exhaust gas flowing around the reheater (41) and the temperature of steam flowing through the reheater (41) is large, a highly effective heat exchange can be conducted for even a small heat transfer area. Accordingly, an increase in the heat transfer area of the reheater (41), that is, in the size of the whole, can be suppressed.

摘要： A furnace wall 1 comprises: a furnace wall bottom part A composed of furnace wall tubes 2a having upward-spiraled fluid passages; a nose part C which has nose wall tubes 5a disposed in a middle part of a furnace rear wall B adjoining the furnace wall bottom part A; and a screen part D having screen tubes 7, wherein the terminal parts of the furnace wall tubes 2a are located lower than the nose part C. Consequently, the drain generated in the nose wall tubes 5a while the operation of the boiler is suspended can naturally fall inside the furnace wall tubes 2a located lower than the nose part C, and in a case where the header 6 is connected with the terminal parts of the furnace wall tubes 2a, the drain generated in the nose wall tubes 5a can naturally fall inside the header 6. In addition, the furnace wall tubes 2b (2b1, 2b2) which extend upright from the terminal parts of the furnace wall tubes 2a can be provided to connect parts 2b1 of the furnace wall tubes 2b directly with the header 6, to connect the header 6 with the nose wall tubes 5a via vertical tubes 5e1 and 5e2; and to connect other parts 2b2 of the furnace wall tubes 2b directly with the screen tubes 7, thereby integrating the vertical furnace wall tubes 2b (2b1, 2b2), the vertical tubes 5e, and 5e2, and the screen tubes 7 by being welded via membrane bars 3. This results in the furnace wall structure not requiring reinforcing supports for supporting the weight of the furnace wall bottom part A.

摘要： SE INSTALAN SOBRECALENTADORES SUSPENDIDOS (52 Y 53) EN LA SALIDA DE UN HORNO. LAS AREAS DE TRANSFERENCIA DE CALOR DE ESTOS SOBRECALENTADORES SE DETERMINAN DE TAL MODO QUE LA TEMPERATURA DEL GAS DE ESCAPE EN EL FLUJO TRASERO DE LOS MISMOS PUEDA SER DE 1.000 A 1.100 (GRADOS) C EN CONDICIONES DE CARGA MAXIMA DE UNA CALDERA. LOS CONDUCTOS DE PASO DE GAS DE ESCAPE EN EL FLUJO TRASERO DE LOS SOBRECALENTADORES (52 Y 53) SE DIVIDEN EN SUBCONDUCTOS A LO LARGO DEL FLUJO DE GAS DE ESCAPE Y SE INSTALA UN REGULADOR PARA REGULAR EL CAUDAL DE GAS DE ESCAPE QUE FLUYE POR CADA SUBCONDUCTO EN UNA SALIDA DE CADA UNO DE LOS SUBCONDUCTOS. SE INSTALA UN RECALENTADOR HORIZONTAL (41) PARA LOS SUBCONDUCTOS. COMO LA DIFERENCIA TERMICA ENTRE LA TEMPERATURA (1.000-1.100 (GRADOS) C) DEL GAS QUE ESCAPE QUE FLUYE ALREDEDOR DEL RECALENTADOR (41) Y LA TEMPERATURA DEL VAPOR QUE FLUYE POR EL RECALENTADOR (41) ES GRANDE, SE PUEDE REALIZAR UN INTERCAMBIO DE CALOR ALTAMENTE EFECTIVO INCLUSO PARA UNA PEQUEÑA AREA DE TRANSFERENCIA. CORRESPONDIENTEMENTE, PUEDE SUPRIMIRSE EL AUMENTO DEL AREA DE TRANSFERENCIA DE CALOR DEL RECALENTADOR (41), ES DECIR, DEL TAMAÑO DEL CONJUNTO.

摘要： Suspended superheaters (52 and 53) alone are provided in the outlet of a furnace. The heat transfer areas of these superheaters are determined so that the temperature of exhaust gas in the rear flow thereof may be 1000-1100 DEG C under the maximum load of a boiler. The passages of the exhaust gas in the rear flow of the superheaters (52 and 53) are divided into subpassages along the flow of the exhaust gas and a damper for regulating the flow rate of the exhaust gas flowing through each subpassage is provided at an outlet of each of the subpassages. A horizontal reheater (41) is provided for the subpassages. Since the temperature difference between the temperature (1000-1100 DEG C) of the exhaust gas flowing around the reheater (41) and the temperature of steam flowing through the reheater (41) is large, a highly effective heat exchange can be conducted for even a small heat transfer area. Accordingly, an increase in the heat transfer area of the reheater (41), that is, in the size of the whole, can be suppressed.
