Description
(54) СЕКЦИЯ ВОЗДУХОПОДОГРЕВАТЕЛЯ(54) AIR HEATER SECTION
1one
Изобретение ОТНОСИТСЯ к энергетике и может быть использовано в паровых котлах.The invention relates to energy and can be used in steam boilers.
Известна секци воздухоподогревател , содержаща пучок теплообменных труб, закрепленных в гибких трубных дисках, одна из которых снабжена компенсатором дл компенсации температурных удлинений труб 1 .The known section of the air preheater contains a bundle of heat exchange tubes fixed in flexible tube disks, one of which is equipped with a compensator to compensate for the temperature lengthening of the tubes 1.
Недостаток указанной секции воздухоподогревател - сложность конструкции , обусловленна выполнением трубных досбк гибкими и снабжением ОДНОЙ из досок компенсатором.The disadvantage of this section of the air preheater is the complexity of the design, due to the implementation of the pipe boards flexible and the supply of ONE of the boards with a compensator.
Наиболее близкой к предлагаемой вл етс секци воздухоподогревател , содержаща закрепленный в трубных дисках пучок вертикальных теплообменных труб,.установленных р дами, плоскости которых перпендикул рны к. опорным кра м тру&ной доски, причем часть теплообменных труб вл ютс несущими, имеют диаметр и толщину больше, 1ем диаметр и толщина остальных теплообменных труб С2.An air heater section is closest to the present invention, containing a bundle of vertical heat exchanger tubes fixed in tube disks, installed in rows whose planes are perpendicular to the supporting edge of the board, and part of the heat exchanger tubes are bearing, have a diameter and thickness more, 1m diameter and thickness of the remaining heat exchange tubes C2.
Недостатком известной секции воздухоподогревател вл етс пониженна надежность из-за повьаиенных термических напр жений в местах закреплени пучка труб в тpyбны дисках.A disadvantage of the known section of the air preheater is the reduced reliability due to thermal stresses in the places where the tube bundle is fixed in the pipe discs.
обусловленных тем, что часть труб имеет диаметр и толщину больше, чем диаметр и толщина остальных теплообменных труб.due to the fact that part of the pipe has a diameter and thickness greater than the diameter and thickness of the remaining heat exchange pipes.
Разные размеры привод т к разным температурам их стенок при работе воздухонагревател и, соответственно , к разным температурным перемещени м, привод щим к разуплот10 нению конструкции.Different sizes lead to different temperatures of their walls during the operation of the air heater and, accordingly, to different temperature displacements, leading to a weakening of the structure.
Цель изобретени - повышение на; дежност секции воздухонагревател путем снижени термических напр жений в местах закреплени пучка труб The purpose of the invention is to increase by; reliability of the air heater section by reducing thermal stresses in the places where the tube bundle is fastened
15 в трубных досках.15 in tube plates.
Указанна цель достигаетс тем, что в секции воздухопрдогревател трубы в р дах на участках, расположенных со стороны опорных краев , This goal is achieved by the fact that in the section of the air heater pipe in rows in areas located on the side of the supporting edges,
20 трубной доски, соединены между собой и с трубными досками дополнительными проставками.20 tube plates are interconnected and with tube plates with additional spacers.
На фиг. 1 изображена секци воздухоподогревател ; на фиг. 2 - разрез FIG. 1 shows an air preheater section; in fig. 2 - section
25 А-А на фиг. 1.25 A-A in FIG. one.
Секци воздухоподогревател ссдержит закрепленный в трубных досках 1 и 2 пучок вертикальных теплоОбменных труб 3 и 4, установленных The air heater section will hold a bundle of vertical heat exchange pipes 3 and 4 fixed in tube plates 1 and 2
30 р дами, плоскости которых перпендикул рны к опорным кра м трубной доски 1. Трубы 3 в р дах на участках расположенных со стороны опорных краев трубной доски 1, соединены между собой и с трубными дисками 1 и 2 проставками 5. Опорные кра доски 1 установлены на каркас 6. Доски 1 и 2 выполнены пр моугольными. Наружные проставки 5 выступают до опорных краев доски 1.In 30 rows, the planes of which are perpendicular to the supporting edges of the tube plate 1. The pipes 3 in rows in the sections located on the side of the supporting edges of the tube plate 1 are connected to each other and to the tube disks 1 and 2 by spacers 5. The supporting edges of the board 1 are installed on frame 6. Boards 1 and 2 are rectangular. The outer spacers 5 protrude to the supporting edges of the board 1.
При работе воздухоподогревател весова нагрузка передаетс через трубы 4, проставки 5 и трубные доски 1 и 2 на каркас 6.During operation of the air preheater, the weight load is transmitted through the pipes 4, the spacers 5 and the tube plates 1 and 2 to the frame 6.
