Description
(54) ШИРМОВАЯ ITOBEFXHOCTb НАГРЕВА(54) WIRELESS ITOBEFXHOCTb HEATING
Изобретение относитс к котлостро ению и может быть использовано в кот лах с ширмовыми пароперегревател ми. Наиболее близким к изобретению техническим решением вл етс ширмова поверхность нагрева, содержаща коллекторы дл подвода и отвода нагреваемой среды с теплообменными трубами, соединенными полухомутами, жестко скрепленными с частью труб С Недостатком такой конструкции вл етс низка эффективность охлаждени полухомутов, что уменьшает надежность поверхности нагрева в работе . Цель изобретени - повышение надежности путем интенсификации охлаждени полухомутов. Поставленна цель достигаетс тем что полухомуты скреплены с трубами через одну и вьшолнены переменной ши рины, убывающей по мере удалени от места креплени их к трубам. При это отношение максимальной пшрины полухомута к минимальной составл ет 1,2-2,0. На фиг . 1 показана ширмова поверхность нагрева , общий вид; на фиг. 2 узел J на фиг. 1; на фиг. 3 - разрез А-А на фиг. 1. Предлагаема ширмова поверхность нагрева может быть выполнена, в частности , из теплообменных труб, подключенных к средам с разной температурой и расположенных в одной плоскости в чередующемс пор дке. Поверхность нагрева содержит коллекторы 1, 2 дл подвода и коллекторы 3, 4 дл отвода нагреваемых сред, соответственно большей и меньшей температуры .Коллекторы 1 и 3 соединены между собой теплообменными трубами 5, а коллекторы 2 и 4 соединены трубами 6. С трубами 6 жестко скреплены полухомуты 7, охватывающие трубы 5. Полухомуты 7 выполнены переменной ширины, убывгиощей по мере удалени The invention relates to a boiler and can be used in boilers with screen superheaters. The closest technical solution to the invention is a screen heating surface containing collectors for supplying and discharging the heated medium with heat exchange pipes connected with half-sleeves rigidly attached to a part of the pipes. . The purpose of the invention is to increase reliability by intensifying the cooling of half-hobs. The goal is achieved by the fact that the half-sleeves are fastened to the pipes through one and are filled with variable widths, decreasing as they move away from the place of their attachment to the pipes. With this ratio, the maximum width of the half-joint to the minimum is 1.2-2.0. FIG. 1 shows a screen heating surface, a general view; in fig. 2, node J in FIG. one; in fig. 3 shows section A-A in FIG. 1. The proposed screen heating surface can be made, in particular, of heat exchange tubes connected to media with different temperatures and located in the same plane in alternate order. The heating surface contains collectors 1, 2 for the inlet and collectors 3, 4 for removal of heated media, respectively, of higher and lower temperatures. The collectors 1 and 3 are interconnected by heat exchange tubes 5, and the collectors 2 and 4 are connected by tubes 6. half-sleeves 7, covering pipes 5. Half-sleeves 7 are made of variable width, decreasing as they move
