Description

I Изобретение относитс к энергети- ке и может быть использовано в конструкци х газоходов котлов,I The invention relates to energy and can be used in the construction of gas ducts of boilers,

Цель изобретени - повышение надежности двухсветного экрана котла путем повышени его жесткости.,,The purpose of the invention is to increase the reliability of the double-lighted screen of the boiler by increasing its rigidity. ,,

На фиг,1 изображен двухсветный экран котла, общий вид;на фиг,2 - узел I на фиг.1; на фиг.З - вид А на фиг.2..FIG. 1 shows a double-lighted screen of the boiler, general view; FIG. 2, node I in FIG. 1; on fig.Z - view A on figure 2 ..

Двухсветный экран котла содержит р д теплообменных труб 1, установ- ленных в газоходе 2 и скрепленных между собой ребрами 3 жесткости, Верхние и нижние участки теплообмен- ных труб 1 выполнены с тройниковыми разветвлени ми 4 и 5 соответственно соединенными в каждой теплообменной трубе 1 между собой с образованием замкнутых колец, расположенных поперечно плоскости упом нутого р да и жестко скрепленных с кольцами соседних теплообменных труб 1 при помощи проставок 6.The double-lighted screen of the boiler contains a series of heat exchange pipes 1 installed in the duct 2 and stiffening ribs 3 fastened together. The upper and lower sections of the heat exchange pipes 1 are made with tee rammers 4 and 5 respectively connected in each heat exchange pipe 1 with the formation of closed rings located transverse to the plane of the said row and rigidly fixed to the rings of adjacent heat exchange tubes 1 by means of spacers 6.

Газоход 2 обрамлен фронтовым экраном 7, задним экраном 8 и боковыми экранами 9 и 10. В полости колец разветвлений 4 и 5 установлены гре- бенки 11, скрепленные с трубами экранов 7 и 8 и разветвлени ми 4 и 5.The flue duct 2 is framed by a front screen 7, a rear screen 8 and side screens 9 and 10. In the cavity of the rings of the branches 4 and 5, there are mounted the knobs 11 fastened to the pipes of the screens 7 and 8 and the branches 4 and 5.

Двухсветный экран котла работает следующим образом.The two-light boiler screen works as follows.

Claims

Heating gas flows through duct 2, where they cool, heating the medium circulating through pipes 1, branches 4 and 5, and screens 7-10. The loads from pulsations and claps in the duct 2 transmitted to the double-lined screen are perceived not only by the stiffening ribs 3, but also from the tee joints 4 and 5 with spacers 6. A decrease in the rigidity and strength of the double-lighted screen of the boiler leads to an increase in its reliability. Invention Formula

A two-light boiler screen containing a series of heat exchanging pipes fastened together with stiffening ribs, characterized in that, in order to increase reliability by increasing stiffness, the upper and lower portions of the heat exchanging pipes are made with tee branches connected together in each heat exchanging pipe. with the formation of closed rings located transverse to the plane of the said row and rigidly attached to the rings of adjacent heat exchange tubes,
