Description

В паровых жаротрубных котлах иногда наблюдаютс  трещины, по вление которых может быть объ снено температурными напр жени ми, вызываемыми неравномерным нагреванием различных частей котла. Во избежание этого предлагаетс  применить в жаротрубном паровом котле свободную, не скрепленную жестко с передним днищем барабана жаровую трубу, снабженную в месте прохода через переднее днище сальнико;вым уплотнением.In steam fire-tube boilers, cracks are sometimes observed, the occurrence of which can be explained by temperature stresses caused by uneven heating of different parts of the boiler. In order to avoid this, it is proposed to use in a fire-tube steam boiler a free, not rigidly bonded to the front bottom of the drum, a fire tube provided in place of passage through the front bottom of the packing;

На чертеже фиг. 1 изображает продольный разрез жаротрубного парового котла и фиг. 2-продольный разрез сальника.In FIG. 1 shows a longitudinal section of a fire-tube steam boiler; and FIG. 2 is a longitudinal section of the gland.

Жарова  труба 7 (фиг. 1), свободно проход ща  сквозь переднее днище 2 барабана, не имеет жесткого с ним соеинени  и в месте прохода снабжена сальниковым уплотнением 3. Задн   часть жаровой трубы поставлена на роики 4, а топочные св зи котла устраены . Описанное устройство имеет цельюThe heat pipe 7 (Fig. 1), freely passing through the front plate 2 of the drum, does not have a hard connection with it and is equipped with an omental seal 3 at the passage point. The rear part of the fire tube is placed on the roiki 4, and the furnace connections of the boiler are arranged. The described device is intended

обеспечить возможность беспреп тственного удлинени  жаровой трубы при возникновении значительных температурных разностей между стенками трубы и листами барабана и тем устранить температурные напр жени  в металле трубы и барабана.to ensure the possibility of unhindered elongation of the flame tube when significant temperature differences occur between the pipe walls and the drum sheets and, thus, to eliminate the temperature stresses in the metal of the tube and drum.

Предмет изобретени .The subject matter of the invention.

Жаротрубный паровой котел, отличающийс  применением свободной не скрепленной жестким соединением с передним днищем 2 барабана жаровой трубы 7 (фиг. 1), снабженной в месте прохода через переднее днище барабана сальниковым уплотнением 3 (фиг. 1 и 2) в цел х обеспечени  возможности беспреп тственного удлинени  жаровой трубы при возникновении значительных температурных разностей между стенками жаровой трубы и листами барабана , с целью устранени  температурных напр жений в металле трубы и барабана .The fire-tube steam boiler, characterized by the use of a loose, non-bonded rigid connection to the front bottom 2 of the reel of the flame tube 7 (Fig. 1), provided at the passage point through the front bottom of the drum with an omental seal 3 (Fig. 1 and 2) in order to ensure unhindered elongation of the flame tube when significant temperature differences occur between the walls of the flame tube and the drum sheets, in order to eliminate thermal stresses in the metal of the tube and drum.
