摘要： PURPOSE:To increase the flow speed of feed water in the area of an economizer and improve heat transfer performance by arranging feed water flow speed increasing members between a plurality of heat transfer tubes in the area of the economizer. CONSTITUTION:Feed water flow speed increasing members 20 for increasing the flow speed of feed water 14 flowing through the area 9 of an economizer are arranged between heat transfer tubes 6 in the area 9 of the economizer. The feed water 14 flows through an annular passage 24, defined between the outer surfaces of respective heat transfer tubes 6 and the inner surface of a sleeve 21, as shown by an arrow sign 23 in a diagram and passes through the area 9 of the economizer to enter into boiling area. The flow speed of the feed water in the area of the economizer is increased by providing the flow speed increasing members between the heat transfer tubes in the area of the economizer in such a manner and, therefore, a heat transfer rate in secondary side is changed and a heat passing coefficient is increased whereby heat transfer performance may be improved.

摘要： PURPOSE:To provide a titled device which forms heat transmitting rib parts without distortion of a pipe material by moving a tapered mandrel to press the heel blocks in the bore of the pipe material thereto, pressing the projecting members each having a brazing material on the contact part to the outside circumfference of the pipe material by means of inductors and brazing the members by the high frequencies generated by the coils built in the inductors. CONSTITUTION:Split heel blocks 4 are put into the bore of a pipe material 1 and a tapered mandrel 3 is moved to press said blocks to the bore surface. Rib members 2 each having a brazing material on the contact surface are put into the recesses of split type inductors 10, 11, 12, 13 and are fitted to the outside circumferential surface of the material 1. The members 2 are pressed to the outside circumferential surface of the material 1 by means of a fastening ring 20. Electricity is conducted to the water- cooled high-frequency coils 15-18 in the inductors 10-13 to heat the members 2 and to braze the same to the outside circumferential surface of the material 1. The heat transmitting rib parts 2 of the material 1 are formed by such procedure. The pressing of the blocks 4 and the inductors 10-13 are balanced and there are practically no internal and external distortions of the material 1 owing to the formation of the rib parts 2. The material 1 is thus made into the good heat transmitting pipe.
