Description
본 고안은 보일러에서 나오는 고온가스의 폐열을 회수하는 폐열회수 증기발생기의 내부보온재를 지지하는 보강비임 구조에 관한 것으로서, 보다 상세히는 하부비임과 하부비임을 지지하는 벅스테이의 지지대에 슬롯(slot)이 형성되고 슬롯에 볼트가 체결되는 폐열회수 증기발생기의 내부보온재를 지지하는 보강비임 구조에 관한 것이다.The present invention relates to a reinforcement beam structure for supporting the internal insulation of the waste heat recovery steam generator for recovering the waste heat of the hot gas from the boiler, in more detail the slot on the support of the buckstay supporting the lower beam and the lower beam It relates to a reinforcement beam structure for supporting the internal insulation of the waste heat recovery steam generator is formed and the bolt is fastened to the slot.
도 1에 도시된 폐열회수 증기발생기는 가스터빈에서 배출되는 고온가스의 폐열을 회수하여 재사용하므로서 보일러의 열효율을 높이기 위한 장치로서, 가스터빈에서 나오는 고온가스가 다수의 고압 증발기(HP EVA), 고압 절탄기(HP ECO), 저압 증발기(LP EVA) 및 저압 절탄기(LP ECO) 등을 순서대로 거치면서 물과 열교환되므로서 버려지는 고온가스의 폐열을 회수하는 장치이다.The waste heat recovery steam generator shown in FIG. 1 is a device for improving the thermal efficiency of a boiler by recovering and reusing waste heat of hot gas discharged from a gas turbine, and a plurality of high pressure evaporators (HP EVA) It is a device that recovers the waste heat of the hot gas that is discarded by heat exchange with water while passing through an economizer (HP ECO), a low pressure evaporator (LP EVA) and a low pressure economizer (LP ECO).
도 2에 도시된 바와같이, 폐열회수 증기발생기(1)는 다수의 전열관(3)과, 내부보온재를 지지하는 케이싱(5)과, 상기 케이싱(5)을 지지하는 상부 비임(7), 벅스테이(buckstay : 9) 및 하부 비임(11)으로 구성된다.As shown in FIG. 2, the waste heat recovery steam generator 1 includes a plurality of heat transfer tubes 3, a casing 5 for supporting the inner heat insulating material, an upper beam 7 for supporting the casing 5, and a bucks. It consists of a buckstay 9 and a lower beam 11.
상기 폐열회수 증기발생기의 내부보온재를 지지하는 보강비임 구조는 상부비임(7)에 고정된 행거로드(8) 및 하부비임(11)이 전열관(3)을 지지하고, 케이싱(5)과 하부비임(11)이 서로 용접되며, 도 3에 도시된 바와같이 하부비임(11)의 양단이 벅스테이(9)에 용접된다. 또한, 벅스테이(9)는 폐열회수 시스템이 작동할 때 열에 의해 하부비임(11)이 팽창하기 때문에 이를 견딜 수 있을 정도로 그 크기가 충분히 커야 한다.The reinforcement beam structure for supporting the inner heat insulating material of the waste heat recovery steam generator has a hanger rod 8 and a lower beam 11 fixed to the upper beam 7 to support the heat transfer pipe 3, and the casing 5 and the lower beam. 11 is welded to each other, and both ends of the lower beam 11 are welded to the buckstay 9 as shown in FIG. In addition, the buckstay 9 should be large enough to withstand this because the lower beam 11 expands due to heat when the waste heat recovery system is operated.
그러나, 상기와 같은 종래의 폐열회수 증기발생기의 내부보온재를 지지하는 보강비임 구조는 열에 의해 하부비임이 팽창하는 것에 견디기 위해 벅스테이가 크게 제작되고 또한 벅스테이를 지지하는 앵커볼트(anchor bolt)의 수가 증가하는 등 기초공사량이 증가하는 문제점이 있었다.However, the reinforcement beam structure for supporting the inner heat insulating material of the conventional waste heat recovery steam generator as described above, the buckstay is made large in order to withstand the expansion of the lower beam by heat, and also of the anchor bolt (anchor bolt) supporting the buckstay There was a problem in that the amount of foundation work, such as the increase in number.
따라서, 본 고안의 목적은 폐열회수 증기발생기의 내부보온재를 확실하게 지지하면서 주칼럼인 벅스테이의 크기가 커지는 것을 방지할 수 있는 폐열회수 시스템의 내부보온재를 지지하는 보강비임 구조를 제공하는데 있다.Accordingly, an object of the present invention is to provide a reinforcing beam structure that supports the internal heat insulating material of the waste heat recovery system that can prevent the size of the buckstay, which is the main column, from steadily supporting the internal heat insulating material of the waste heat recovery steam generator.
상기와 같은 목적을 달성하기 위한 본 고안에 따른 폐열회수 시스템의 내부보온재를 지지하는 보강비임 구조의 일예는 벅스테이 하단 내측에 부착된 지지 부재에 복수의 슬롯이 형성되고, 하부 수평부재의 단부에 지지 부재의 슬롯에 대응되게 복수의 슬롯이 형성되며, 상기 지지 부재의 슬롯들과 하부 수평부재의 슬롯들이 각각 일치되고, 상기와 같이 일치된 슬롯들을 통해 체결수단이 체결되어 지지부재에 하부 수평부재가 고정되며, 상기 하부 수평부재는 벅스테이에서 하부 수평부재의 열팽창량보다 약간 더 크게 이격되는 것을 특징으로 한다.An example of the reinforcing beam structure for supporting the inner heat insulating material of the waste heat recovery system according to the present invention for achieving the above object is a plurality of slots are formed in the support member attached to the bottom of the buckstay, the end of the lower horizontal member A plurality of slots are formed to correspond to the slots of the support member, the slots of the support member and the slots of the lower horizontal member are matched, respectively, the fastening means are fastened through the matched slots as described above to the lower horizontal member Is fixed, the lower horizontal member is characterized in that the buckstay spaced slightly larger than the thermal expansion amount of the lower horizontal member.

도 4를 참조하면, 본 고안에 따른 보강비임 구조는 벅스테이의 지지대에 하부비임 양단이 볼트에 의해 체결되나, 그 체결구조가 같아 도 4에는 하부비임의 일단만이 도시되어 있다.4, in the reinforcement beam structure according to the present invention, both ends of the lower beam are fastened by bolts to the support of the buckstay, but the fastening structure is the same, and only one end of the lower beam is shown in FIG.
본 고안에 따른 폐열회수 증기발생기의 내부보온재를 지지하는 보강비임 구조는 벅스테이(21) 하단 내측에 부착된 지지대(23)에 슬롯(25, 27)이 형성되고, H 형강인 하부비임(29)의 단부에 슬롯(31, 33)이 형성되며, 상기 지지대(23)의 슬롯(25, 27)과 하부비임(29)의 슬롯(31, 33)이 각각 일치되고, 상기 슬롯(25,31 및 27, 33)을 통해 볼트(35, 37)가 체결되어 지지대(23)에 하부비임(29)이 고정된다.The reinforcement beam structure for supporting the inner heat insulating material of the waste heat recovery steam generator according to the present invention is formed with slots 25 and 27 in the support 23 attached to the bottom of the buckstay 21, and the lower beam 29 is H-shaped steel. Slots 31 and 33 are formed at the ends of the slots, slots 25 and 27 of the support 23 and slots 31 and 33 of the lower beam 29 are respectively matched. And the bolts 35 and 37 are fastened through the 27 and 33 to fix the lower beam 29 to the support 23.
상기 하부비임(29)은 벅스테이(21)에서 일정간격(d) 이격되며, 상기 간격(d)은 하부비임(29)의 열팽창량보다 약간 더 크다.The lower beam 29 is spaced a predetermined distance d from the buckstay 21, the interval d is slightly larger than the thermal expansion amount of the lower beam (29).
상기와 같은 구성에 의해 본 고안에 따른 보강비임 구조는 보일러(도시하지 않음)가 가동되어 폐열회수 증기발생기로 고온의 가스가 유입되면, 지지대(23)에 지지된 하부비임(29)이 슬롯(25,31 및 27, 33)의 장방향으로 열팽창하게 된다. 그러나, 하부비임(29)의 열팽창량은 벅스테이(21)에서 이격된 간격(d)보다 작기 때문에 하부비임(29)의 열팽창에 의해 벅스테이(21)가 압력을 받지 않는다.The reinforcement beam structure according to the present invention by the configuration as described above is operated by the boiler (not shown) when the hot gas flows into the waste heat recovery steam generator, the lower beam 29 supported on the support 23 is a slot ( 25, 31 and 27, 33 are thermally expanded in the longitudinal direction. However, since the amount of thermal expansion of the lower beam 29 is smaller than the distance d spaced apart from the buckstay 21, the buckstay 21 is not pressurized by the thermal expansion of the lower beam 29.
본 고안에 따른 폐열회수 증기발생기의 내부보온재를 지지하는 보강비임 구조는 하부비임의 열팽창에 의해 벅스테이가 압력을 받지 않기 때문에 벅스테이의 반력을 제로화할 수 있으므로서 벅스테이 등의 중량 및 크기를 줄일 수 있어 기초공사가 용이해지는 효과가 있다.The reinforcement beam structure for supporting the inner heat insulating material of the waste heat recovery steam generator according to the present invention can reduce the reaction force of the buckstay because the buckstay is not pressurized by the thermal expansion of the lower beam, thereby reducing the weight and size of the buckstay. Since it can be reduced, there is an effect of facilitating foundation work.
