Description
본 고안은 배열회수보일러간의 급수펌프연동화구조에 관한 것으로, 더욱 상세하게는 복수개의 배열회수보일러간의 급수펌프를 공유배관을 통해 연결시켜 유사시 다른쪽 급수펌프를 이용할 수 있도록 한 것이다.The present invention relates to a feed water pump interlocking structure between the heat recovery boilers, and more particularly, to connect the water supply pumps between the plurality of heat recovery boilers through a shared pipe to use the other feed water pump in case of emergency.
일반적으로, 복합화력은 가스터빈을 운전하고 1차 발전을 한 후, 배출된 620 ℃ 정도의 고온의 배기가스를 재열회수보일러에서 회수, 이 열을 이용하여 증기터빈발전에 적합한 증기를 생산 발전하여 열효율을 향상시키는 발전방식이다.In general, the combined cycle power is generated by operating the gas turbine after the first power generation, and recovering the discharged high-temperature exhaust gas of about 620 ℃ from the reheat recovery boiler, and using this heat to produce steam suitable for steam turbine power generation. It is a power generation method to improve thermal efficiency.
이러한 복합화력발전소는 2대의 배열회수보일러(Heat Recovery Steam Generator, 이하 "HRSG"라 약칭함)가 한조를 이루는 개념으로 운용되고 있으며, 서로 같은 건물내에 또는 나란히 설치되며, 1대만 운전하는 경우는 드물고 동시에 2대를 운전한다.The combined cycle power plant is operated under the concept of two heat recovery steam generators (hereinafter abbreviated as "HRSG"), which are installed in the same building or side by side, and rarely operate only one unit. Drive two at the same time.
그런데, 첨부된 예시도면 도 1에 도시된 바와 같이, 2대를 이루는 제 1,2 HRSG(10)(20)에 각각 복수급수펌프(30)(condensate pump)(30)로부터 분기되어 각각의 복수프리히터(condensate pre-heater)(11)(21) 및 저압드럼부(12)(22)를 거쳐서 3대의 급수펌프(13)(23)를 통해 각각 고압드럼부(14)(24) 및 중압드럼부(15)(25)로 유체가 흐르도록 되어 있다.However, as shown in the accompanying drawings in FIG. 1, the plurality of first and second HRSGs 10 and 20 branched from the condensate pump 30 and the plurality of condensate pumps 30 respectively, respectively High pressure drums 14, 24 and medium pressure through three feed pumps 13, 23 via condensate pre-heater 11, 21 and low pressure drums 12, 22, respectively. The fluid flows to the drums 15 and 25.
여기서, 종래에는 제 1,2HRSG(10)(20)에 동일용량의 급수펌프(13)(23)가 독립되게 3대씩 연결되어 있어 1대의 급수펌프의 운전시, 나머지 1대 또는 2대의 펌프는 예비펌프로 대기상태로 있게되어 비경제적인 측면이 있다.Here, conventionally, three first and second HRSGs 10 and 20 are independently connected to three water pumps 13 and 23 of the same capacity. There is an uneconomical aspect of being in standby with a reserve pump.
또한, 각 HRSG별 3대의 급수펌프(13)(23)의 흡입측과 토출측의 배관과 조절용 밸브류 등을 복잡하게 연결구성, 설치하여야 되므로, 자재비가 상승하는 요인이되고, 설치공간을 많이 차지하게 되어 HRSG건물도 비례해서 커져야 하는 문제점이 있었다.In addition, since the piping and control valves and the like on the suction side and the discharge side of the three feedwater pumps 13 and 23 for each HRSG must be complicatedly connected and installed, the material cost increases and occupies a lot of installation space. There was a problem that HRSG buildings also need to grow in proportion.
또한, 동일용량의 예비급수펌프 1대 또는 2대씩에 대한 보수유지를 위한 장비가 추가설치되어야 하므로, 매우 비경제적인 것이다.In addition, it is very uneconomical because equipment for maintenance of one or two spare water feed pumps of the same capacity must be additionally installed.
이에 본 고안은 상기와 같은 종래의 제반 문제점을 해결하기 위한 것으로, 경제적이면서 적은 공간을 차지하도록 한 배열회수보일러의 급수펌프 설치구조를 제공함에 그 목적이 있다.The present invention is to solve the above-mentioned conventional problems, it is an object of the present invention to provide a water supply pump installation structure of the heat recovery boiler to take up less space and economical.
도 1은 종래기술에 따른 HRSG의 연결구조를 도시한 계통도1 is a schematic diagram illustrating a connection structure of an HRSG according to the related art.
도 2는 본 고안에 따른 HRSG의 연결구조를 도시한 계통도Figure 2 is a schematic diagram showing a connection structure of the HRSG according to the present invention
상기와 같은 목적을 달성하기 위한 본 고안은 제 1,2 HRSG에 각각 급수펌프1대를 설치하고, 1대의 급수펌프 정지시에는 나머지 1대의 급수펌프로 제 1,2 HRSG를 담당할 수 있도록 각 급수펌프의 흡입 및 토출배관을 상호연결하여 공유되도록 한 것을 기술적 특징으로 한다.The present invention for achieving the above object is to install one water supply pump in each of the first and second HRSG, and when one water supply pump is stopped, each of the first and second HRSG to be in charge of the first and second HRSG It is a technical feature that the interconnection of the suction and discharge pipes of the feed water pump is shared.
이하 본 고안의 바람직한 실시예를 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 따른 설치구조를 나타낸 도면으로서, 도시된 바와 같이, 복수급수펌프(40)로부터 분기되어 2대의 제 1,2HRSG(50)(60)로 나뉘는데, 복수프리히터(51)(61)를 거쳐 각각의 저압드럼부(52)(62)가 구비되고, 이 저압드럼부(52)(62)에 각각 1대씩의 급수펌프(53)(63)가 갖추어져 고압드럼부(54)(64) 및 중압드럼부(55)(65)로 유체가 흐르도록 연결되어 있다.2 is a view showing the installation structure according to the present invention, as shown, branched from the plurality of water supply pump 40 divided into two first and second HRSG (50) 60, a plurality of pre-heater 51 ( Each of the low pressure drum parts 52 and 62 is provided via a 61, and each of the low pressure drum parts 52 and 62 is provided with one feed pump 53 and 63, respectively. The fluid is connected to the 64 and the medium pressure drums 55 and 65 so as to flow the fluid.
여기서, 상기 복수프리히터(51)(61)로부터 나오는 배관라인과 상기 저압드럼부(52)(62)간에는 급수의 공유가 가능하도록 하는 공유배관(70)이 연결되어 있다.Here, a shared pipe 70 is connected between the pipe line coming out of the plurality of preheaters 51 and 61 and the low pressure drum parts 52 and 62 so as to share water supply.
또한, 상기 급수펌프(53)(63)으로부터 상기 고압 및 중압드럼부(54)(64)(55)(65)로 연결되는 배관라인에도 각각 공유배관(72)(74)이 연결되어 있다.In addition, shared pipes 72 and 74 are also connected to the pipe lines connected to the high pressure and medium pressure drums 54, 64, 55 and 65 from the feed water pumps 53 and 63, respectively.
이와 같이 구성된 본 고안은 제 1,2HRSG(50)(60)의 운전중 어느 한쪽이 고장인 경우, 나머지 한쪽에서 공유배관을 통해 급수펌프를 가동하여 일정량의 급수를 보내어 반드시 해당 HRSG가 정지하지 않아도 된다.The present invention configured as described above, when any one of the operation of the first and second HRSG (50, 60) is broken, the other side by operating the water supply pump through a shared pipe to send a certain amount of water supply does not necessarily stop the HRSG do.
이와 같이 본 고안에 의하면, 공유배관을 통해 2대의 HRSG가 서로 연통되게연결되어 있고, 별도의 밸브조작이나 장치없이 유량이 분배되므로, 설비의 안정성 및 자재비 절감을 이룰 수 있는 효과가 있다.As such, according to the present invention, two HRSGs are connected in communication with each other through a shared pipe, and the flow rate is distributed without a separate valve operation or device, thereby achieving stability of the facility and reducing material costs.
