Description
본 발명은 화력발전소의 냉각탑 견적을 산출하는 방법에 관한 것으로, 특히 냉각탑 설계 조건 별 가격에 영향을 미치는 요인들을 데이터화 하여 각 조건에 의한 사이징 팩터(Sizing Factor)를 고려해 냉각탑의 견적을 산출하는 방법에 관한 것이다.The present invention relates to a method for calculating a cooling tower estimate of a thermal power plant, and in particular, a method for calculating the estimation of a cooling tower in consideration of a sizing factor of each condition by data-factoring factors affecting the price for each cooling tower design condition. It is about.
일반적으로, 냉각탑은 발전소에 냉각수 공급이 원활하지 못한 지역에 사용되는 폐회로 냉각수 시스템(Closed Circuit Cooling Water System)을 구성하는 요소로서, 터빈의 고출력을 얻기 위해 증기를 응축하는데 사용되는 응축기(Condenser)를 통해 상승한 냉각수를 대기를 통해 다시 냉각시키는 설비이다.Generally, the cooling tower is a component of the closed circuit cooling water system used in areas where the cooling water is not supplied to the power plant. The cooling tower is a condenser used to condense the steam to obtain the high output of the turbine. It is a facility that cools the rising coolant through the atmosphere again.
이러한 냉각탑 설계 시, 종래에는 냉각탑의 설계 데이터를 토대로 업체에서 제출하는 견적서를 접수해야만 견적을 예측할 수 있었다. 따라서, 견적서 접수 전에는 업체에서 제시하는 금액을 예상할 수 없어 업체에 최적의 금액을 유도할 수 없는 문제점이 있었다.In the design of such a cooling tower, in the past, the quotation could be predicted only by receiving a quotation submitted by a company based on the design data of the cooling tower. Therefore, there is a problem in that it is not possible to predict the amount of money presented by the company before the quotation is received, so that the optimal amount cannot be derived from the company.
본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로 그 목적은, 촉박한 견적 소요기간이 요청되어 업체로부터 견적가를 접수할 수 없는 경우나 기존의 수행 프로젝트가 있는 경우에 상대 비교를 통해 업체 견적가의 적정성을 판단하고, 다양한 설계 조건 중 최적의 설계 조건을 결정하는데 가이드를 제공하는데 있다.The present invention has been made to solve the problems described above, the purpose of which is to request a quote price from the company is not able to receive a quote price from the company, or if there is an existing project to carry out the comparison of the company quote price To determine adequacy and provide a guide for determining the optimal design condition among various design conditions.
도 1은 본 기술의 냉각탑 견적가 산출 절차를 나타내는 순서도.1 is a flow chart showing a cooling tower estimation calculation procedure of the present technology.
상술한 바와 같은 목적을 달성하기 위한 본 발명의 특징은, 냉각탑의 사양에 따라 유사한 선행 프로젝트를 선정하는 단계와; 설계 파라미터에 따라 해당하는 냉각탑 금액을 상기 선행 프로젝트에 입력하는 단계와; 견적을 산출할 프로젝트의 설계 파라미터를 입력하는 단계와; 상기 냉각탑 금액과 비교하여 상기 설계 파라미터에 대응하는 사이징 팩터를 구하고, 각 사이징 팩터를 곱하여 냉각탑의 견적가를 산출하는 단계를 포함하는 것을 특징으로 하는 화력 발전소의 냉각탑의 견적가 산출 방법을 제공하는데 있다.Features of the present invention for achieving the object as described above comprises the steps of selecting similar prior projects according to the specifications of the cooling tower; Inputting a corresponding cooling tower amount into the preceding project according to a design parameter; Inputting design parameters of a project for which an estimate is to be calculated; Comprising a step of obtaining a sizing factor corresponding to the design parameters compared to the cooling tower amount, and multiplying each sizing factor to calculate the estimated price of the cooling tower, it provides a method for calculating the estimate of the cooling tower of the thermal power plant.
이하, 본 발명의 실시예를 첨부한 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 냉각탑 업체에서 기술자료로 제시한 각 설계 조건 별 가격에 영향을 미치는 요인들을 커브(curve)로 제시하고, 이를 데이터화 하여 각 조건에 의한 사이징 팩터를 고려해 냉각탑의 견적가를 산출한다.In the present invention, the factors affecting the price of each design condition presented by the cooling tower company as a technical data are presented in a curve, and the data are calculated to calculate the estimated price of the cooling tower in consideration of the sizing factor according to each condition.
도 1은 본 발명에 따른 냉각탑 견적 산출 절차를 나타내는 순서도로서 도 1을 참조하면, 먼저 구체적인 냉각탑의 사양(예: Wet type, Mechanical type, Concrete structure)이 결정되면, 이와 유사한 선행 프로젝트를 검색하여 비교 대상 프로젝트로 선정한다(S1).1 is a flow chart illustrating a procedure for calculating a cooling tower estimate according to the present invention, referring to FIG. 1, first, when a specification (eg, wet type, mechanical type, concrete structure) of a specific cooling tower is determined, a similar preceding project is searched and compared. Select the target project (S1).
그리고, 별도의 데이터베이스를 통해 각 설계 파라미터에 따른 정해진 공급역무에 해당하는 냉각탑 금액을 상기 비교 대상 프로젝트에 입력한다(S2). 해당 설계 파리미터로는 습구 온도(Wet Bulb Temperature: WBT), 냉각탑에서 냉각시켜야 할 총 물의 용량인 플로우 레이트(Flow Rate: W), 냉각탑의 물의 입구 온도와 출구 온도와의 차이를 나타내는 온도 범위(Temperature Range: TR), WBT와 출구 온도와의 온도차를 나타내는 어프로치(Approach) 등이 있다.Then, the amount of cooling tower corresponding to the fixed supply service according to each design parameter through a separate database is input to the comparison target project (S2). The design parameters include wet bulb temperature (WBT), flow rate (W), which is the total volume of water to be cooled in the cooling tower, and a temperature range indicating the difference between the inlet and outlet temperatures of the cooling tower's water. Range: TR), and Approach indicating the temperature difference between the WBT and the outlet temperature.
그런 다음, 해당 견적을 산출할 프로젝트의 설계 파라미터를 입력하는데, 이때, 공급역무는 상기 비교 대상 프로젝트의 해당 공급역무와 동일해야 한다(S3).Then, input the design parameters of the project to calculate the estimate, wherein the supply service must be the same as the corresponding supply service of the comparison target project (S3).
그 후, 상기 설계 파라미터에 대응하는 사이징 팩터를 구하고, 각 사이징 팩터를 곱하여 냉각탑의 견적가를 산출한다(S4).Thereafter, a sizing factor corresponding to the design parameter is obtained, and the estimated value of the cooling tower is calculated by multiplying each sizing factor (S4).
상기와 같이 본 발명의 냉각탑 견적 계산 방법에 의하면 어떤 타입의 냉각탑이라도 그 비교 대상만 존재하면 견적가 산출이 가능하다. 다만, 냉각탑의 타입이 다를 경우(Natural tower 와 Mechanical Tower, Concrete structure 와 FRP structure 등) 해당 냉각탑의 견적 산출이 불가능하다.As described above, according to the cooling tower estimation calculation method of the present invention, any type of cooling tower can be calculated if only the comparison target exists. However, if the type of cooling tower is different (Natural tower and Mechanical Tower, Concrete structure and FRP structure, etc.), it is impossible to estimate the cooling tower.
또한, 본 발명에 따른 실시 예는 상술한 것으로 한정되지 않고, 본 발명과 관련하여 통상의 지식을 가진 자에게 자명한 범위 내에서 여러 가지의 대안, 수정 및 변경하여 실시할 수 있다.In addition, the embodiment according to the present invention is not limited to the above description, and various alternatives, modifications, and changes can be made within the scope apparent to those skilled in the art.
이상과 같이, 본 발명은 발전소에 공급되는 아이템 중 상당한 금액을 차지하는 냉각탑의 비용에 대한 예상을 전혀 할 수 없는 상황에서 냉각탑 견적 산출이 가능하도록 한다. 또한, 짧은 시간 내에 견적을 산출할 때 유용하게 사용되며, 실제 견적 접수 후에도 업체에 이를 통해 금액의 적정성을 검토하여 업체에 최적의 금액을 제시토록 유도할 수 있으며, 상당한 원가절감도 이룰 수가 있는 효과가 있다.As described above, the present invention makes it possible to estimate the cooling tower in a situation where it is impossible to predict the cost of the cooling tower that occupies a considerable amount of items supplied to the power plant. In addition, it is useful when calculating the quotation within a short time, and even after receiving the actual quotation, the company can induce the company to suggest the optimal amount by reviewing the adequacy of the amount through the actual quotation. There is.
