Modelling the thermodynamic performance of a concentrated solar power plant with a novel modular air-cooled condenser

Pressure drop analysis of steam condensation in air-cooled circular tube bundles

“…In order to alleviate deficiencies associated with current ACCs, a modular aircooled condenser (MACC) is proposed. It has been shown through previous studies by O'Donovan and Grimes [10], Moore et al [11] and Butler and Grimes [12] that this design has the potential to maximise plant output and minimise parasitic losses. However, a factor which could inhibit the performance of the MACC, or any ACC for that matter, is the pressure losses associated with the two-phase condensing flow of steam through the tube bundle.…”

Line-focusing concentrating solar collector-based power plants: a review

“…Liqreina and Qoaider (2014) compared the values of the annual mean overall efficiency, water consumption, and levelized cost of energy for the dry-and wet-cooled steam Rankine cycle-based CSP plants. Moore et al (2014) performed the technoeconomic comparison between different designs of Table 4 Properties of commonly used high-temperature oils and molten salts (Gil et al 2010;Tian and air-cooled condensers for CSP plants. A novel air-cooled condenser has also been proposed, which can be installed in a modular scale to reduce installation costs (Moore et al 2014).…”

A Numerical Study on the Performance Characteristics of a Power Plant Air-Cooled Condenser (ACC) Affected by Changes in Operating Conditions

“…Yang et al [6] 은 지정된 single-low fin tube 형상에 대해 공기측 열전달 및 압력강하 특 성을 측정하고 그 결과를 그들의 수치해석 결과와 비교하여 모델 을 검증한 후, 추가적인 시뮬레이션을 실시하여 유속, 핀 간격, 핀 높이가 공기 측의 열전달 및 압력강하 성능에 미치는 영향을 분석하였다. Moore et al [7] 은 기존과 다른 형상을 갖는 모듈형 [8] . 따 라서 실제 ACC 시스템에서는 관 내측에 흐르는 증기의 질량유량 이 균일하지 않고 기존의 연구 [3,4] 에서 언급된 것과 같이 열교환기 계수의 계산에는 난류조건인 경우 Dittus-Boelter 상관식 [10] , 층류 조건인 경우 일정 벽온도 조건을 활용하여 계산하였다.…”

“…공기 측 열전달 계수는 Teertstra [12] 가 제시한 방법을 적용하여 계산하였으며 Moore et al [7] 은 Teertstra [12] 의 계산방법이 ACC 공기측 열전달 계수의 계산에 유용하다고 보고하였다. 공기측 열전…”
