Abstract Steam separator package including swirl vane separator, gravity and dryer is crucial for guaranteeing steam humidity below 0.1% in SG. In this paper, a high-pressure flow system is designed to study the performance of a full-scale steam separator package at a rated pressure of 6 MPa and temperature of 275.6 °C. To obtain separation efficiency, moisture carryover and pressure drop of each stage, the Reynolds number steam and water are 1 × 106–6 × 106 and 8.27 × 105–3.2 × 106, corresponding to 25–145% load. Results indicate that the separation efficiency ranges from 97 to 99%, 0.5 to 2% and 0.2 to 0.75% for separator, gravity and dryer. The moisture carryover ranges from 2 to 16% and 1 to 4% for separator and gravity, and is below 0.1% at dryer outlet. The pressure drop ranges from 2 to 24 kPa and 0.3 to 3 kPa for separator and dryer. Empirical correlations for swirl vanes are proposed, which are responsible for more than 85% and 70% of total separation efficiency and pressure drop.

全尺寸SG汽水分离器分离性能的实验研究

摘要 蒸汽分离器包包括旋流叶片分离器、重力和干燥器，是保证SG中蒸汽湿度低于0.1%的关键。在本文中，设计了一个高压流系统来研究全尺寸蒸汽分离器组件在额定压力为 6 MPa 和温度为 275.6 °C 下的性能。为了获得各阶段的分离效率、水分携带量和压降，蒸汽和水的雷诺数分别为1×106-6×106和8.27×105-3.2×106，对应25-145%的负荷。结果表明，分离器、重力和干燥器的分离效率范围为 97% 至 99%、0.5% 至 2% 和 0.2% 至 0.75%。分离器和重力的水分携带范围为 2% 至 16% 和 1% 至 4%，并且在干燥器出口处低于 0.1%。分离器和干燥器的压降范围为 2 至 24 kPa，0.3 至 3 kPa。
