acc空冷器性能测试程序

ring with contract requirementРNoise level of ACC: when all fans running at 100%, noise level should below 45 dB(A) at the point 170m away from ACC;when all fans running at 110%, noise level should below 50 dB(A)Р试验工况 test caseР空冷系统性能考核试验要求的试验工况如下:Performance test under the conditions as below,Р本工程根据ASME PTC 30.1-2007 Air-Cooled Steam Condensers Performance Test Codes标准,管束上方1m处不利风向风速按5m/s考虑。Р在厂址区域自然的空气干球温度为13.2℃,汽轮机TMCR工况的排汽量为629.252t/h,排汽焓为2468.8kJ/kg,空冷凝汽器风机100%额定转速条件下时,应保证汽轮机排汽口处背压不超过11.7kPa(根据与波黑业主的会议纪要Tech-Clari_T-3_Master_5th_Round_2010-05-27第95条)。Р本工程在夏季自然空气设计干球温度为23.2℃时,汽轮机SUM1工况的排汽量为665.017t/h,排汽焓为2491.3kJ/kg,空冷凝汽器风机100%额定转速条件下时,应保证汽轮机排汽口处背压不大于18kPa。Р在夏季空气设计干球温度为34℃时,汽轮机SUM2工况的排汽量为你,排汽焓为2576.0kJ/kg,空冷凝汽器风机100%额定转速条件下时,应保证汽轮机排汽口处背压不大于_31.13_kPa(乙方填写,要求不大于32kPa)。Р以上三个工况作为空冷凝器系统考核工况。
