【摘要】 在高温气冷堆吸收球停堆系统中,吸收球的气力输送过程是影响系统正常运行的关键因素。其中吸收球的球径大小又对吸收球的气力输送过程产生显著影响。基于吸收球外形规则,球形度好等特点,在气固两相流理论的基础上就吸收球球径大小对各参数,包括各种速度,风机的理论功率等参数的影响规律进行了定量的分析研究。研究结果有助于对吸收球气力输送系统的设计。更多还原

【Abstract】 Pneumatic conveying of small absorber ball has significant influence on HTR normal run.Absorber ball size also affects pneumatic conveying of absorber ball distinctly.Regular shape and fine sophericity are characteristics of absorber ball. Based on theory of gas-solid two phase flow,effects of absorber ball size on different parameters(including various velocity, theoretical power of blower etc) were quantitatively studied.Research results help to design pneumatic conveying system of absorber ball.更多还原
