| 摘 要： | 热力发电厂低压加热系统凝结水加热模拟实验,对结构相同,面积比m为10.56、4.69、2.64和1.69的引射混合式低压加热器进行了引射性能与加热性能实验,着重进行了入口水压在0.17～0.22 MPa范围内有实用意义的加热实验,当m为10.56时用120 L/h水引射34 kg/h蒸汽和m为4.69用170 L/h水引射33 kg/h蒸汽,使加热器出口水温高于106 ℃,优于目前低压加热系统的加热性能;入口水压在0.05～0.6 MPa期间的引射实验结果表明,在低压加热系统中采用引射混合式低压加热器是安全、可行的.

| Abstract: | Heating simulation experiments on the low-pressure heating system of a power plant are carried out,including experiments on the jetting and heating performance of a jetting-mixing low-pressure heater with the structure-area ratios of m=10.56,4.69,2.64,and 1.69,and a practical heating experiment with inlet hydraulic pressure at 0.17 MPa to 0.22 MPa.When 120 L/h water ejected the steam with 34 kg/h as m=10.56,and when 170 L/h ejected the steam with 33 kg/h as m=4.69,the outlet hydraulic temperature of the hea... |
