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0．17～0．22MPa范围内有实用意义的加热实验，当m为10．56时用120L／h水引射34kg／h蒸汽和研为4．69用170L／h水引射33kg／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0．05～0．6MPa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。
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 heater could exceed 106 ℃, which is superior to the heating performance of existing heater systems. The results of jetting experiment when the inlet pressure is at 0.05 MPa to 0.6 MPa indicate that it is safe and feasible to use the jetting-mixing low-pressure heater in low-pressure heating systems.
