摘　　要：本文设计并搭建了一套用于探究航空煤油RP-3裂解结焦的实验系统。详细地介绍了航空煤油裂解实验系统各个子系统的主要构成和主要功能。然后,利用所搭建的航空煤油裂解实验系统测量了航空煤油在入口温度285℃、压力3 MPa、质量流量0.44 g/s条件下的裂解特性,实验结果表明:在上述条件下,航空煤油的临界结焦功率为730 W;其裂解过程中进出口前后压差随着加热功率逐渐增大;同时产气速率随着功率增加逐渐增大,且在结焦时由于管路堵塞会有下降的现象;同时增加加热功率有助于航空煤油的裂解。An experimental system for exploring the cracking and coking of RP-3 aviation kerosene was designed and constructed. The main components and main functions of each subsystem of aviation kerosene cracking experimental system are introduced in detail. Then, the aviation kerosene cracking experimental system was used to measure the cracking characteristics of aviation kerosene at the inlet temperature of 285˚C, pressure of 3 MPa, and mass flow rate of 0.44 g/s. The experimental results show that under the above conditions, the critical coking power of aviation kerosene is 730 W, the pressure difference between the inlet and outlet during the cracking process gradually increases with the heating power, the gas production rate gradually increases with the increase of power, and there will be a decrease phenomenon due to pipeline blockage during coking;and the increase of heating power is conducive to the cracking of aviation kerosene.
