摘　　要：以流化床快速热裂解装置加热系统为研究对象,通过数值计算和试验分析的方法,对该系统进行设计和检测。结果表明,该系统内温度波动满足所需温度场的要求,并可实现对温度场的实时监测和控制。由于2#温控仪所连接的热电偶处于反应段中间位置,达到稳定状态的缓冲时间较长,为了让每个温控仪能同时趋于稳定状态,在为反应器加热时,应先让2#温控仪工作10 min,再开启其余温控仪;该加热系统不仅升温速率快,而且能在短时间内同时达到设定温度,并保持在上下10°范围内稳定波动。A heating system of fluidized bed pyrolysis device was studied through the method of numerical calculation and experimental analysis. The results of simulation test show that, the system can monitor and measure the temperature in real time on the reactor at different heights, and realize the independent control of temperature. Since the thermocouple connected with the 2# temperature controller is located right in the middle of the reactor, it will need a longer buffer time to reach the stable state. When the reactor is heated, in order to make each temperature controller be able to converge to a steady state at the same time, the 2# temperature controller should first work after ten minutes, and then turn on the rest of the temperature controllers. The heating system not only has a fast heating rate, but also can reach the set temperature in a short time at the same time, and maintain it stably fluctuating in the range of 10° around the set temperature.
