循环流化床锅炉冷态空气动力场试验包括主要风量测量装置标定试验、一次和二次风机系统的风量测量装置的标定、空床阻力试验、料层阻力及临界流化风量试验、流化质量试验等。该锅炉在点火启动及调试时,应进行床温控制、床压控制、冷渣器系统运行的工作。该锅炉调试中,常见故障有床温过高或过低、床压过高或过低、床面结焦、冷渣器堵塞。应合理调整床温、床压等参数,确保该锅炉安全、稳定运行。
Cold aerodynamic field tests of circulating fluidized bed boilers include calibration tests of main air volume measuring devices, calibration of air volume measuring devices of primary and secondary fan systems, empty bed resistance test, material layer resistance and critical fluidized air volume test, fluidized mass Test and so on. The boiler ignition start-up and commissioning, bed temperature control, bed pressure control, slag cooler system operation. Debugging the boiler, the common faults have bed temperature is too high or too low, bed pressure is too high or too low, bed coke, clogging slag cooler. Should be properly adjusted bed temperature, bed pressure and other parameters to ensure that the boiler safe and stable operation.
