According to the coking monitoring and early warning device system and method for the coal-fired power plant boiler, the smoke temperature monitoring devices and the wall temperature monitoring devices are additionally arranged on the partition screen, the final-stage superheater and the final-stage reheater of the coal-fired power plant boiler, and calculation is carried out based on mass smoke temperature data and wall temperature data; and on the basis of the contamination coefficient, indirect monitoring and digital visual display of information such as the coking condition, the ash deposition degree and the coking position of the boiler are carried out. The coking monitoring and early warning method is more accurate and advanced compared with the original manual judgment of the coking condition of the boiler, can guide an operator to carry out related optimization operation, and ensures the safe and stable operation of the coal-fired power plant boiler. 本发明提供一种用于燃煤电站锅炉的结焦监测及预警装置系统及方法，通过在燃煤电站锅炉的分隔屏、末级过热器和
