Abstract

The invention provides a boiler water wall ash pollution monitoring system. N soot blowers are arranged on a boiler water wall, N is larger than or equal to 1, the N soot blowers are located at M different heights, M is larger than or equal to 1, n soot blowers are arranged at each height, and n is larger than or equal to 1 and smaller than or equal to N. The monitoring system is characterized bycomprising J fin thermocouples, K pipe wall thermocouples, a temperature data collector and a data processing platform. The fin thermocouples are arranged near the soot blowers, on one hand, the number of the required fin thermocouples is small, and on the other hand, once it is monitored that the pollution rate of the water wall area where the thermocouples are located is high, the soot blowers near the thermocouples can conduct soot blowing operation under control, the heating surface is kept clean, and the soot blowing effect is monitored.

Description

technical field [0001] The invention relates to the technical field of intelligent control systems for combustion equipment, in particular to a dust monitoring system for boiler water walls. Background technique [0002] The boiler is the key equipment for the operation of the power station. During the operation of the coal-fired boiler, a large amount of ash, a by-product of coal combustion in the furnace, will be produced, which inevitably causes varying degrees of ash on the heating surface. Soot blowing is an effective means to remove dust and keep the boiler heating surface clean. The soot blower uses a certain soot blowing medium (water, steam, sound wave, etc.) to blow the heating surface, remove the dirt on the surface, and restore the surface to a clean state. The soot blowing system is an important means to improve the unit availability and ensure the safe and economical operation of the unit. [0003] At present, the soot blowing operation of large-scale power p...
