Fouling monitoring and intelligent sootblowing control technologies for coal-fired boilers
摘要
Abstract
On the basis of analyzing the harm of ash slagging in heating surface of power plant boilers and the shortages of time-based quantitative sequential soot blowing methods, the monitoring methods for ash deposition and slagging in heating surface of utility boilers were reviewed, such as the monitoring methods based on the flue gas temperature at the furnace outlet, the heat flowmeter method, the temperature difference at back side of the water wall method, the monitoring method for furnace local pollution based on acoustic temperature measurement, the fouling monitoring technology for convection/semi-convective semi-radiative heating surface using clean factor, and the fouling monitoring technology for rotary air preheaters. Moreover, the deficiencies of researches on sootblowing optimization strategy and the current research hotspots were discussed, the application status of intelligent algorithm in boiler sootblowing optimization and the products and technical route of sootblowing optimization of large foreign companies were also summarized.关键词
