ABSTRACT
Soot blowing is designed to remove slagging and fouling and is frequently used by an operator on each shift in a power plant. Slagging- and fouling-related combustion problems still exist and have a severe influence on a power plant in which coal has a higher tendency of slagging and fouling, so how to apply soot blowers intelligently rather than frequently to clean the heat-transfer surface and maintain a high heat-transfer efficiency inside the furnace is indispensable. In addition, intelligent soot blowing can not only reduce steam loss from unexpected blowing and avoid tube damage caused by overblowing [119], but also monitor the slagging by quantifying the slagging and its distibution. This is significant to a coal-fired power plant’s safe and economical operation.
