Sootblowing control Figure 1 shows the main monitoring and control functions of the Kraft mill’s recovery boiler. The following article concerns with sootblowing monitoring and control. Reasons for sootblowing Sootblowing is a necessary function in addition to effective control. The emissions (particulates, sodium and calcium compounds) cause the fouling of the boiler, and therefore the
