While there are different thoughts on this, current practice with modern equipment (supersonic nozzles, etc.) is to use superheated steam for sootblowing. One reason is to minimize condensate droplets that have been proven to contribute to tube erosion. There are still boiler manufacturers that provide fittings on the drum (saturated) and label them as sootblower steam connections. Look up six references and, depending on publication dates, 4 will prefer superheated, 2 will go with saturated.
