Inorganics flow out of the furnace through smelt spouts, Fig. 11.6 The amount of smelt inside the recovery boiler furnace has been measured by Kelly et al. (1981). They found the smelt content per furnace unit area to be about 250 kg/m 2 for a decanting Combustion Engineering (CE) unit and about 140 kg/m 2 for a Babcock&Wilcox (B&W) unit.
Read MoreBoiler surveys Boilers and thermal oil heaters are to be surveyed twice in every five-year period. The periodicity of the boiler survey is normally 2.5 years. Steam boilers, superheaters and economisers are examined internally and externally. To this end, boilers are
