Abstract

An apparatus (12) for selecting substantially uniform sized salt-cake particles (56) from an inorganic salt recovery stream of a chemical recovery boiler (10) and injecting them into the flue gas stream (42) of the boiler. This acts to 'seed' the sodium fume and the particulate matter that rises with the flue gas stream for creation of a larger, boiler fouling particle. This larger fouling particle bonds to boiler heat transfer surfaces (51, 116, 118) with a lesser degree of adhesion than its 'unseeded' counterparts. The combination of the increased size and lower adhesion property allows for easier and quicker removal thus increasing boiler efficiency. Conventional soot blowing operations (50) are more able to remove the deposits on the boiler tubes, increasing run time and reducing the plug rate.
