In a joint venture with Babcock & Wilcox, ESI converted an existing recovery boiler to a bubbling fluidized bed boiler. This system included: one bubbling fluidized bed boiler designed to produce 450,000 pph, 850 psig/825°F superheated steam firing sludge, wood waste, and tire chips (TDF); along with an SNCR NOx reduction system; fuel handling systems for the sludge, wood waste, and TDF; sand feed and reclaim system; ash handling system; and a new distributed control system.
