摘要

PURPOSE: A gas sealing device of a soot blower of an oxy-fuel combustion boiler and an oxy-fuel combustion boiler system are provided to improve sealing efficiency by allowing a floating stuffing box to cut off external air flowing through the perforated part of a soot blower. CONSTITUTION: A gas sealing device of a soot blower of an oxy-fuel combustion boiler comprises a support(10), a floating stuffing box(20), and a sealing unit(40). The support is fixed to the wall surface(2) of a boiler. The stuffing box is relatively moved to the support. The sealing unit is installed inside the stuffing box and is adhered to the outer surface of a steam jetting pipe(1).
