Abstract
The invention relates to a system (1) connectable to a boiler, the system comprising housing (2) connectable to the boiler defining a shock wave chamber (3). An electrically conducting wire (4) is provided in the shock wave chamber, and electrical means (5) are provided for generating an electrical discharge pulse through the wire such that to evaporate the wire. Thereby a shock wave for is generated for cleaning of dust deposit from surfaces in the boiler. Further to this, a method for cleaning a boiler is disclosed.
Claims14
A system (1) connectable to a boiler, the system comprising a housing (2) connectable to the boiler defining a shock wave chamber (3), an electrically conducting wire (4) provided in the shock wave chamber, and electrical means (5) for generating an electrical discharge pulse through the wire such that to evaporate the wire and generate a shock wave for cleaning of dust deposit from surfaces in the boiler.
The system according to any one of the preceding claims comprising a wire feeding arrangement (8) configured to feed electrically conducting wire into the shock wave chamber to replace the wire after a discharge.
The system according to any one of the preceding claims wherein the wire is a metal wire having dimensions in the range of 0.1-0.9 mm, preferably in the range of 0.15-0.5 mm.
The system according to any one of the preceding claims in the form of a movable unit for convenient transportation to and from a boiler, preferably comprising a set of wheels.
The system according to any one of the preceding claims further comprising a purge-air system configured to provide a controllable atmosphere in the housing, preferably comprising a pumping means for pumping air into the housing.
