  • Arrangement for treating exhaust gases of an internal combustion piston engine in a marine vessel and method of operating an arrangement for treating exhaust gases
    Patent number: 10174662
    Abstract: An arrangement for treating exhaust gases of an internal combustion piston engine in a marine vessel, includes an exhaust gas channel coupled at its first end to the engine and having its second end opening to the environment, and a scrubber unit arranged between the first end and the second end of the exhaust gas channel. The arrangement has an exhaust gas channel cleaning system arranged to apply cleaning liquid on inner surface of the exhaust gas channel to a portion of the exhaust gas channel between the scrubber unit and the second end of the exhaust gas channel.

  • Method of measuring density properties of a particle distribution
    Patent number: 7131343
    Abstract: A method and a device for measuring density properies of a particle distribution, in which method a first parameter relating to the particle distribution is measured at a first measuring point (302), at least part of the flow that passed through the first measuring point is guided to the second measuring point (304), a second parameter relating to the particle distribution is measured at a second measuring point (305), and said first and second parameters relating to the particle distribution are used to determine at least one density property of the particle distribution of the original flow (306).

  • Method for measuring properties of a particle distribution
    Patent number: 7066037
    Abstract: A method and a device for measuring properties of a particle distribution, in which a parameter relating to the mobility of the particles is measured at one measuring point (302) and a parameter relating to the aerodynamic size of the particles is measured at a second measuring point (305). By means of the measured parameters, at least one property of the particle distribution of the original flow is determined (306).
