  • Patent number: 7938910
    Abstract: A method for cleaning a gas turbine unit. The invention further relates to a nozzle for use in washing the gas turbine unit. The nozzle is arranged to atomize a wash liquid in the air stream in an air intake of the gas turbine unit and comprises a nozzle body comprising an intake end for intake of said wash liquid and outlet end for exit of said wash liquid. The nozzle further comprises a number of orifices that are connected to the outlet end and respective orifice is arranged at a suitable distance from a center axis of said nozzle body, whereby the local density of the injected wash liquid in a desired area can be increased with preserved droplet size and thereby the efficiency of the cleaning process can be significantly improved at the same time as the risk for damaging the components in the gas turbine unit is significantly reduced.

  • Patent number: 7762476
    Abstract: The present technique provides a system and method for improving atomization in a spray coating device by internally mixing and breaking up a desired coating fluid prior to atomization at a spray formation section of the spray coating device. An exemplary spray coating device of the present technique has an internal fluid breakup section comprising at least one fluid impingement orifice angled toward a fluid impingement region. In operation, the internal fluid breakup section forms one or more fluid jets, which impinge one or more surfaces or one another in the fluid impingement region. Accordingly, the impinging fluid jets substantially breakup particulate/ligaments in the coating fluid prior to atomization. The resulting spray coating has refined characteristics, such as reduced mottling.

  • Publication number: 20090314500
    Abstract: Apparati for generating a mist are disclosed. One apparatus is disclosed, which has an elongate hollow body (12) and an elongate member (14) located within the body (12). A transport fluid passage (16) and a nozzle (32) are defined between the body (12) and the elongate member (14). The transport fluid passage (16) has a throat portion of reduced cross-sectional area and is in fluid communication with the nozzle (32). The elongate member (14) includes a working fluid passage (26) and one or more communicating openings, such as for example, bores, annuli, and combinations thereof, (30) extending radially outward from the working fluid passage (26). The openings (30) permit a working fluid (e.g. water) to be passed into the transport fluid passage (16), whereupon the working fluid is subjected to shear forces by a high velocity transport fluid (e.g. steam). The shearing of the working fluid results in the generation of a mist formed from droplets of substantially uniform size.

  • Patent number: 7472845
    Abstract: An orifice disc for a fuel injector includes two orifices that provide a desired interaction between two fuel flows to increase fuel atomization and improve combustion performance. The orifice disc includes a first orifice and a second orifice that are disposed at an interaction angle relative to each other. The orifices are orientated relative to each other such that fuel flow exiting the outlets impinges on each other to further reduce the size of fuel droplets. Large dramatic changes in momentum caused by the impingement of fuel flows disintegrates fuel droplets into much smaller finer fuel droplets that provided enhanced atomization.
