An ANSYS simulation of the multiphase complex fluid flow motion in a centrifugal device (tricanter) is presented in the paper. This centrifugal device is designed for one step efficient solution for contaminated river water processing with oil and oil products. The proposed tricanter is one of the main objectives of the project named “Common strategy to prevent the Danube’s pollution technological risks with oil and oil products CLEANDANUBE” financed by European Commission within the frame of Romania-Bulgaria Trans-Border Cooperation Program 2007 - 2013 (grant MIS-ETC code 653). Results for liquid phases (water and oil products) and for solid particles motion are presented graphically and are commented.

The more and more restrictive environment requirements in the field of pollutant emissions of co-generative plants are imposing researches related to the more efficient work of those related to the post combustion facility. The paper presents the results of a post combustion burner achieved on a test bench, when it idling operates on natural gas mixed with air or with burned gases of a gas turbine. The modeling of the measured emissions, led to NOx concentrations in ambient air that are below the limits imposed by the in force regulations related to air quality and are correlated to the real time measured data.
