abstract

Some results of the NPP “EST” activities on improvement of the environmental record of the stationary gas turbines, viz.GTG-1500, FRAME 5, GTN-16, which are in use nowadays in Russia, are presented. Toxic emissions reduction is achieved through combustors update. The technique of directed dosed air blow-in into the maximum fire temperature zones allows to reduce the NOx emissions to 70–130 mg/Nm3 (converted to NO2 at 15% O2 concentration) via minimal combustor design modifications. Lower NOx emissions, amounting to 15–25 mg/Nm3, can be produced through combustion of lean premixed air and fuel in the 4-burner low-toxic module. When retrofitting the GTN-16 unit combustor, the standard dome was replaced with 20 such modules.
