The results of experimental elaboration of engineering approaches relating to environmental update of combustors for the GTK-10 10 MW, GTG-1500 1.5 MW and GT-100 100 MW gas turbine engines are presented. The combustor update was carried out by a technique of directed dosed air blow into the maximum temperature zone with in the fire space.
The advantages of the technique are as follows:
• feasibility of reduction of Nox concentration in waste gases to 50 ppm;
• simplicity and adaptability to manufacture of the structure;
• no need in changing the design of the engine components and systems;
• short-time outage of the unit at update.
