Experimental Refinement of Technologies for Environmental Update of Gas Turbine Units Applied to Electrogenerator Driving

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.
