RESULTS OF MODERNIZATION

Natural gas savings 10-15%

Reduction of pollution: NОx not more than 10÷50 мg/м3 (25

ppm); CO not more than 5÷10 мg/м3 (8

ppm) Increasing project value of turbine

up to 30% Wide range of turbine power regulation with high gas savings

and low NOx and CO from 10 to 120%

Fast recoupment of investment 10-24 months

High level of uniformity of temperature field in gas combustion zone and vibration decrease prolong service life of turbine (primarily a catalyst).

Opportunity to fulfill short term tasks (from 1 to 30 days) reduces losses from downtime.

No necessity in purchasing new turbines and accessory equipment.
