The purpose of the unit is to supply electric energy to industrial and domestic facilities, to compensate for lack of energy during peak loads, and to operate on a standby basis. The unit is a mobile automated installation. The unit is equipped with system for starting and accepting loads with subsequent continuous operation, the systems of protection and indication of the state of the main engine parameters, as well as the modular noise suppression system. Operator’s compartment is separated from equipment room by double wall.

Main advantages:•high reliability;•works steadily as independent unit and in parallel with external power system;•features high maintainability and is simple and easy to control;•does not require big investments for putting into operation;•transportability.

GAS TURBINE ENGINE D-336

Quantity of GTE type D-336 in usage - 154 piecesThe total operating time of GTE D-336 - more than 2 500 000 hours

Gas Turbine Engines D-336 are used as a gas compressor drive, gas lifting and crude oil pumping aggregates of capacity 6,3 МW, and also as a power plants generator drives. Engines successfully operate in different climatic zones at an ambient temperature from -60 ° C to +50 ° C at altitudes above sea level up to 2000 m.

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.
