Throughout the production life of the TB turbine, the design and performance of the engine has been improved, whilst maintaining its philosophy of reliability and ease of maintenance on site.
Since the first TB3000, rated at 3100 bhp*, the TB has undergone three power enhancement changes;
3990 bhp* - TB4000
4900 bhp* - TB5000
5200/5400 bhp* - TB5000 uprate
For the latter increase of power 4900 bhp* to 5200/5400 bhp*, we can offer to uprate your TB5000 gas turbine. This uprate to 5200/5400 bhp* can also be offered for some later TB4000 models.
(*Power output figures given based on ISO conditions.)
The TB type gas turbine, renowned for its ruggedness and reliability, numbering in excess of 840 units operating throughout the world, was originally brought into service in 1970.

The TB5000 Gas Turbine Uprate to 5200/5400 bhpFor TB5000 Gas Turbines (and some later TB4000 models)
The Uprate
To increase the nominal ISO power output of a TB5000 from 4900 bhp to 5200/5400 bhp, the design maximum temperature was raised from 877°C to 900°C, giving an increased exhaust temperature of 495°C.
To cater for this increase in temperature, various design changes were made to the turbine gas generator.
The combustion system is modified using sealed chambers, the swirler tubes and their extensions having special mating features to improve temperature spread to the compressor turbine.

The Parts
For retrofitting to a 4900 bhp rated TB5000, new swirler cones, flame tubes and extensions are required for the combustion system.
The cooling air for the first stage CT blades is routed through holes in the quadrants, hence the uprate requires the retrofit of new bladed quadrants.
The abradable seals of the second stage are fitted via a ‘T’ slot in the stator ring, hence the retrofit of a new stator ring will be required.
Compressor Cleaning
Early TB5000 gas turbines were fitted with a dry solids compressor cleaning system.
Due to the nature of the cooled blades required for the uprate, the cooling holes would become blocked with solids, defeating the cooling system. It is therefore essential that a fluid wash system is retrofitted.
When requesting a quote for a TB5000 uprate, please advise if a fluid wash system is already fitted.
Limitations
Whilst the TB5000 can be uprated to provide up to 5400 bhp output, the following points should be noted:
Limitations of the driven unit
Limitations of the gearbox and coupling
