[ Combustion dynamics affects plant performance

Combustion dynamics or humming can cause serious

material and financial damage. For instance, heat release

oscillations destabilize combustion and consequently

destroy crucial parts of a gas turbine’s hardware, resulting

in a long outage.

[ Maximizing combustion stability

Over the years, Laborelec has gathered valuable insight

into all parameters affecting the combustion process. This

enables our experts to give advice on every one of the

various aspects influencing combustion stability and hence

improve a power plant’s efficiency and availability.

• greaterefficiency

Thanks to Laborelec’s many years of experience, we have

assembled a huge historical database on combustion

behaviour. This rich set of information enables us to

advise various types and sizes of gas turbines on tuning

the combustion process to achieve maximum efficiency.

• increasedavailability

Laborelec is able to prevent combustion-related

damage. We have the experts and the equipment to

closely monitor crucial combustion parameters and

provide advice on the most appropriate preventive

actions. In the event of a problem, we can also assist

in troubleshooting.

Laborelec offers various expert services

for improving combustion stability. We

are able to assist gas turbines in every

one of the following phases:

[ Assessing combustion systems

Laborelec has identified best practices during its

vast experience with combustion processes within

the GDF SUEZ Group. This enables us to assess

any combustion system and advise operators on

potential improvements.

[ Closely monitoring combustion performance

Laborelec experts have mastered various tools

to measure and monitor combustion. They also

develop their own combustion monitoring tools.

One such tool was built for 9FA gas turbines. Given

this extensive background, our experts can quickly

identify problems and advise on the necessary

preventive actions.

[ Troubleshooting combustion-related problems

Laborelec offers troubleshooting in case of a

problem within the gas turbine’s combustion

chamber. We have professionals in every domain

of expertise, from materials to combustion.

[ Professional assistance during tuning

Improving combustion stability requires precise

fuel staging control in the combustion chamber.

Laborelec has the specific combustion expertise

to assist in fine-tuning the parameters for

optimal combustion.
