Combustion technology

Increasing efficiency in combustion technology is possible in a particularly cost-effective way using CFD simulation!

Development, test and optimization

Do you want to find out how to improve boiler efficiency? Or would you like to replace the furnace or the refractory lining? Or maybe you want to use new fuels such as wood?

Flow simulations can be used to compute widely differing scenarios of combustion, fuel combinations and geometries.

We can help you to check the feasibility of such ideas and to minimize your project risk! Depending on the brief given we will support and consult you, making use of selected models and our network of contacts and, not to forget, our wide range of practical experience.

The most different fire systems can be examined:

N

Gas firing installations

N

Melting chambers (gas, metal) and their firing systems

N

Duct burners

N

Lean gas burners

N

Oil firing installations

N

Coal firing installations

N

Grate firing (RDF, waste, coal, wood)

N

Incinerating particular substances

N

GT-waste heat boilers

N

Kilns (ceramics)

Duct burners

Checking the positioning of the burners in the duct, thermal load of the internals, homogeneous incident flow, stable ignition behaviour including perfect control behaviour at low emissions; we help you to achieve these goals.

Gas burner

Whether low calorific residual gas, or upgrading with hydrogen: we can test your burners for suitability!

Industrial boilers Gas combustion

Understand the complex combustion process with your fuel, burner and boiler, only then can you save emissions and fuel and extend service life with targeted changes.

EBS grate incineration plant

By means of the pyrolysis gas model used, different fuels can be simulated as feed to the grate. Common questions are the residence time, secondary air mixing, oxygen distribution or, for example, particle deposition.

The computations can be used to investigate the following situations:

N

Flame development, e.g., the twist direction of burners

N

Burner inlet flow and pressure loss of airing system

N

Layout of over-fire airing and wall vents

N

Forecast for wall atmospheres and CO and O2 distribution

N

FG temperature at end of fire chamber

N

Temperature development in fire chamber

N

Flue gas residence times

N

Heat flow density at membrane wall

N

Heat flow density at refractory lining

N

Selection of burner types

N

Qualitative emission forecasts for NOx, CO, CO2, O2

FAQ

Common questions

Can the emissions NOx, CO be predicted accurately with the CFD calculations?

The prediction models have become more and more precise over the last few years, so that a prediction of NOx, CO, O2 can be calculated with sufficient accuracy.

We recommend a prior validation with your systems and fuels, if quality characteristics are to be checked before installation so that contractual security can be guaranteed.

Are the chosen burners suitable for the existing combustion chamber?

In addition to our CFD calculations in which we verify burner position, flame propagation, ignition behaviour and emission behaviour, we also offer water and steam calculations.

Can another fuel such as hydrogen be used in the existing system?

We can offer you a comprehensive study on your question, as well as a CFD study to support your planning.

In addition to the combustion calculation, we can check with your subcontractors whether your valves and safety equipment are adequate.

How can emissions and efficiency be further improved?

In addition to the usual primary and secondary NOx abatement measures, we can test your steam system for the suitability of thermochemical energy enrichers.
