KFS has a long and successful history of in-house proprietary physical and mathematical modelling which is used for every single project as part of the burner design process. In recent years our traditional techniques have been expanded with the addition of CFD (computational fluid dynamic) modelling. KFS use a combination of commercial codes with specifically customised models for use in rotary kiln and calciner applications.

The use of CFD modelling now allows detailed examination of flame and temperature profiles, their impact on process conditions, and emissions. KFS experience combined with extensive validation with plant data and previous projects ensures a high degree of confidence in the CFD results.

This in turn provides KFS customers with assurance of a successful project.

MODELLING

KFS provides their customers with the world’s most experienced modelling team having worked on over 200 applications.

KFS physical modelling techniques include:

aerodynamic – provides visual interpretation of flow patterns in kiln hoods, coolers, calciner vessels and ducting

combustion – used to demonstrate the efficiency of fuel and air mixing together with its impact on the combustion performance in a wide variety of processes

Combustion and heat transfer are very complex subjects that cannot be easily analysed by conventional mathematics. Prediction of the performance of burners, combustion equipment and associated plant is therefore extremely difficult and is normally carried out by trial-and-error (straight-forward calculations combined with the extrapolation of experience) or modelling (physical and mathematical analysis of the system), the former being the industrial norm.
