CSFMB© (previously called CSFB) with the commercial designation CeSFaMB™, is a comprehensive simulator for Bubbling and Circulating Fluidized Bed and Moving Downdraft and Updraft Bed equipment. In addition, the newest version is able to simulate Entrained Flow Combustors and Gasifiers as well. This powerful simulator is able to accurately reproduce and predict the operational conditions of pilots as well as large-scale industrial units. The mathematical model has been classified as Advanced by a recent paper at Progress in Energy and Combustion Science because it includes all sub-models related to combustion and gasification process and has been validated against many operations carried in pilot and industrial-size equipment.

"Thank you for the CeSFaMB. It is really a powerful tool. We successfully applied the software for simulations carried out in both oxygen-enriched conditions and for CLC units. We performed 1.5 D models for both 0.1MWth OxyFuel-CFB Test Rig as well as for complex geometry and laboratory scale fluidized bed CLC equipment. We strongly recommend this tool".

"The software CSFMB (CeSFaMB) has been applied for operation verification and designing gasifiers for more than a year by the R&D team of VSE (Vale Solutions in Energy) with remarkable performance. Constant internal validation of this simulator has been made with incredible correlation between real and simulated data, which give reliability to the entire design/operation process in real gasification plants. This is why CSFMB is the main tool at VSE for future gasifiers’ designs for both coal and biomass."

“I can confirm that CSFMB is being utilized at NETL, as is the supporting documentation, including both versions of your book. We are very impressed with the work you have done to develop this valuable tool and, as discussed when visiting, are evaluating it as a potential application within the C3M environment.”

“Several benefits can be found during the application of CeSFaMB software for coal gasification process in Institute of Engineering Thermophysics, Chinese Academy of Science. They are summarized as follows: (1) The detailed information, including process temperature, components as well as pressure distribution can be given in the reactor chamber and they are the important parameters for coal gasification process analysis and design. (2) The feedback for the user enquiries as well as software maintenance are excellent and helpful. (3) We are getting lots of benefits from the updating of the software in operation function and algorithm. (4) We are sure that more research work and results can be achieved with the further application of the software.”

"I found the use of the program (CSFMB) very easy to learn. The results of the simulations are presented in a very accessible way and are very extensive. Using the program, the designer gets more insight and feeling of the actual process occurring in the gasifier and its relationship with several design parameters. The program can therefore be used as a useful design tool"

The following new publication demonstrates the quality of CeSFaMB 4th Generation predictions against experimental results:
Zylka A., Kryzywanski J., Czakiert T., Idziak K., Sosnowski M., Grabowska K., Prauzner T., Nowak W., Numerical simulations of CuO-based oxygen carrier CLC by the use of CeSFaMB the 4th Generation, 5th International Conference on Contemporary Problems of Thermal Engineering, CPOTE 2018, 18-21 September 2018, Gliwice, Poland, Institute of Thermal Technology.
The new 4th CeSFaMB™ Generation is more robust than the previous series. In addition to all improvements made on previous versions, this new generation includes many other possibilities such as:
- More options for convergence and control of the whole simulation.
- Increasing possibilities for users to set special kinetics that fit any particular situation or fuel.
- Additional chemical species, which characterize calcium and magnesium solids, were fed to the equipment.
- Possibility of describing the composition of extra solids (including inert solids) inserted or present in the equipment.
- Allow simulations of Chemical Looping Combustors and Gasifiers (CLC).
- Permit simulations of Calcium Carbonate Looping Equipment (CaL). It covers processes where magnesium and mixtures of Ca and Mg are fed into the reactor.
