FCT COMBUSTION NEWSLETTER: SEPTEMBER 2020
It is hard to comprehend what many people across the world have had to endure this year and what is still to follow. The Covid-19 pandemic has caught all of us by surprise yet has probably had as much impact on most of our lives globally as any other event in history. It shows how vulnerable we all are to factors entirely out of our control. Our hearts go out to those who have been severely impacted by this disease either through the health of those close to you or by the economic fallout that is still emerging.
We trust that human endeavour and enterprise will find the way to combat all of this and life will revert to some normality in the near future.
We are thankful that the impact on FCT has not been major so far. We have been able to successfully continue delivery of our projects albeit with some compromises and work around, and we are grateful for the new orders that have continued to come despite the difficulties our customers face. It certainly has helped that we have many regular and trusted customers that we continue to work with during this pandemic.
As many of you know, we have full operating companies in most of our key markets, and it is a major advantage that we can service our projects and customer needs from these local bases as travel restrictions apply to most regions of the world now.
FCT is increasing its efforts toward new product development during this time using internal and external resources to progress various environmentally friendly technologies for combustion in mineral processing and cement manufacture. We have also expanded the scope of what we offer to complete operating plant in some instances.
The future is not clear for any of us right now, but regardless of that, FCT is here to work to fill our customer needs in the best way we can. To that extent, our operations are continuing normally, we have retained and increased staff levels and are geared to increase our presence in our markets.
I wish everyone a safe and healthy year and trust that our next newsletter will come to you in better times.

PEOPLE OF FCT
At FCT, we know that our continued success is largely due to our team’s commitment to providing the best products, service and expertise across all our offices. We are pleased to introduce the newest additions to our team:
Karsten Bartnicki, Head of Projects, FCT Combustion (Asia Pacific)
We are pleased to welcome Karsten Bartnicki as Head of Projects for FCT Combustion’s Asia Pacific office. With extensive experience managing both projects and teams across Europe, China, Canada and Australia, Karsten’s most recent role was as CEO of Rema Tip Top Industry Australia.
Karsten has also held previous senior management and director positions with FLSmidth Mining Australia, Roy Hill (Hancock Prospecting), SNC Lavalin Asia Pacific and Sandvik Mining System China. Having joined FCT Combustion in April, Karsten’s wealth of knowledge has already proven a valuable asset to the leadership team and instrumental in the delivery of projects across the region.
Roger Hassold, Operations Manager, FCT Combustion (Asia Pacific)
Perhaps a familiar face to many of our customers, Roger Hassold has recently moved from leading the sales team in our Asia Pacific office to now managing Operations. Roger has extensive experience in Process Engineering, Production Management and Technical Management, having worked at Adelaide Brighton Cement for many years before joining FCT in 2014 as a Process Engineer and later Sales Manager (Asia Pacific).
Roger’s experience from the ‘client’ side has proven instrumental, as he has experienced first-hand how pyro-processing improvements can have a profound effect on the production and quality of processing plants. With this in mind, Roger now leads the Engineering Team to technical excellence.

FCT commits to low carbon research initiative led by the University of Adelaide
We are pleased to announce our commitment to support a research initiative led by the University of Adelaide, which aims to enable heavy industry to transition to a low carbon environment. The Heavy industry Low-carbon Transition Cooperative Research Centre (HILT CRC) will focus on hydrogen utilization, CO2 capture and storage, use of biomass and waste derived feedstock, and solar thermal energy.
The University of Adelaide is in the top 1% of universities in the world and ranks 7th in the world for mining and mineral engineering. FCT Combustion and the University of Adelaide have collaborated on the development and commercialization of low NOx burner technology for more than 30 years, and we are proud to continue to support research into new and exciting technologies that will ultimately enable our customers to move to a low carbon operating regime.
Whether it is outcomes from this program or from others in progress, FCT Combustion is always open to working with industrial partners for evaluation and plant trials of new technologies to deliver the best solutions for our customers.
FCT ACTech’s RMX analyzer for raw mix control achieves excellent results
The first RMX analyzer for raw mix control was commissioned in December 2018 for a plant in Alabama, USA. RMX analyzes raw meal with elemental data updates every 2 minutes, with the real time data stream enabling frequent raw mix feeder adjustments in kiln feed LSF and C3S variation.
Since commissioning, the plant has reported excellent results achieved through the at-line installation of the RMX. Raw meal variation has been reduced by 44%, resulting in significant improvement to kiln feed variability, while clinker free lime variability has also been measurably reduced.
“The kiln operators report that the mix is easier to burn, and the kiln is easier to control,” a representative said.
“Before we had to target a lower C3S to assist with kiln operation, now we can target 63-64 and achieve higher early strengths.”
The RMX is part of FCT ACTech’s X-Series range which includes a suite of analyzers for raw mix, clinker quality and cement blends control, as well as elemental and mineralogical analyzers for the mining and mineral processing industries.
The X-Series range is the next generation evolution from the same patented technologies that propelled the Continuous On-Stream Mineralogical Analyzer (COSMA) to the forefront of process control technologies 20 years ago.

Case Study: Optimizing alternative fuel combustion and benefits
This is the first instalment of a two-part case study, which outlines the work undertaken by FCT Combustion to optimise combustion and increase the alternative fuel firing substitution rate at Cemmac’s Horne Srnie cement plant.
FCT was established more than 35 years ago to bring more science into the art of industrial combustion. Since then it has gained a reputation for technical excellence and introducing innovative and value adding technologies across high temperature processing industries.
Kiln and calciner burner systems have a major impact on the bottom-line results for a cement plant, and so customised optimisation of the flame for any given kiln is critical to get the best plant performance.
About the client
Cemmac is a cement producer located in Horne Srnie, Slovakia. The plant operates a 5-stage ILC kiln (3.4m x 46m long), which produces 1,200t/d of Portland clinker.
At the time of the study, coal and Residue Derived Fuel (RDF) were fired in the kiln by a 30MW burner from another supplier based in Europe. Additionally, two calciner burners from that same supplier were used to fire coal in the calciner. Tyres were also fed into the kiln inlet and RDF to the calciner at the twin tertiary air inlets.
Cemmac approached FCT Combustion as they wished to increase their alternative fuel substitution rate.
The rate of RDF firing in the calciner was limited to 20% substitution due to high CO levels, measured at the exit stage 4 cyclone (with stage 5 being the bottom stage) in excess of 0.3% or 3,000ppm. Even when firing 100% coal, the firing rate was limited by CO which in turn limited the degree of calcination and overall plant capacity (LOI of the stage 5 hot meal high at 8.4%).
Severe problems with build-up forming in the area above the kiln inlet chamber were also identified. To remove the build-up, the kiln was stopped for several hours roughly once every two weeks.
A process and combustion study of the kiln, as well as a more detailed Computational Fluid Dynamics (CFD) study of the calciner, were undertaken by FCT Combustion with the aims of:
- Improving coal combustion
- Improve RDF combustion
- Reduce CO levels in kiln inlet
- Increasing alternate fuel substitution
- Consider introducing a new alternative fuel, Polyurethane (PUR) dust, to the calciner
- Reducing build-up in the kiln system
- Improve operational stability
