There have been a few burner and related stories to note in the cement industry news this week. Firstly, Canada-based PyroGenesis announced that it had signed a deal with an unnamed-European cement company to supply a plasma torch system for a ‘calcination furnace.’ Around the same time UBE Mitsubishi Cement (MUCC) revealed that it had successfully tested natural gas co-firing at MUCC’s Kyushu Plant using a newly developed burner.

The PyroGenesis project is a potential game-changer for the sector because it alters the way cement production lines are heated. Roughly one third of CO₂ emissions associated with cement manufacture arise from the fossil fuels used to heat the kiln and the pre-calcination system. Cut out some of that and the specific CO₂ emissions of cement production drop. PyroGenesis’ approach uses electricity to generate high-temperature plasma. This then gives the cement plant the option of obtaining its electricity from renewable sources. PyroGenesis signed a memorandum of understanding with the power conversion division of GE Vernova in March 2025. This had the aim of targeting high temperature processes, such as cement production, with electric plasma torches. The current deal with a cement producer has been valued at US$871,000 with delivery to the client scheduled for the first quarter of 2026.

We don’t know who the mystery client might be. However, Heidelberg Materials reportedly operated a 300kW plasma-heated cement kiln at its Slite cement plant in February 2025 as part of the ELECTRA project. The producer said it had achieved 54 hours of continuous operation, with 60% CO₂ concentration in the flue gas. The aim was to reach 99%. It then said that it was planning to build a larger 1MWel furnace at its Skövde cement plant in 2026 with tests to continue in 2027. In an interview with Global Cement Magazine in May 2025, Heidelberg Materials said that it was using commercially supplied CO₂ as the ionising gas in the plasma generator but that it was considering using captured CO₂ from the production process in the future. It also mentioned issues from its trials such as the effective ‘flame’ being hotter than the conventional process but not as long. This increased the reactivity of the resulting clinker. Finally, Heidelberg Materials noted from a feasibility study that a 1Mt/yr cement plant would need around 170MW of plasma generation, but that typical plasma generators topped out at around 8MW. Hence, any full set-up would likely require multiple plasma generators. For more on non-combustion style kilns see GCW561.

UBE Mitsubishi Cement’s burner installation is more conventional but again it is concerned about sustainability. In this case the line has tested burning natural gas. The cement producer says it is the first such installation at a cement plant in Japan to do so commercially. The burner was jointly developed by UBE Mitsubishi Cement, Osaka Gas and Daigas Energy. Firstly, the plant will consider switching to natural gas. This will reduce the unit’s CO₂ emissions from fuel combustion. However, a later step being considered is to move on to e-methane. This is a synthetic methane made from CO₂ and hydrogen using renewable energy.

Finally, another recent story on this theme is the installation of a new satellite burner by Northern Ireland-based Mannok at its Derrylin cement plant in August 2025. This is Phase One of a two-part project to upgrade the pyro kiln system at the site. The cement company worked with FLSmidth on the €2.5m upgrade. The new burner has now allowed the plant to burn solid recovered fuel (SRF) by up to a 30% substitution rate in the kiln. This followed a project, also with FLSmidth, to install a FuelFlex Pyrolyzer in 2022. This is used to replace coal with SRF in the pre-calcination stage of cement production. Phase two will be an upgrade of the main burner to a new Jetflex burner. Once this part is completed, Mannok is aiming for an overall substitution rate of 65 - 70% on the whole pyro-processing system.

Burners at cement plants are replaced fairly commonly. However, the supplier companies don’t advertise every installation due to the commercial relationships with their clients and other factors. Hence the more interesting upgrades tend to get the publicity. Typically this means if a burner uses new technology, meets sustainability goals and so on, we find out about it. It’s a similar situation when a new heating technology such as plasma is trialled. Changing trends in fuel types for cement plants suggest different types of conventional burners. Some of this can be seen in the burner stories above with the trend moving towards ever higher rates of alternative fuels usage. Combustion in cement kilns is here to stay for the time being but plasma trials will be watched carefully.

The 18th Global CemFuels Conference & Exhibition on alternative fuels for cement and lime 2025 will take place in Milan on 17 - 18 September 2025

Ireland/UK: Mannok has completed Phase 1 of a two-phase upgrade to its pyroprocessing system with the installation of a new satellite burner in collaboration with FLSmidth. The €2.5m project enables the use of solid recovered fuel (SRF) as a replacement for coal, achieving up to 30% substitution and reducing CO₂ emissions by 23,000t/yr.

Phase 2 will involve upgrading the main burner to a Jetflex system, targeting 65–70% coal substitution across the kiln. Mannok produces about 1.4Mt/yr of cement for customers across the UK and Ireland.

Japan: Mitsubishi UBE Cement Corporation (MUCC), Osaka Gas, Daigas Energy and Saibu Gas have successfully tested natural gas co-firing at MUCC’s Kyushu Plant in the Kurosaki area. Using a newly developed burner, the companies replaced 40% of coal with natural gas at commercial scale without affecting kiln stability, product quality or environmental performance.

The burner was developed using MUCC’s coal combustion expertise alongside Osaka Gas and Daigas Energy’s gas combustion and simulation technologies, with Saibu Gas supplying natural gas from LNG tank trucks. MUCC said the trial paves the way for full-scale implementation and supports future use of e-methane in cement kilns.

MUCC aims to cut CO₂ emissions by 40% by 2030, compared to 2013 levels, and achieve group-wide carbon neutrality by 2050 under its medium-term management strategy “Infinity with Will 2025 – MUCC Sustainable Plan 1st STEP.”

Romania: Holcim Romania has successfully upgraded pyroprocessing and cement grinding equipment at its Câmpulung cement plant in Argeș County. Germany-based KHD Humboldt Wedag supplied equipment for the upgrade. For the plant’s pyroprocessing line, this included a downcomer duct, water injection system and induced draught fan, as well as an upgrade to the clinker cooler. Meanwhile, the grinding line has received a new SKS Z 2500 dynamic separator, cyclones, process ducts and separator fan. The supplier says that the upgrade has increased the Câmpulung plant’s clinker capacity and the efficiency of its operations. The work took 14 months to complete from the signing of the contract in mid-2023.

North Korea: State-owned Cheonnaeri Cement has completed a successful upgrade to its 1Mt/yr Cheonae cement plant in South Hamgyong Province. Korean News has reported that the upgrade involved the replacement of the plant's clinker cooler, burners and clinker and raw materials handling systems. A new bucket conveyor has more than doubled raw materials handling capacity.

Cheonnaeri Cement reportedly plans to further expand the capacity of the plant.

Uzbekistan: Bekabadcement is carrying out a 'large-scale' upgrade to its 0.7Mt/yr Bekabadcement plant in Tashkent Region. The producer said that the upgrade involves a 20% capacity expansion of the plant's production line to 2500t/day. Austria-based Unitherm CemCon supplied burners for the upgraded line, while China-based Beijing Triumph International Engineering supplied heat exchanger components and a KC 4.1-0955 cooler. The upgrade also involves the installation of new kiln lining, and will transition the plant's cement production from wet to dry process. Germany-based Christian Pfeiffer previously upgraded the Bekabad cement plant's grinding unit in April 2023.

General director Vasily Korobkin "We see that (parent company) United Cement Group (UCG) is interested in the modernisation and development of the enterprise. The group adheres to international standards, so all plans for the development of the plant are built accordingly." He concluded "We expect to become a modern and successful enterprise in Uzbekistan which is capable of becoming a major player in the cement industry of Central Asia.”

Finland: Finnsementti is carrying out upgrades to its two integrated cement plants as part of its sustainability targets to 2030. The subsidiary of Ireland-based CRH is installing new main burner equipment at its Lappeenranta plant with completion scheduled for mid-2023. The project is intended to allow the plant to increase its use of alternative fuels. The company’s Parainen plant is replacing its satellite coolers with a grate cooler with completion scheduled for the spring of 2024. This work is expected to decrease the plant’s emissions by 10%. Overall the group is preparing to decrease its CO₂ emissions by 30% by 2030 compared to 2021 levels.

Vietnam: ThyssenKrupp Polysius’ Asia Pacific division has secured an order for two Polflame-type main burners for an unnamed cement plant. The equipment supplier has highlighted the ability of its burner product to cope with low-grade coal and support high alternative fuel substitution rates as key selling factors. The order follows the purchase of an Impact Crusher by the same customer previously.

Lukas Schoeneck, the chief executive officer of Polysius Asia Pacific, said "We are very proud to add burners number 17 and 18 to our installed base in Vietnam which ensures our market leader position. Now we have to put our focus on the delivery and installation of the burner - in time and quality.”
