South Korea/Thailand: Austria’s Unitherm Cemcon has commissioned a MAS kiln burner at a cement plant in South Korea. The order was issued in late 2018 for three MAS burners. The first burner was delivered in February 2019 and the other two in March 2019. In May 2019 Unitherm Cemcon says it supported the commissioning of the first burner.

The scope of supply included two 43MW MAS/4/KO SO type burners for coal and heavy oil and one 87MW MAS/7/KO SO.X type rotary kiln burner for coal, heavy oil and solid secondary fuels. All three burners have been executed with a divisible burner jacket tube. One MAS/7/KO.SO.X is already successfully operating in another line, firing up to 6t/hr of coal and around 10t/hr of solid secondary fuel.

The burner manufacturer has also been awarded a contract to supply a hot gas generator for a plant in Thailand. The scope of supply includes: engineering and manufacturing drawings for the hot gas generator combustion chamber; a combined 45MW oil and coal burner; a primary air fan; a gas electric pilot burner; a flame monitoring device; and an oil valve train with burner management system.

Austria: Unitherm Cemcon has launched the MAS DT rotary kiln burner, a new product in its Mono Airduct System (MAS) product line. The new burner is already in operation at six cement plants in Austria, Germany and France.

The new design uses a more efficient primary air injection, resulting in higher effective momentum and optimised combustion. Placing the adjustable primary air openings directly at the burner tip leads to unobstructed injection of the air jets into the kiln. With minimum losses at the air nozzles, the entrainment of secondary air is improved by approximately 15%.

The new primary air system, with discs instead of flexible hoses, requires less space inside the primary air channel. Therefore, the burner is smaller in diameter and lighter in weight, which reduces investment costs. Unitherm Cemcon says that the cooling of the outer jacket tube with the MAS system (hose and disc design) is superior to that of other rotary kiln burners, as 100% of the primary air is used for cooling. With the new disc system, the cooling of the burner tip is improved even further. The producer added that all new MAS DT burners showed improved lifetime of the refractory lining at the burner. On average the refractory lifetime is extended by approximately 20%.

World: FCT Combustion has released details on new burner projects it is involved with. Selected projects include a new contract in the US to convert both kilns to natural gas firing at Ash Grove Cement’s Louisville plant in Nebraska. The order includes Gyro-Therm MKII Burners, Natural Valve Trains and NFPA 86 BMS for both kilns.

Nova Cimangola in Angola has contracted FCT to convert its 5000t/day kiln to fuel oil firing. The order includes a multi fuel main burner, calciner burners, oil heating units, oil pumping and filtering units and control panels.

FCT also provided details about a low NO_x kiln conversion for an undisclosed client. Other selected cement sector projects include the commissioning of Turbu-Flex burner systems for clinker kilns at Finnsementti’s Parainen and Lappeenranta plants in Finland. These are scheduled for commissioning in March 2019 and April 2019 respectively. Baumit’s Wopfing plant in Austria is due for a natural has lance for kiln preheating to be delivered later in March 2019.

It also plans to deliver a Turbu-Flex burner system for a clinker kiln to an undisclosed client in China later in March 2019. It is based on a computational fluid dynamics (CFD) study undertaken by FCT is to allow for the firing of natural gas and to modernise the plant. Commissioning is scheduled for March 2019.

Trinidad: Austria’s Unitherm Cemcon has been awarded the contract for a rotary kiln burner for kiln 3 at Trinidad Cement’s 1230t/day plant. The burner for the wet process unit will be designed for natural gas and liquid alternative fuel. No value for the order has been disclosed.

The scope of supply includes: one MAS/5/EGSO model rotary kiln burner; a flame monitoring device for the rotary kiln burner; a gas electric ignition burner with control box and touch screen; kiln burner trolley engineering and main components for local manufacturing; primary air fan with sound protection housing; and an emergency cooling air fan.

Other recent projects from Unitherm Cemcon include the commissioning of a firing system for BUA Cement’s new plant in Edo State, Nigeria and delivery of firing equipment for a project in Argentina in late 2018.

UAE: Lafarge Emirates has ordered a Jetflex Plus burner for its Fujairah cement plant from FLSmidth. Thierry Terriere, the plant manager, and Simon Jensen, head of FLSmidth Middle-East, signed the contract.

“As the business has shifted towards using low-cost fuels with high-quality clinker, we have made an ambitious decision and chosen the best option on the market – this next generation burner from FLSmidth," Sohail Qaiser, Process Manager at Lafarge Emirates Cement. He added that the company expects a ‘significant’ change in its fuel mix cost as well as a more sustainable kiln operation.

FLSmidth says that the Jetflex Plus burner is the first to be installed in the LafargeHolcim Group and that the company was selected for procurement and supervision of the installation of it. The burner product has rotatable jet air nozzles allowing for optimal adjustment of the flame as well as the low NOx emissions for various fuel types and operating conditions.

The relationship between the companies dates back to 2007 when FLSmidth built the 7500t/day Fujairah plant for Orascom.

Brazil/US/Vietnam: FCT Combustion has released details on new burner projects it is involved with. Selected projects include the commissioning of Gyro-Therm burners for Kilns 1 and 2 for use with natural gas, coal, petcoke and solid alternative fuels at Lehigh Cement’s Evansville plant in Pennnsylvania in the US. The supply also included the burner management system, valve trains, fans and other accessories.

The company is also working on an upgrade to the hot gas generator at Votorantim Cimentos’ Vidal Ramos plant in Santa Catarina, Brazil. Also in this country it is supplying Turbu-Jet AF burners with blowers, ignition and flame detection systems to CSN Cimentos’ Arcos plant in Minas Gerais.

Finally, in Vietnam the burner supplier is to provide a Turbu-Jet AF burner firing low calorific value coal with fuel oil to Vinacomin’s Quan Trieu Cement plant.

Australia: FCT Combustion plans to launch its Turbu-Flex burner in April 2018. The pyro-processing engineering company says that the product will enable operators to switch between different fuels and optimise for each with the one burner. Switching between alternative and refuse derived fuels is intended to allow cement and other industrial plants to lower fuel costs and improve kiln performance. The burner also offers reduced maintenance, as it no moving parts are needed to change the air supply.

“We’ve now proven the burner’s benefits and ease of use in the field. Under testing for almost one year, and operating with over 80% fuel replacement using refuse-derived fuel (RDF), the results are very pleasing for the plant operator and FCT,” said Con Manias, the Managing Director of FCT International. He added that the company also focused on building its footprint in South East Asia.

The company says that it has projects running in six continents due to a ‘surge’ in burner orders. FCT Combustion is currently working on projects in the US, Canada, Brazil, Ecuador, Poland, France, Egypt, Belgium, Italy, China, Thailand, Malaysia, Algeria, Oman, Belgium, France, Ukraine, Turkey and Australia.
