A green transition does not need to be complex and costly. When burners are designed to utilize a wide variety of fuels and industrial side streams, it is possible to significantly improve the plant’s environmental efficiency from the next shutdown onwards, says international technology major Andritz AG.
Today, burners also play a major environmental role as many industries switch to renewable fuels, and they are often installed to handle side-streams from production processes.
Efficient combustion requires advanced burner solutions
International technology group major Andritz AG develops, designs, and installs tailor-made burner systems capable of combusting almost any fuel available, which is appealing for any industry or company looking to transition from fossil fuels.
We have a great team designing and tailor-making burners to suit a wide variety of applications. These burner solutions are vital to our projects related to reducing odour emissions at pulp mills, and to reducing carbon emissions by performing a fuel conversion to biofuels, said Lauri Tuominen, Director Recovery and Power Side Streams Services at ANDRITZ.
The company provides the whole range of burner systems across many industries, including pulp and paper, energy, metallurgy, and process industries.
With a deep understanding of the customer processes and the ability to deliver bespoke burner solutions, including erection, piping, pressure pipe modification, and automation, ANDRITZ sets itself apart from other suppliers.
When customers have very demanding and harsh process conditions, we ensure our equipment is the perfect fit for their needs. We can achieve fuel flexibility without needing to carry out significant modifications to the main process. In addition, we can assist customers in the introduction of side streams to bring additional value to their mills and plants, said Perttu Jukola, Product Director, Burners at ANDRITZ.
Sustainable fuels – significant benefits to customers
As well as burner systems for boilers in pulp, paper, and energy, ANDRITZ supplies burner solutions designed to utilize industrial side streams, biofuels, and other sustainable fuels.
Generating green energy results in the reduction of carbon dioxide (CO2) at mills and plants.
Even streams previously considered as waste can be processed to produce valuable chemicals and raw materials instead of going for incineration.
The use of side streams has become an important area of focus at pulp mills, in particular, as they are being rapidly transformed into biorefineries. This is due to the ability of these mills to recover chemicals and biofuels from the pulping process. This has a number of financial benefits to our customers as it means they can avoid emission penalties set by the regulators, as well as use recovered side streams in internal processes, said Perttu Jukola.
Examples of such implementations in the pulp and paper industry include gathering concentrated non-condensable gases (CNCGs) and combusting them with burners installed in ANDRITZ SulfoLoop plants to produce sulfuric acid; using methanol and turpentine recovered from the pulping process to fire recovery boilers and lime kilns – also supplied by the company; or utilizing powdered wood from woodyard waste to power the lime kiln by installing an ANDRITZ LimeBio-Powder lime kiln biofuel plant.
‘EnviroBurner’ multifuel solutions
With over 250 references of its multi-fuel burners worldwide, ANDRITZ’s vast experience in burner technologies provides pulp and paper operators and energy companies with a considerable range of options for burning almost any fuels available, including waste streams.
There are many benefits our customers can take advantage of when utilizing side streams across mills, including new products, fuel savings, and efficiencies, as well as reducing CO2 emissions. ANDRITZ can supply complete burner solutions across mills and energy plants to ensure our customers have the very best in sustainable solutions, said Perttu Jukkola.
Furthermore, the company offers a complete burner replacement service for existing boilers at mills and energy plants by installing the latest technology to improve performance.
Simply replacing older burner technology in existing mills and plants can make a huge difference to the availability of processes when it comes to start-up times and efficient operability. With burner upgrades, we can increase availability from below 90 percent up to 99 percent with the installation of our latest burner technology, and it can be completed during a normal planned shutdown, concluded Lauri Tuominen.
