Successful completion of the great challenge of retrofit and commissioning of this impressive 28 MW multi-fuel burner\u00a0#WTS<\/a>\u00a0for one of the most important timber companies in the world at its plant in Ponta Grossa,\u00a0#Brasil<\/a>. This burner is installed in a huge combustion chamber about 20m long, which supplies a 17 MW boiler and 2 dryers located quite downstream of the process. As fuels, Natural Gas and Wood Dust,\u00a0#P\u00f3<\/a>, residual from the production process of the plant are used.<\/p>\n

The peculiarity of this P\u00f3 (wood dust), makes it unfeasible to burn from scratch, always needing a stable gas flame to ensure the quality of the P\u00f3 flame. That is, in order to burn the P\u00f3, you must previously be burning Natural Gas, reach the desired \/ necessary temperature in the chamber, about 850 \u00baC, and finally, carry out the fuel change in a controlled manner and without turning off the burner. This is known as “Change On the Fly –\u00a0#COF<\/a>“, and it is one of the most impressive functions included in our\u00a0#Mk8<\/a>\u00a0controller.<\/p>\n

Due to the complexity of the production process, the\u00a0#DCS<\/a>\u00a0of the plant and depending on various values of temperatures, pressures, steam flows and material load in the dryers, is responsible for externally modulating our\u00a0#Mk8<\/a>, delegating to us the safety and efficiency of combustion. This security is achieved thanks to the implementation of 3 UV flame detectors and one IR, all of high sensitivity and working in parallel; and position feedback from the gas servo motor and from the PO feed screw.<\/p>\n

In addition to this, 2 more servo motors are available for the control of secondary and tertiary air to the burner, which ensures efficiency along with fuel control. The project also includes a\u00a0#EGAMk8<\/a>\u00a0Gas Analyzer and a\u00a0#DTI<\/a>\u00a0for real-time remote control from your control room. During the last days, various trainings of plant personnel were carried out both at the foot of the boiler and from the remote control room.<\/p>\n

From here, I would like to thank\u00a0Stephen Huggett<\/a>\u00a0enormously for their teachings and sense of humor during the long working days, the guys from\u00a0Santec Engenharia Industrial<\/a>\u00a0for their great work prior to and during the start-up, and the\u00a0Autoflame Engineering Limited<\/a>\u00a0team for their great remote support.\u00a0Cristiano Almeida Santos<\/a>\u00a0Creando de Almeida<\/a>\u00a0Chesterton Lima<\/a>\u00a0Marcos Paulo<\/a>\u00a0Steve Kemp<\/a>\u00a0Nadeem Iqbal<\/a>\u00a0Tom Garrett<\/a>\u00a0Zeyad Dujayli\u00a0<\/a>\u00a0 – Guillermo Ceba, Technical Account Manager for LATAM.<\/p>\n\n\t\t
