Commissioning of the 110m long horizontal kiln had a number of challenges, including adjustment of the Burner Management System (BMS) Air/Fuel ratio to produce a perfect flame pattern and efficient heat transfer to the product. The wet magnetite (Vanadium/Iron/Titanium) concentrate travels towards the flame, propelled by the rotation of the kiln. The product is cooled as it exits the kiln via heat recovery chambers to improve the energy efficiency. The final product is then cooled, dried and reduced in a DC Arc Furnace to produce Ferro-Vanadium ingots.
This photo shows the horizontal kiln, which is seated on rollers which are designed to allow for expansion of the steel frame. Multiple temperature sensors built into the structure measure the product as it flows towards the hot end of the kiln. The exhaust gas is filtered to remove dust, and a small negative pressure is maintained at the product feed chute at all times to prevent flameout.
In 2019, Logitech Engineering assisted Gasco to design and construct a new Thermal Oxidiser for the QAL Alumina Refinery in Gladstone QLD. The purpose of the Oxidiser is to destroy all odours and volatile components which are released from the Bayer process, including Hydrogen, which are burned at over 900 degrees. The AGA certified BMS burner has a design life of 30 years, and requires only a 3-day shutdown each year to maintain.
Pharmaceutical and Food Processing Industries rely heavily on local control panels and operator interfaces that are IP66 rated, so that they can be hosed down without risk of damage to the equipment. Logitech Engineering design and fabricate weather-proof, sanitary, explosion proof, and even fire-proof control panels and operator stations. We can design and fabricate pendant and joystick controls, and local control stations to suit any application, including underground and hazardous areas.
