Horizontal Kilns
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.
Burner Management
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.
Thermal Oxidisers
In 2020, Logitech Engineering assisted Gasco to design and construct a new Thermal Oxidiser for the Queensland Alumina Refinery (QAL) in Gladstone. The purpose of the Oxidiser is to destroy all odours, hydrogen gas and volatile components which are released from the Bayer process, which are burned at over 900 degrees. This AGA certified Class B appliance has a design life of 30 years, and requires only a 3-day shutdown each year to maintain.
An enhanced liquid injection system was added to the oxidiser using compressed air to atomise the liquid. This air flow also keeps the lance cool to prevent damage to the burner tip, and to prevent blockages occuring inside the injection assembly.
Specialised Panels
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.
