Calcining Furnaces

Tenova has developed advanced technologies for petroleum coke and coal rotary hearth calciners used to process lignite, sub-bituminous coal, anthracite, brown coal, formed coke briquettes and many other carbon-based products.

Its proprietary rotary hearth calciner provides better product quality and higher product yield than traditional rotary kilns.

Tenova is a worldwide leader in the supply of loose carbonaceous material calciners based on rotary hearth technology. These furnaces are used for the processing of lignite, sub-bituminuous coal, anthracite, brown coal, petroleum coke, formed coke briquettes and various other carbon based products. We design and supply rotary hearth furnaces that provide a higher quality product than typical rotary kilns. The advantages over traditional kiln technology include:

  • Higher fixed carbon recovery due to less burnout and less carryover
  • Lower fuel usage
  • Lower pollution emissions
  • Consistent coke quality
  • Lower refractory maintenance cost
  • More flexible operation
  • More visible operation
  • Less degradation of the material granules due to the gentler processing of the material.

Our calcining technology includes features such as:

  • Hot recovery of escaped particles in waste gases
  • Waste gas incineration
  • Waste heat recovery
  • Sealed discharge systems
  • Cooling systems

Additionally, Tenova also supplies a rotary hearth based unit for drying of coal products.
