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.
