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.
