How Hot is an Industrial Kiln? 4 Key Temperature Ranges You Should Know

Industrial kilns, particularly rotary kilns, can reach extremely high temperatures depending on their type and configuration.

How Hot is an Industrial Kiln? 4 Key Temperature Ranges You Should Know

How Hot is an Industrial Kiln? 4 Key Temperature Ranges You Should Know

1. Indirect Fired Rotary Kilns

Indirect fired rotary kilns have multiple and compartmentalized temperature control zones.

In some cases, such as graphite furnaces, these kilns can reach temperatures as high as 2,400 degrees Celsius (4,352 degrees Fahrenheit).

Indirect kilns can process materials at temperatures between 800 and 1,832 degrees Fahrenheit (430-1,000 degrees Celsius).

These kilns are commonly used for calcination, reduction, controlled oxidation, carburization, solid-state reactions, and purification processes that require extremely high temperatures and tight control.

2. Direct Rotary Kilns

Direct rotary kilns are the most efficient in terms of heat transfer.

They can process materials at temperatures between 800 and 2,372 degrees Fahrenheit (430-1,300 degrees Celsius).

In direct kilns, the process gas passes through the drum either co-currently or counter-currently to the material.

The drum is typically refractory lined and may contain lifting or tumbling flights to improve heat transfer.

The use of a combustion chamber depends on the material's sensitivity to heat.

Refractory lining is common in direct-fired kilns to protect the drum shell and promote better heat retention.

3. Temperature and Retention Time

In both types of rotary kilns, the temperature and retention time of the material being processed are predetermined based on chemical and thermal analysis.

The rotating drum is sealed to control the atmosphere and temperature inside the kiln to manage the intended reaction(s).

4. Overall Temperature Range

Overall, industrial kilns can reach temperatures ranging from 800 to 2,400 degrees Celsius (1,472 to 4,352 degrees Fahrenheit), depending on the specific kiln type, configuration, and application.
