Indirect-fired Rotary Kiln In Your Rotary Kiln Business

Indirect rotary kiln has become a more common commercial option in the past 25 years. Indirect rotary kiln differs from direct combustion in that all heat transferred to the processing material is radiated through the casing meanwhile the construction material can withstand higher temperatures. The indirect rotary kiln is horizontal.

The gasifier is a rotary kiln with a 6 degree angle of inclination. Unlike a traditional rotary kiln, it is divided into three regions, which are oxidative degradation, partial oxidation and char gasification. Biomass is fed into the reactor from the left end and passes through the gasifier by rotating the reactor.
