The rotary kiln equips flexible seal (the wear-resistant coating on the rotary kiln drum body is in contact with a high-temperature and wear-resistant surface fixed on elastic heat-resistant steel; the middle layer uses carbon-silicon-nickel composite sealing plates, and the outer protective layer is SUS304, with graphite self-lubricating blocks on the contact surface with the rotary kiln). Long service life, good sealing performance, and <1% low air leakage rate are guaranteed.

The rotary kiln applies a combination burner (fuel + waste liquid + primary air supplementation). Its adjustment control valves and instruments are from top-tier suppliers. Compact structure, space-saving; multi-component waste handling, separated control, automatic ignition, automatic flame monitoring, extinguishing protection, fault alarm, etc.; high flame intensity, stable combustion, good safety, and wide power adjustment range.

Primary air supplementation enters the rotary kiln through the combination burner and the outer side of the inlet chute’s water-cooling wall. This preheats the primary air while protecting the burner, thus to improve thermal efficiency. The primary air supplementation adopts a special swirl structure, which allows for full contact with the materials.
