Solid waste incineration process

Rotary kiln and stoker system can treat many kinds of waste such as plastic waste, sludge and so on.


  • Treatment of various kinds waste
  • Easy operation control
  • Effective utilization of residual waste heat recovery (steam, power generation, preheated air, dry heat sources etc.)
