Performance of High-temperature Slagging Rotary Kiln

2018-6-7  Slagging Rotary Kiln Process The slagging, high-temperature process was born in Eu-rope about two decades ago, largely out of a necessity to destroy steel containers (usually steel drums) by melting them inside the rotary kiln in a pool of molten material (slag). The slag is discharged into a water filled quench and

SLAGGING ROTARY KILN INCINERATOR P2 InfoHouse

2018-6-13  SLAGGING ROTARY KILN INCINERATOR (Abstract) The rotary kiln is a horizontal cylinder, lined with refractory, which turns about its longitudinal axis. Waste is deposited in the kiln at one end and the waste burns out to an ash by the time it reaches the other end. Kiln rotation speed varies in the range of 0.05~0.5 revolutions per minute.

1996-9-26  Gas and bed temperatures were studied in a 4.4 m by 12 m, co-current flow, slagging rotary kiln at a commercial hazardous waste incinerator. The visual observations used by the kiln operators to control the process are described. These observations were quantified using thermocouples, radiation pyrometers, and phase-change indicators. The objectives were to estimate the peak bed temperature
