Rotary kiln incineration systems are ideal for processing mixed industrial and hazardous wastes that include a combination of solid, sludge, and liquid waste streams. Verantis provides complete rotary kiln incineration packages including a broad range of waste storage and feed systems (ram feeders, sludge feed systems, liquid injection systems), complete combustion system packages, and many different options for continuous ash removal. Rotary kiln incinerators can be paired with custom engineered air pollution control systems for a turnkey environmental solution.

When calcined white cement clinker, the pulverized coal burning in the rotary kiln should meet certain requirements, then can make the mature material into the clinker and obtain high production and quality.

1) Pulverized coal combustion flame temperature should reach above 1700 degress Celsius, then can ensure that white cement clinker can be made in 1500-1600 degrees Celsius. Due to all of the secondary air which pulverized coal burning in the white cement rotary kiln depend on the cold air which provide by the leakage at the part of burner hood, so the pulverized coal is burned slowly in the rotary kiln and is burned under the low flame temperature.

2) The flame which the pulverized coal burn in the rotary kiln should have a complete, appropriate to shorten and easy to adjust. It means that require the flame high temperature part is relatively concentrated, the black rotor is shorter, flame stability.

3) Pulverized coal in the rotary kiln should be completely combustion, in order to reduce heat loss produced by incomplete combustion. But in the kiln should not appear excessive oxidation atmosphere.
