What is rotary kiln incinerator?

What is rotary kiln incinerator?

Rotary kiln incinerators are cylindrical, refractory-lined steel shells supported by two or more steel trundles that ride on rollers, allowing the kiln to rotate on its horizontal axis. The refractory lining is resistant to corrosion from the acid gases generated during the incineration process.

What are the types of incinerator?

The following are types of incinerators


What is a rotary kiln used for?

A rotary kiln is a pyro-processing device that raises materials to very high temperatures in a continuous process. It is used to create cement, lime, metakaolin, titanium dioxide, alumina, iron ore pellets, and more.

What is liquid injection incinerator?

Liquid injection incinerators are used to dispose of aqueous and nonaqueous wastes that can be atomized through a burner nozzle. Liquid wastes, sludges, or slurries that contain large amounts of solids must be filtered before they are stored in feed tanks that are usually pressurized with nitrogen.

How does a rotary kiln incinerator work?

The rotary kiln incinerator is manufactured with a rotating combustion chamber that keeps waste moving, thereby allowing it to vaporize for easier burning. Types of waste treated in a rotary kiln incinerator. Photo: a rotary kiln and a section view. Hazardous waste and PCB waste.

What kind of incinerator is used for non hazardous waste?

A cement kiln incinerator is an option that can be used to incinerate most hazardous and non-hazardous wastes. The rotary kiln type is the typical furnace used in all cement factories. Rotary kilns used in the cement industry are much larger in diameter and longer in length than the previously discussed incinerator.

Can a rotary kiln be used for hazardous waste?

Read here more about the different types of rotary kiln. Can handle batch modes like barrels and allows more flexibility than continious modes Note: The rotary kiln incinerator for medical and hazardous waste is operating 24h per day and 7500 h/year.

What are the dimensions of a rotary kiln?

Rotary kiln incinerators usually have a length-to-diameter (L/D) ratio between 2 and 8. Rotational speeds range between 0.5 and 2.5 cm/s, depending on the kiln periphery. High L/D ratios and slower rotational speeds are used for wastes requiring longer residence times. The kilns range from 2 to 5 meters in diameter and 8 to 40 meters in length.
