Incinerating Hazardous Waste

Incineration:Hazardous Waste

Hazardous Wastes• Most industrial processes

produce waste, some of which can be hazardous and detrimental to public health and the environment if not managed properly.

• Hazardous wastes are generated in the production of cosmetics, detergents, pharmaceuticals, household paints and cleaning products, phones, televisions, garden pesticides, computers, gasoline and even light bulbs.

Many companies havemade significant progress in recent years to reduce or recycle hazardous wastes from their processes.

A variety of businessesgenerate hazardous waste, including dry cleaners, automobile repair shops, hospitals, exterminators and chemical manufacturers.

In the U.S., modernhazardous waste incineration is a widespread and common technology.

Incineration converts waste into ash, flue gas and heat. Ash is produced by the inorganic substances in the waste and may

appear as solid lumps or particulates carried by the flue gas. The flue gases can be dispersed into the atmosphere, but first they

must be cleaned of any gaseous and particulate pollutants.

Incineration

The kiln rotates slowlyto ensure that the solid wastes are exposed on all sides to the high temperature in the kiln.

Vulcan Systems

In the incineration process, hazardous waste is fed semi-continuously by a ram feeder. The ram feeder can be automatically or manually cycled through a

refractory line charging into the combustion chamber. The primary combustion chamber consists of the rotary drum and a 20 MMBtu burner

which is controlled and modulated by a temperature controller and temperature element placed in the ductwork between the primary and

secondary combustion chambers.

The Process

The vapor from theprimary combustion chamber is pulled through refractory lined ductwork to a secondary combustion chamber, where the vapor is oxidized at temperatures up to 2,600 degrees Fahrenheit for at least two seconds.

Prevents Pollution

• Incinerating hazardous waste decreases the load placed on landfills and prevents potentially dangerous materials within the waste from leaching out and polluting the surrounding environment.
