Overview

Incineration is a process of burning hazardous materials in a specially designed furnace called an incinerator. It destroys contaminants by subjecting the materials to high temperatures for a specific duration. Incinerators can treat various types of hazardous materials, but they do not destroy metals. The process involves heating the materials in the combustion chamber, where contaminants volatilize and are destroyed. Gases that remain pass through a secondary combustion chamber and then go through air pollution control equipment. Ash leftover from the combustion process may require disposal in a hazardous waste landfill. The cleanup time for incineration varies depending on factors such as the amount and nature of the waste. Properly designed and operated incinerators can safely destroy harmful chemicals, and precautions are taken to prevent the release of hazardous materials during transportation. Incineration is chosen for its ability to effectively destroy highly contaminated waste and reduce the amount of material that needs to be disposed of in landfills.

Technologies

• Rotary Kiln Incinerators

These incinerators use a rotating cylindrical chamber to combust waste. The waste is fed into the kiln at one end, and as it rotates, it is exposed to high temperatures, allowing for complete combustion. Rotary kiln incinerators are versatile and can handle a wide range of waste types.

Martin GmbH specializes in the design and construction or rotary incineration systems. Customized solutions for the incineration of various waste types, including hazardous and industrial waste.

• Fluidized Bed Incinerators

In fluidized bed incinerators, the waste is suspended on a bed of sand or other inert material and combusted at high temperatures. The fluidized bed provides efficient mixing and combustion, ensuring complete destruction of contaminants.

Babcock & Wilcox (B&W) offers BFB boilers that provide the flexibility to burn a wide range of fuels individually or in combination. This flexibility allows owners to take advantage of different fuel sources and control fuel costs. B&W’s BFB boilers are designed with reliability in mind, incorporating features such as open bottom design for easy removal of material, water-cooled gas-tight lower furnace for preventing gas leaks, and bottom-supported hoppers to reduce maintenance costs and mechanical stresses.

• Multiple Hearth Incinerators

Multiple hearth incinerators consist of a series of stacked hearths, and waste is progressively moved from one hearth to another. As the waste descends through the hearths, it is exposed to increasing temperatures, ensuring thorough combustion. Multiple hearth incinerators are often used for solid waste incineration.

Keppel Seghers, subsidiary of Keppel Corporation, specializes in Waste-to-Energy solutions. Offering multiple hearth incinerators as part of their waste treatment and energy recovery systems. Their incinerators are designed to optimize combustion efficiency and reduce environmental impact.

• Modular Incinerators

Modular incinerators are pre-fabricated units that can be quickly assembled and installed at the waste generation site. These incinerators offer flexibility and mobility, allowing for on-site treatment of waste without the need for transportation.

Inciner8 Limited is a company that manufactures and supplies modular/mobile incinerators for various waste management applications. Their modular incinerators are designed to be compact, efficient, and easy to install and operate.

• Liquid Injection Incinerators

Liquid injection incinerators are specifically designed to handle liquid wastes. The waste is injected into a high-temperature combustion chamber, where it is rapidly vaporized and combusted. This technology is commonly used for the treatment of liquid hazardous waste.

Fluidyne Corporation specializes in wastewater treatment and advanced oxidation processes. Offering liquid waste treatment solutions that incorporate liquid injection incineration technology. Their systems are designed to handle a variety of liquid waste types, ensuring efficient destruction of contaminant and compliance with regulatory requirements.
