Hazardous Waste Incineration Systems

Incineration Systems

Hazardous Waste has listed it in one of three categories:

  • Source-Specific Waste: This list includes waste from specific industries such as petroleum refining, wood preserving and secondary lead smelting, as well as sludge and production processes from these industries,
  • Generic Waste: This list identifies waste from common manufacturing and industrial processes including spent solvents, degreasing operations, leachate from landfills and ink formulation waste,
  • Commercial Chemical Products: This list includes some pesticides, creosote and other commercial chemicals

Working Principle

Hazardous wastes can be in the form of liquid, solid, gas, or sludge. They can be discarded commercial products, like cleaning fluids or pesticides, or the by-products of manufacturing processes.

All hazardous waste in the form of solid, liquid, gas and sludge can be destroyed by Santes Incineration system.

To achieve individual charging of liquid wastes, incineration system is equipped with a liquid injection system through which liquid charging to the combustion chamber is achieved. Flow is given to the system via two spray nozzles namely double fluid atomizers. Double fluid atomizers are used to get very fine droplets in order to get better incineration efficiency.

Hazardous Waste Incinerators has two combustion chambers. In the main combustion chamber wastes are incinerated in 900 oC with the principle of starved air incineration and the flue gas originated in this chamber is directed to the secondary combustion chamber. In the secondary combustion gases formed during the incineration of wastes in the main combustion chamber are re-burnt at 1200 °C during 2 seconds. Excess air is provided to the secondary combustion chamber to achieve complete combustion of organic content of the waste.

Hazardous waste has high calorific value so it can be used as a source of energy. Therefore, in the incineration process, it requires less fuel to increase its temperature to 1200 oC. Waste energy most often recovered as steam can be used to generate electricity.

There are two main Regulations for the Hazardous Waste Incineration Systems in the world; namely, EPA and EU 2000/76/EC. Şantes Incinerators can be designed fully in compliance with both of these regulations as well as the local standards.

In order to be fully in compliance with the desired Emission Standards, Şantes Incineration Systems Includes flue gas treatment units. Flue Gas Treatment in these systems is multi pollutant control approach to remove the hazardous content of combustion gas originated due waste incineration

Advantages of Santes Incinerator for Hazardous Waste;

  • Hazardous waste incineration method is suitable for a wide range of hazardous wastes such as highly flammable, volatile, toxic and infectious waste streams which should not be landfilled
  • Santes Incinerators designed to be fully in compliance with desired emission standards,
  • Moisture content causes no problem,
  • Produces clean ash in small volumes,
  • Produces no dioxins even with added chlorine,
  • Product gas has a much higher heating value,
  • Feed contaminants, such as chlorine & sulfur, are reduced to their acid forms
  • Possibility of energy recovery
