The container-based incineration system is designed for the incineration of solid, pasteous and liquid hazardous waste such as waste oil, organic solvents, paint sludge, lacquers, plastic, synthetic material, rubber halogenated waste, pesticides, PCB, hospital waste and infectious waste (optional).

The capacity of the plants is 2,000-4,000 tons per year, depending on the bulk density and the heat value of the waste.
The incinerator is a turnkey installation consisting of one 20-foot and two standard 40- foot containers thereby simplifying transportation and installation on site. The containerbased concept makes it very easy to move the system from one site with hazardous waste to another site. The system is complete with feeding system, rotary kiln, secondary combustion chamber, flue gas cooling system, flue gas cleaning, electrical wiring, control system, etc.

The operating temperature of the rotary kiln is 1,100C and the subsequent secondary combustion chamber ensures destruction of the organic components at a residence time of 2 seconds at 1,100C. The flue gas cooling system consists of a quench in which the flue gas is cooled by water evaporation before entering a heat recovery boiler. The boiler produces hot water, which can be utilised in several ways, for example for district heating.

The flue gas cleaning system is equipped with a bag filter, quench and wet scrubber, which ensures compliance with the following emission requirements as specified in EU directive 94/67/EC on the incineration of hazardous waste:

Dust: 10 mg/Nm3
Hydrogen Chloride, HCl: 10 mg/Nm3
Hydrogen Fluoride, HF: 1 mg/Nm3
Sulphur Dioxide, SO2: 50 mg/Nm3Carbon onoxide, CO: 50 mg/Nm3
Total Organic Carbon, TOC: 10 mg/Nm3
Dioxin: 0.1 ng/Nm3

The waste water from the flue gas cleaning system can be treated in a separate wastewater treatment plant if there is no direct access to a municipal waste-water treatment plant. A programmed logistic controller (PLC) ensures a fully automatically controlled operation.

Site requirements
For the container-based incineration system, a paved area of only 350 sq .m. is required. At the site the following consumables must be available:

Water Support fuel (Fuel oil or gas)
Electricity (380V, 3 phase, 50 Hz)
Air (Pressurised and instrument air)
Chemicals for fuel gas cleaning(Sodium hydroxide, NaOH)
All the above need only be installed on a temporary basis.

Residues
Slag direct to secure landfill
Fly ash direct to secure landfill
Waste water to treatment plant Advantages Low initial investment Limited civil engineering on site Pre-test before shipment Quick assembly and hook-up on site Short commissioning period on site Simple operation
