Treating hazardous waste is about the safe incineration (destruction) of the dangerous material contained in the hazardous waste. Moreover, issues such as the circular economy and energy recovery are also increasingly important. To incinerate hazardous waste, a higher temperature of 1,100 °C must be ensured compared to the 850 °C which must be maintained for municipal waste treatment. With a few exceptions, the rotary kiln with a secondary combustion chamber is used as a combustion system. It has proven itself in practice with more than fifty years of operational experience. Installations for hazardous waste are a special segment in the thermal treatment of waste. Each plant has its requirements and requires individual planning. Kanadevia Inova is your professional partner – from the concept phase to engineering, construction to commissioning and maintenance throughout the plant’s entire life cycle.

Due to the required high-temperature incineration, hazardous waste treatment plants mainly operate with rotary kilns as combustion systems. These rotary kilns have a length of up to 15 meters, an outer diameter of as much as 5.5 meters and are specially designed for high temperatures with their fire-resistant coating. The secondary combustion chamber (SCC), which is sub-connected to the rotary kiln, takes on the task of completely burning out the exhaust gases of the rotary kiln (residual organic substances, crushed solid particles, CO strands) and ensuring the legally required two-second residence time at 1.100 °C. Solid wastes are placed in the front of the rotary tube, and liquid and gas waste can be inserted into the rotary kiln or at the beginning of the secondary combustion chamber. In all cases, complete burnout is ensured. We support you, no matter if it is maintenance, modification, or renewal of existing assets.
