Hazardous Waste
Thermal utilisation of hazardous waste plays a critical role in the chemical industry.
Example:
Hazardous waste incineration plant Lonza AG in Visp / Switzerland
Features
Long residence time of flue gases in the radiation part with cooling down to 450 °C
Low flue-gas velocities for lowest possible erosion
Operation in natural circulation
Highly efficient vaporiser heating surfaces in the radiation section
Complete accessibility of the wall heating surfaces from outside
Masonry-free and flue-gas-tight overpressure design
Cleaning of the convective heating surfaces in operation by mechanical vibration
Minimum number of ash-removal points
Advantages
Operation determined exclusively by the waste programme
High-temperature-corrosion free boiler operation
Complete utilisation of the exhaust heat in the scope of the existing cogeneration
