WHAT IS
•Incinerator : a furnace to burn waste.
•A thermal oxidizer: a process unit for air pollution control in manychemical plants that decomposes hazardous gases/liquid at a high
temperature and releases them into the atmosphere.• In the Incinerator the chemical/Biological waste is burnt at itsdestruction temperatures. The outlet streams are monitored for thesafety of the Environment before releasing to atmosphere.
