Thermal Incinerator (TI)

Thermal Incinerator (TI) belongs to the classic technology for the purification of volatile organic compounds (VOC). During the treatment process in TI polluted by VOC exhaust air is transferred into tube bundle heat exchanger in a cross current flow by centrifugal fan. Onward the pre-heated exhaust air flows into the combustion chamber where VOC are burned to carbon dioxide and water.

Special equipment installed in the combustion chamber guarantees the homogene heating up of air flow and adjusts the corresponding retention time in the chamber depending on the parameters of exhaust air (VOC concentration, flow rate etc.).
