regenerative thermal oxidizer

Noun

 * 1) A type of thermal oxidizer for treating air pollutants of all types, especially VOCs and odours, by burning the gases in an oven at about 800ºC for about 1 second, while recuperating nearly all of the heat generated from the combustion of said pollutants to pre-heat the entering polluted air using a ceramic heat exchanger, thus greatly reducing energy costs. Often called an RTO.
