A thermal oxidizer (also known as thermal oxidiser, or thermal incinerator) is a process unit for air pollution control in many chemical plants that decomposes hazardous gases at a high temperature and releases them into the atmosphere.
Furnaces used for diffusion and thermal oxidation at LAAS technological facility in Toulouse, France. In microfabrication, thermal oxidation is a way to produce a thin layer of oxide (usually silicon dioxide) on the surface of a wafer. The technique forces an oxidizing agent to diffuse into the wafer at high temperature and react with it.
Ventilation Air Methane Thermal Oxidizers can be designed with hot gas bypass systems, re-circulation heat exchangers that convert heat into energy, and oxygen monitoring to reduce any possible carbon monoxide and/or nitrous oxide production. Methane streams allow the VAMTOX to operate at reduced or zero fuel usage, which makes these systems ...
A regenerative thermal oxidizer (RTO) is an example of a waste heat recovery unit that utilizes a regenerative process.. A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency.
Its role is to produce controlled amount of heat. Pyrotechnic heat sources are usually based on thermite-like (or sometimes delay composition-like) fuel-oxidizer compositions with slow burn rate, high production of heat at desired temperature, and low to zero production of gases. Pyrotechnic heat sources can be activated by multiple means.
Thermal oxidation can be accomplished using a catalytic oxidizer, an afterburner or by routing the offgas to the combustion heat source for the desorber. The volume of gas requiring treatment for indirect fired desorbers is a fraction of that required for a direct fired desorber.
About 200 mines across a broad scope of countries had implemented technology by the year 2015 to capture about 3 million tons of methane, either for economic use or for abatement in gas flares or thermal oxidizers. [12]
The concentrated VOC gas stream is sent from the desorb tower to a thermal oxidizer, where the organic compounds are heated to 1400 °F and oxidized, or broken down into carbon dioxide (CO 2), water (H 2 O), and by-products. In some cases, small amounts of carbon monoxide (CO), nitrogen oxide (NO X), and other gases are produced.
