Regenerative thermal oxidizer process flow diagram.

A regenerative thermal oxidizer rto is a piece of industrial equipment used for the treatment of exhaust air the system is a type of thermal oxidizer that uses a bed of ceramic material to absorb heat from the exhaust gas it then uses this captured heat to preheat the incoming process gas stream and destroy air pollutants emitted from process exhaust streams at temperatures ranging from 815. Inlet switch valves direct the pollutant laden air into one of the energy recovery canisters.

The simplest technology of thermal oxidation is direct fired thermal oxidizer.

Historically the most commonly used is the regenerative thermal oxidizer rto although recuperative thermal oxidizers are becoming more common icac 2016. Industrial manufacturing and other processes often produce volatile organic compounds vocs that must be abated. Regenerative thermal oxidizers destroy volatile organic compounds vocs and hazardous air pollutants haps that are created through chemical processes and industrial exhaust steams this type of oxidizer uses extremely high heat about 1500 f to clean the exhaust of dangerous pollutants and compounds. An rto burns very lean waste gases without using much fuel.

Regenerative thermal oxizizer pc to 102 figure c 4c. The process begins with a high pressure supply fan that forces exhaust fumes into the regenerative thermal oxidizer. Operating temperature is about the same as a normal thermal oxidizer say 1600of but the hot flue gas passes through a heat exchange module before reaching the stack. Table 2 1 provides capital cost estimates for thermal oxidizers in several industry source categories.

A process stream with hazardous gases is introduced into a firing box through or near the burner and enough residence time is provided to get the desired destruction removal efficiency dre of the vocs. One of the most efficient technologies to a. 1 incinerators should not be confused with flares.
