Rotary regenerative thermal oxidizer
1. Low fuel consuption，high removal efficiency, small occupied area.
2. Sutable for treatment of VOCs with low concentration and high volume.
1. Working principle
Use one rotary valve to replace switch valves (inlet, outlet and backflush) of 3-bed RTO, thus RRTO works with much higher removal efficiency, lower energy consumption and higher safety than 3-bed RTO. When RRTO working the first group of regenerative chambers filled with ceramic that have absorbed heat, is used to preheat VOCs so that the temperature of VOCs could be reach to 650~750°C while which come into combustion chamber, so the VOCs can be easily heated to 750~850°C with little or without auxiliary fuel. After combustion the hot exhaust goes into 2nd group of regenerative chambers and transmits heat to ceramic, and the temperature of ceramic goes up while exhaust`s temperature cooled down and then directly emission into the atmosphere. During above process, the one regenerative chamber is purified, the VOCs remaining in the ceramics are blown into the combustion chamber by fresh air for future combustion or sucked to the inlet of the supply fan to be resend into RTO system for disposing again.
2. Application
(1) RTO is suitable for low concentration and high volume of VOCs.
(2) RTO can deal with the VOCs contained halogen, sulfur etc. If so, the corrosion resistance material need to be considered and the flue gas need to be washed before emission.
(3) If the VOCs concentration is high, partial heat recovery shall be considered after the VOCs are oxidized, heat recovery method: Steam, hot water, hot conduction oil and hot air etc.
(4) The following information is required for consultation: volume, temperature, pressure, composition, corresponding concentration of each component.

Depending on the Volume, composition, and concentration of the VOCs,if the volume is small (normally less than 10000Nm3/h) and concentration is high(Calorific value is more than 1000Kcal/Nm3), then the first choice is thermal oxidizer(TO). If the volume is large(more than 5000m3/h) and concentration is small (normally less than 5000mg/m3),then regenerative thermal oxidizer will be considered. If t...more
