LQ-RTO Heat-storage high-temperature incineration equipment

Applicable Industries And Range

Working Principle

The tower-type RTO heats the organic waste gas to above 760 degrees Celsius, causing the VOC in the waste gas to be oxidized and decomposed into carbon dioxide and water. The high-temperature gas produced by oxidation flows through specially designed ceramic heat storage bodies, causing the ceramic bodies to heat up and "store heat," which is used to preheat the subsequent incoming organic waste gas. This saves fuel consumption for waste gas heating. The ceramic heat storage body should be divided into three or more (including three) zones or chambers, and each heat storage chamber undergoes a cycle of heat storage-release-cleaning, continuously working.

Technical Features

1. Low energy consumption: When the inlet concentration is between 1500-2000mg/m3, it can be maintained naturally without fuel supply.

2. High heat recovery efficiency: Using new materials (heat storage ceramics) technology, heat recovery efficiency can reach 95%.

3. Convenient operation: it can be controlled by traditional electrical control or industrial controllers, and after parameter calibration, it can be activated or deactivated with a single button, realizing unmanned supervision.

Process Flow

Regenerative Thermal Oxidizer (RTO) is an organic waste gas treatment equipment that combines high-temperature oxidation with multi-tower thermal storage technology. It effectively reduces heat loss and saves energy.

Equipment Selection

Regenerative Thermal Oxidizer (RTO) is an organic waste gas treatment equipment that combines high-temperature oxidation with multi-tower thermal storage technology, it effectively reduces heat loss and saves energy.

Note: The parameters in the table are for reference only. If there are specific requirements, they can be designed based on actual conditions.

Selection Criteria

1. If the exhaust gas contains corrosive components such as sulfur and chlorine, it is necessary to inform the manufacturer during the selection process. Corrosion-resistant materials such as SUS2205 or higher need to be used for processing and manufacturing, and special treatment is required for such gases in the later stage.

2. The concentration of the mixed waste gas entering the energy storage high-temperature incineration equipment shall be within the range of less than 1/4 LEL lower explosion limit.

3. The maximum temperature used by the energy storage high-temperature incineration device is lower than 960℃. High-energy substances and high-concentration gases need to be diluted. If special requirements exist, they should be indicated to make specific requirements when designing thermal insulation.

4. It is imperative that gases entering regenerative high-temperature incineration equipment are free from dust particles and oil mists that could cause blockages or flashbacks. This precaution is essential to prevent both flashbacks and the obstruction of the heat storage ceramics.

5. In certain regions, there are specific requirements for nitrogen oxide emissions from high-temperature incineration equipment. It is crucial to communicate these requirements to ensure the selection of a low nitrogen combustion system when purchasing burners. Furthermore, if the exhaust contains a high concentration of nitrogen, even a low nitrogen combustion system may not meet the emission standards, necessitating subsequent nitrogen removal processes.
