RTOs and Regenerative Thermal Oxidizer Manufacturers

What Factors Influence Thermal Oxidizer Performance?

Thermal oxidizers, also known as thermal incinerators, are pollution control devices that use heat to convert volatile organic compounds, carbon monoxide, and other volatile hazardous air pollutants from the industrial exhaust into water and carbon dioxide. Different oxidizer designs are available depending on the application. Their performance, however, is influenced by the same set of circumstances depending on the respective regenerative thermal oxidizer manufacturer.

Outlet carbon monoxide concentration, fan current, exhaust gas flow rate, outlet carbon dioxide concentration, outlet oxygen concentration, outlet combustion temperature, and outlet volatile organic compounds concentration are all discussed here. Carbon Monoxide Concentration at the Outlet; When an oxidizer is employed primarily to regulate volatile organic compound air pollution, the concentration of carbon monoxide at the oxidizer’s outlet is a measure of the system’s combustion efficiency. If carbon monoxide is detected in the exhaust, it indicates that combustion is incomplete, implying that the system is not operating at peak efficiency.

The output concentration of carbon monoxide is a clear measure of inefficiency when an oxidizer is used to examine the carbon monoxide. Currents of the Fans; In general, the fan current matches the exhaust gas flow rate. As a result, the fan current can be used as a direct measure of the gas flow rate in some instances. If the fan current rises, it means the residence time—the amount of time it takes to accomplish full combustion—is decreasing, indicating that the combustion is incomplete. Flow Rate of Exhaust Gas; the combustion chamber temperature and residence time are used to calculate the efficiency of a thermal oxidizer.

As the flow rate increases, the residence time decreases, indicating that the oxidizer’s efficiency has decreased. The gas flow rate, on the other hand, is not a performance indicator in processes when the flow rates remain constant because the temperature is a crucial element in those processes. Outlet Concentration of Carbon Dioxide and Oxygen; when volatile organic compounds are present, the outlet concentration of carbon dioxide and oxygen is a compliance indicator rather than a performance indicator. Because it indicates changes in air rate, the concentration of both gases at the output is measured.

Thermal Oxidizer Troubleshooting

To normalize the observed volatile compound to a standard oxygen or carbon dioxide level, an excess  air rate might be utilized in the computation. Monitoring both volatile chemicals and oxygen concentrations is required for compliance, especially when emission standards require compound concentrations to be adjusted to a specific oxygen percent. VOC Concentration and Combustion Temperature at the Outlet; the amount of volatile organic compound at the thermal oxidizer’s exit is a direct indicator of its efficiency and performance created by the brilliant regenerative thermal oxidizer manufacturer.

The outlet combustion temperature is a good measure of performance. The rule of thumb is that the greater the temperature at the exit, the more efficient an oxidizer is. It is recommended that rather than relying on a single sign to establish whether an oxidizer is operating well or poorly, all relevant data be gathered and analyzed to determine the performance of emission control systems.

Oxidizers made by the best RTO manufacturers have the following capabilities:

  • Capabilities: Heat will be recovered at a rate of 95-97 percent.
  • VOC destruction rates will range between 96 and 99 percent.
  • Burners with Low NOx
  • The ability to work with compounds in a solvent mixture, resulting in catalyst destruction.
  • Multiple burners are offered, including propane, natural gas, low BTU gas, LPG, and fuel oil.
  • Most applications don’t require much, if any, fuel assistance.

Each module is supported by a stainless steel frame that is individually soldered to the inside of the combustion chamber. When the neighboring module is installed, it compresses to provide lateral support.

Ceramic fibers of great purity are used to make the insulating modules. The modules are designed by RTO manufacturers to prevent the fibers from spalling or eroding, which occurs when they expand in various directions when heated.

The Air Clear insulating system is a significant component of the RTO System because of its efficiency, durability, and low maintenance requirements.

Control of VOC Emissions

Thermal oxidization’s primary design concept by regenerative thermal oxidizer manufacturers is to create a chemical reaction between air pollution and oxygen at high temperatures. By turning VOC emissions into CO2, H2O, and heat, this reaction removes VOC emissions in the air stream. Three (3) interconnected and crucial elements affect the pace of reaction: time, temperature, and turbulence.

As a high-efficiency heat exchanger, this VOC abatement technique uses ceramic medium packed into vertical canisters. Pollutants flow through the ceramic media, are combined, and stored at high temperatures in the combustion chamber, resulting in high-temperature thermal oxidation.
