Regenerative Thermal Oxidizer Efficiency

Regenerative Thermal Oxidizer Cost Versus Design

You planned a purchase, found some RTO and now you are wondering what is the Regenerative Thermal Oxidizer Efficiency of each of those so you can choose the best. Let us  first explain what are they and how they work. A regenerative thermal oxidizer is a gas cleaning device that removes pollutants from flue gases. These are usually used to comply with air quality regulations for emissions of hazardous materials, such as sulfur dioxide and nitrous oxides.

Unlike other air pollution control devices, which consume significant amounts of energy by running continuously, the regenerative thermal oxidizer can be switched on or off depending on whether it is needed. This makes it more efficient than other methods of removing contaminants from flue gases.

The regenerative thermal oxidizer efficiency level will depend mainly on the design chosen for the system. Suppose you want to increase your regenerative thermal oxidizer’s efficiency. In that case, there are many factors you should consider when designing your unit, including cost versus design, size versus design, equipment functions, and location.

How does the design of an RTO impact its efficiency? 

The regenerative thermal oxidizer design will impact its efficiency. Many variables go into the creation of an RTO. Some are dependent on the equipment available, some are dependent on site conditions, and some are based on personal preference.

– Basic regenerative thermal oxidizer Design Considerations –

A basic regenerative thermal oxidizer consists of several components, including a conduit to transport flue gases and air preheater to prevent the loss of heat that would otherwise be used to generate steam, a regenerator where chemical reactions take place between nitrogen oxides and ammonia occurs, and a venturi scrubber.

– Regenerators –

The regenerator is designed with a fluidized thermal bed of limestone aggregate. The regenerative thermal oxidizer design affects the level of efficiency that will be achieved. Some plans are better for achieving higher efficiencies than others, but they require more complex equipment and higher maintenance costs to run effectively.

– Maintenance –

The price of a regenerative thermal oxidizer is dependent on the complexity of the regeneration process, which is determined by the type of regenerator and its size. A more complex regenerative thermal oxidizer will cost more to maintain over time.

The cost of running an RTO compared to other pollution control measures?

There are many ways to reduce the number of nitrogen oxides in flue gases. Regenerative thermal oxidizer cost versus design should be considered when determining whether it is the best option for your facility.

Other options include fabric filters and wet scrubbers, which can achieve a high level of pollutant removal from flue gases. These systems effectively remove contaminants from gas streams, but they consume a significant amount of energy that will add to your facility’s operating costs.

Factors that will affect the regenerative thermal oxidizer cost?

 

– Size –

A regenerative thermal oxidizer will cost more to install than other systems because of the higher investment costs, such as increased labour and material requirements. The regenerative thermal oxidizer that you choose should be sized correctly so it can meet your facility’s operational needs and do so economically.

– Preference –

Another factor affecting the regenerative thermal oxidizer cost is personal preference. Some regenerative thermal oxidizers require a limestone bed, while others can instead use an orasorb zeolite bed. The difference in regenerative thermal oxidizer efficiency when using these beds depends on the flue gas composition and temperature.

– Location –

The location of your facility also impacts the regenerative thermal oxidizer cost. The regenerative thermal oxidizer can be purchased in many sizes, but the more significant the unit is, the more costly it will be to buy and install.

– Maintenance –

The type of design chosen for your regenerative thermal oxidizer will impact maintenance costs, making some regenerative thermal oxidizer designs more expensive than others over time. The physical location of the regenerative thermal oxidizer will also impact maintenance costs because it will be harder to access equipment in some areas than in others.

– Product Recovery –

If your facility uses a regenerative thermal oxidizer for air pollution control, you may need to recover the excess heat that exits your system.

Design considerations for optimizing RTO performance. 

– Heat Losses –

Heat is released during the combustion process that can be captured and recycled by regenerative thermal oxidizers. However, some of this heat will escape into the atmosphere or surrounding equipment during the regeneration process.

– Temperature –

The amount of energy lost due to temperature fluctuations depends on the specific regenerative thermal oxidizer design of the regenerative thermal oxidizer. A unit that has higher temperature swings will lose more energy during regeneration.

– Temperature Limits –

Temperature limits can be set on regenerative thermal oxidizers to prevent damage due to excessive heat exposure. This can also decrease RTO efficiency because it requires additional time for gas cooling.

A regenerative thermal oxidizer is a device that can be used to create some of the cleanest air possible, but it does come with a hefty price tag. If you’re able to invest in one for your facility or company, then it’s worth doing so because they have been proven to reduce energy consumption and operating costs by as much as 85%. However, if this isn’t an option for you at this time, there are still ways to go about reducing emissions from power plants and other sources without investing too heavily into such equipment.
