What Are the Intended Functions of an RTO As Designed By Regenerative Thermal Oxidizer Manufacturer?
Thermal oxidizers are a large piece of equipment that is most commonly employed in industrial situations where substantial emissions are produced. To ensure optimal oxidation, it’s critical to think about the needs of a certain application before making a purchase. Because thermal oxidizers work by burning or heating pollutants, temperatures are critical, ranging from 1000 to 1800 degrees Fahrenheit on average. The solvent load and volume, as well as the requisite airflow, must all be considered. The destruction effectiveness of a correctly chosen thermal oxidizer should be between 90% and 99 percent, as the regenerative thermal oxidizer manufacturers designed it. The lower this proportion is, the fewer contaminants are released into the air.
The EPA encourages and frequently requires the use of air pollution control techniques such as thermal oxidizers, which are a popular choice in industrial settings with significant process air emissions, as worries about emissions grow.
Direct flame and non-flame thermal oxidizers are the two types of thermal oxidizers. The former is the most straightforward method, as it only necessitates a firing box into which the process stream flows. The ingredients are converted as needed by a burner. The amount of time required to achieve this goal varies. Non-flame oxidizers are more common since they allow for more heat energy to be recovered and reused.
The polluted air is pumped through a heated tube that gradually raises the temperature until the pollutants are broken down in these systems. After that, the cleansed air is released into the atmosphere. In this form of pollution control equipment, heat recovery systems can be either recuperative or regenerative. Using a plate or shell and tube heat exchanger that uses the heat from recently cleansed air to heat the unclean entering air, recuperative models recover roughly 50 percent to 75 percent of the generated heat. Because the regenerative thermal oxidizer manufacturers designed the RTOs to use ceramic heat transfer beds, regenerative models are substantially more efficient, with up to 95 percent energy efficiency.
The regeneration principle is based on the utilization of multiple energy recovery chambers, which are the housings for the ceramic heat recovery medium in the system. The system’s ceramic heat recovery media serves as a heat exchanger. The numerous chambers work on the “swing bed” absorption principle, which is the principle of flow reversal to transfer via several beds. The method of using this idea with ceramic stoneware is known as regeneration. The exhaust stream absorbs the thermal energy stored in the ceramic media mass as it passes through the first bed of ceramic media, which pre-heats the exhaust stream.
The exhaust stream next passes through the burner reactor chamber, where heat energy from the burner is injected to bring the system temperature up to operational temperature. The clean exhaust stream subsequently travels through the second energy recovery chamber after the temperature has been raised.
As the exhaust stream passes through the chamber, the cold ceramic media mass absorbs the exhaust stream’s heat energy and stores it for the system’s reverse flow.
To maintain the system’s minimum operating temperature, reversing exhaust flow through the ceramic beds requires only a small quantity of heat energy to be added to the incoming exhaust stream. The ceramic media beds are sized so that the regenerating, reverse flow process can achieve a heat recovery efficiency of 95% or more.
It’s fascinating to see what happens when you use a Regenerative Thermal Oxidizer and how much the regenerative thermal oxidizer manufacturer thought about it. Through an intake manifold, gas packed with volatile and dangerous pollutants enters a twin Bed RTO. As the gas stream travels into the combustion chamber, the heat exchange media bed (also known as the stoneware bed) continues to heat the process gas and pollutants.
Traditional Regenerative Thermal Oxidizer (RTO) components include system fans, motors, burners, heat exchange media, flow control valves, electronic and automated system controls, temperature recorders, and exhaust stacks. The skin of the system is usually lined with ceramic but is mainly composed of steel.
What Are Advantages And Disadvantages Of RTOs?
Advantages:
- Capital cost is moderate.
- Low operating expenses and low pollution concentrations in the air thanks to the workings of RTO manufacturers
- Thermal heat recovery is extremely high.
- High inlet temperatures are possible.
Disadvantages:
- The simple two-chamber design can only remove 98 percent of VOCs.
- Greater moving parts necessitate more upkeep.
