Wuxi Zechuan Environment, a professional manufacturer of RTO incinerators, RTO, RCO, and VCU equipment, July 19, 2025, excerpted from the VOCs reduction workstation. The RTO system is the largest branch of the VOCs treatment industry, without any doubt. Although RTO incineration is one of the most direct and efficient treatment methods, many environmental protection manufacturing enterprises or users believe that burning RTO can solve all their problems. Little do they know that there are still many pitfalls to fall into. Today, we are going to share a few of the most common misunderstandings, just for communication.
1. Only focusing on the initial investment while neglecting the stability of operation and compliance
Misconception: "RTO is too expensive. If possible, make it cheaper. Just replace the activated carbon equipment."
Correct answer: RTO is a one-time investment with multiple years of returns. For scenarios with medium to high concentrations, large air volumes, and continuous operation of waste gas, the long-term operating cost of activated carbon is much higher than that of RTO, and the compliance is unstable. In addition, if the concentration of the incoming gas is relatively high, it is advisable to consider combining a waste heat boiler for the utilization of waste heat.
2. Do you think RTO is a "universal machine" that can handle all kinds of waste gas
Misconception: "Just apply RTO to organic waste gas without considering concentration, impurities, or moisture."
Correct answer: RTO is highly sensitive to the concentration of exhaust gas, temperature, water content, and halogenated hydrocarbons such as silicon and chlorine. If not pre-treated, it may corrode the system, clog the heat storage bed and cause malfunctions.
Pretreatment equipment (dust removal, acid removal, condensation, activated carbon/resin adsorption and desorption, etc.) must be selected based on the gas quality components.
For certain components of waste gas (such as halogenated hydrocarbons and chlorinated solvents), it is more recommended TO use TO or other processes such as deep cryogenic treatment, activated carbon/resin adsorption and desorption shallow cryogenic treatment as substitutes.
3. Neglecting the significance of "switching valves" and "automatic control systems"
Misconception: "As long as the burner is pushed into the furnace and can heat up to over 760℃, it can burn off organic matter."
correct solution: The switching valve is one of the key factors determining whether the emissions can meet the standards. As a moving device with a very high operating frequency, the switching valve is relatively more prone to failure. It is absolutely not advisable to install some switching valves that are merely roughly made of iron, with two steel plates and a private label for execution. In such cases, it will be difficult to directly identify the cause even if the standards are exceeded, especially in industries like pharmaceuticals and chemicals where the concentration of incoming gas is relatively high. The leakage of the switching valve will directly lead to the occurrence of over-standard. Furthermore, the automatic control system determines whether it operates stably. It is not the case that once the RTO burns out, everything will be settled. When the switching valve system lacks precise reversing and temperature control strategies, the system will exhibit:
VOCs emissions exceed the standard;
Frequent ignition and high gas consumption;
The lifespan of the equipment has been shortened.
