In process industries such as petroleum, chemical, coking, coalification, and pharmaceuticals, VOCs waste gas treatment is a necessary link for green production, and thermal storage incinerators (RTOs) have become the mainstream choice due to their efficient treatment capacity. However, the composition of exhaust gas is complex and varied, with combustible gases mixed in like hidden flash explosion hazards. Once the concentration accumulates and exceeds the lower explosive limit (LEL), entering the RTO high-temperature furnace, it is highly likely to cause catastrophic flash explosion accidents, seriously threatening personnel safety, equipment integrity, and production stability.

In the face of common risks in this industry, post remediation is far from enough, prevention is key. Deploying flame temperature detection (FTA) principle based on the intake front end of RTO systemLEL concentration monitorIt is the core technological means to cut off the risk chain from the source and achieve intrinsic safety.

FTA detection technology achieves direct and rapid response to LEL concentration by accurately measuring the temperature changes caused by the combustion of combustible gases under specific conditions. Its outstanding advantages lie in:

-Rapid response, seize the opportunity: With a response time of less than 1 second, it can instantly capture abnormal spikes in exhaust gas concentration, which is several times faster than traditional detection methods, winning valuable emergency intervention windows for the system.

-Accurate and stable, strong anti-interference: not easily affected by background gas, humidity, dust and other factors in exhaust gas, ensuring continuous output of reliable data in complex and changing industrial exhaust gas environments.

-Real time online, continuous protection: 24-hour uninterrupted monitoring, dynamic tracking of concentration trends, upgrading safety monitoring from intermittent spot checks to full coverage.
