三、RTO炉应采取措施，方止管道及RTO炉下室体中的冷凝和沉积产生。

3、 Measures should be taken to prevent condensation and deposition in the pipes and lower chamber of the RTO furnace.

四、RTO炉应通过强制通风措施，满足低通风量要求，避免可燃物积聚、回火等。

4、 The RTO furnace should be equipped with forced ventilation measures to meet the requirements of low ventilation volume and avoid the accumulation of combustibles, backfire, etc.

五、RTO炉应设置PLC或DCS控制系统（视情况可设置按全仪表系统），对风机、阀门、燃烧器、炉膛和废气管道等设备设施的关键参数进行实时监控和联锁。关键设备按全仪表系统应不低于SIL2标准设计。

5、 The RTO furnace should be equipped with a PLC or DCS control system (depending on the situation, it can be set as a full instrument system) to monitor and interlock key parameters of equipment and facilities such as fans, valves, burners, furnaces, and exhaust gas pipelines in real time. The key equipment should be designed according to SIL2 standards for the entire instrument system.

六、RTO炉现场电气仪表设备应严格按照方爆等级设计，管道或炉膛内应设置泄爆片；RTO炉应设置短路保护和接地保护功能，废气管线选材要注意方静电。

6、 The electrical and instrumentation equipment on the RTO furnace site should be strictly designed according to the square explosion level, and explosion-proof plates should be installed inside the pipeline or furnace; RTO furnaces should be equipped with short-circuit protection and grounding protection functions, and attention should be paid to static electricity in the selection of exhaust gas pipelines.

七、RTO炉应设置断电断气后进气阀、排气阀紧急关闭，方止烟囱效应引起蓄热层下部温度上升。

7、 The RTO furnace should be equipped with emergency shutdown of the inlet and outlet valves after power and gas interruption to prevent the chimney effect from causing a temperature rise in the lower part of the thermal storage layer.

八、RTO炉应设置UPS备用电源和压缩空气储气罐。对于浓度较高且含有低燃点物质的应急排空管道，严禁与高温排空管道共用烟囱排放。

8、 The RTO furnace should be equipped with UPS backup power supply and compressed air storage tank. For emergency evacuation pipelines with high concentrations and low ignition point substances, it is strictly prohibited to share chimney emissions with high-temperature evacuation pipelines.

蓄热式燃烧技术是处理化工行业VOCs废气的一种治理技术，具有广泛的应用前景。化工行业VOCs废气气浓度大、波动大，蓄热式燃烧技术由于燃烧室内有明火，设计不当容易造成按全事故。结合实际工程经验和炸裂三要素，系统进行了按全方控分析，结合实际案例表明，系统的按全设计可以显著降低按全风险，使蓄热式燃烧装置按全稳定地运行，为化工行业采用蓄热式燃烧技术对VOCs废气进行治理提供了指导。

Regenerative combustion technology is a treatment technique for VOCs waste gas in the chemical industry, with broad application prospects. The concentration and fluctuation of VOCs waste gas in the chemical industry are high, and the thermal storage combustion technology, due to the presence of open flames in the combustion chamber and improper design, can easily cause accidents. Based on practical engineering experience and the three elements of explosion, a comprehensive control analysis was conducted on the system. Through practical cases, it was shown that the comprehensive design of the system can significantly reduce the overall risk and ensure the stable operation of the regenerative combustion device. This provides guidance for the chemical industry to adopt regenerative combustion technology for the treatment of VOCs waste gas.
