  • The bottom of the rotary valve RTO furnace body is 2 meters above the ground. An oil drainage structure is designed inside the furnace body, which is more conducive to oil drainage than the bed-type RTO, so that no oil is stored in the furnace body, eliminating the safety hazard of fire caused by oil accumulation at the bottom of the bed-type RTO during back-baking.

Chimney outlet temperature95℃75℃-20℃
Gas consumption statistics68℃49.3℃-18.7℃
Measurement conclusions30m³/h20m³/h-10m³/h
  • Test conclusion: Our rotary valve RTO has a chimney temperature 18.7℃ lower than that of a three-bed RTO, saving 10m³ of natural gas per hour;
  • For every 1°C increase in chimney exhaust temperature, the gas consumption increases by at least 1m³ per hour.

 

Classic Cases in the Waterproof Coil Industry

RTO coil industry case

Hongyuan Waterproof Technology Group Co., Ltd.

Founded in 1996, it has developed into a professional waterproofing system supplier integrating scientific research and development, production, sales and construction services, a “prefabricated construction industry base” and a “leading enterprise in China’s waterproofing industry”.

RTO coil industry case 
At present, the company has 5 waterproof production bases with 62 modern waterproof material production lines, with an annual production capacity of waterproofing membranes of 290 million square meters and an annual production capacity of coatings of 290,000 tons. The SBS two-meter production line and the large-scale EPDM vulcanization production line were both born in Hongyuan. The company’s products cover waterproof fields such as railways, roads and bridges, municipal administration, civil construction, industry, and military industry, with 8 series and more than 100 varieties, covering most functional requirements.

RTO coil industry case
Hongyuan Waterproofing took the lead in using 2 sets of 3-bed RTO in 2018 and 2019. In 2021, the third-generation technology rotary valve-type RTO was selected for the environmental protection equipment upgrade and reconstruction project of 3 production lines in the east factory area and 2 production lines in the west factory area, and was used in benchmarking , the rotating RTO has significant energy-saving effect and makes equipment maintenance more convenient.RTO coil industry case

When the 50,000 m3/h air volume rotary valve type RTO handles the exhaust gas of a coiled material production line, the average air volume is 20~23 m3/h, and the 35,000 m3/h air volume three-bed RTO uses 31~34 m3/h of the same air volume when processing a coiled material production line. cubic meters/hour of natural gas.

Anhui Wuhu Production Base

When the 35000m3/h air volume rotary valve RTO treats the exhaust gas from two asphalt coil production lines and the corresponding batching kettles, the average gas consumption is 21 cubic meters/hour.
