Through the configuration of steam waste heat boiler at the back end of RTO, the excess heat can be converted into high-pressure steam, which can be connected in parallel with the original steam boiler of the manufacturer or municipal steam, and then transported to the corresponding heat-using equipment by using the steam collector to regulate the temperature and pressure.
Steam heating system with standby steam heat source, exhaust waste heat to meet the workshop heat, the standby steam heat source off; exhaust waste heat does not meet the workshop heat, the standby steam heat source to make up for the heat, heat equipment start-up speed, steam flexibility, start-up time is not subject to the limitations of the RTO furnace start-up.
Steam heating system without backup steam heat source, when the waste heat of the exhaust gas does not meet the heat of the workshop, the RTO burner will make up the heat, and the start-up time of the heat equipment will be limited by the start-up time of the RTO.
Steam heating system through the pressure for long-distance transmission, so there is no need for pumps and storage tanks and other equipment, steam, water, two-phase closed-loop circulation; and steam heat exchanger through the condensing phase change for heat transfer, with a high coefficient of heat transfer, heat exchanger volume is small, the advantages of temperature control precision.
Steam waste heat utilization is suitable for ≤ 160 ℃ heat process temperature, is widely used in flexible packaging, coating, coating and food industries.
