AI Technical Summary

Technical Problem

During the shutdown maintenance of waste-to-energy projects or when waste transportation is not in operation, manually filling nitrogen cylinders poses safety hazards and cannot guarantee against metal corrosion of boiler heating surfaces and steam-water systems.

Method used

An automatic nitrogen system was designed, including a nitrogen preparation unit, a nitrogen drying unit, a nitrogen control unit, and a signal acquisition unit. The system realizes the automatic preparation, drying, and control of nitrogen. The signal acquisition unit monitors and automatically adjusts the equipment operation in real time to ensure that the nitrogen quality and pressure meet the requirements.

Benefits of technology

It achieves fully automated nitrogen supply, reduces the risk of manual operation, avoids nitrogen leakage and explosion, ensures that nitrogen quality meets standards, protects boiler equipment from corrosion, and reduces labor costs and safety hazards.
