Fully Premixed Condensing Steam Generator, as a special equipment, requires strict adherence to the following operational requirements to ensure normal operation, prevent accidents, and maintain the boiler's service life:

         1. Certified Boiler Operators: Operators must hold a boiler operator certificate issued by the Municipal Bureau of Quality and Technical Supervision to perform operations (this requirement has been emphasized by the Bureau during boiler acceptance inspections).

         2. Strengthen Water Quality Management: In fully premixed condensing steam generators, continuous evaporation of boiler water leads to increased concentration and scaling. Additionally, excessively high boiler water concentration can cause boiling phenomena, resulting in false water level readings. This affects normal operation and, in severe cases, may lead to dry firing and furnace drum bulging accidents. To prevent such occurrences:

         A. Enhance Management of Boiler Water Treatment Equipment: Regularly test the effluent from water treatment systems to ensure boiler feedwater complies with the GB1576 "Water Quality for Industrial Boilers" standard requirements.

         B. Strengthen Management of Boiler Water in Fully Premixed Condensing Steam Generators: Periodically test the internal water quality to ensure it meets the GB1576 standard requirements. Implement reasonable blowdown procedures to promptly remove water slag.

         Daily Use and Operation of Water Level Gauges: Water level gauges should be kept clean regularly to avoid contamination that may obstruct water level observation. Accumulation of scale in connecting pipes can cause false water level readings, potentially leading to boiler accidents.
