The fully premixed condensing steam generator is a special equipment. To ensure its normal operation, prevent accidents, and maintain the boiler's normal service life, daily boiler operations must strictly adhere to the following requirements:

1. Certified Boiler Operators: Boiler operators must obtain a boiler operator certificate issued by the Municipal Bureau of Quality and Technical Supervision before operating the boiler (this requirement was emphasized by the Bureau of Quality and Technical Supervision personnel during the boiler acceptance inspection).

2. Strengthen Water Quality Management: In fully premixed condensing steam generators, continuous evaporation of boiler water leads to increasing concentration and scaling. Moreover, excessively high boiler water concentration can cause boiling phenomena, resulting in false water level indications, affecting normal operation, and in severe cases, leading to dry firing and furnace tube bulging accidents. To prevent such occurrences:

A. Enhance Management of Boiler Water Treatment Equipment: Regularly test the effluent from the boiler water treatment system to ensure that the boiler feed water meets the standards specified in GB1576 "Water Quality for Industrial Boilers."

B. Strengthen Management of Boiler Water in Fully Premixed Condensing Steam Generators: Periodically test the water quality inside the boiler to ensure it complies with the standards of GB1576 "Water Quality for Industrial Boilers." Perform reasonable blowdown to promptly remove water slag.

Daily Use and Operation of Water Level Gauges: Water level gauges should be kept clean at all times to avoid contamination that could obstruct water level observation and cause scale buildup in connecting pipes, leading to false water level indications and potential boiler accidents.
