Fully premixed condensing steam generators are special equipment. To ensure their 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, the continuous evaporation of boiler water leads to an increase in concentration and scaling. Additionally, 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 drum bulging accidents. To prevent such occurrences:

A. Strengthen the management of boiler water treatment equipment: Regularly test the effluent from the water treatment system to ensure that the boiler feedwater meets the requirements of the GB1576 "Water Quality for Industrial Boilers" standard.

B. Strengthen the management of boiler water in fully premixed condensing steam generators: Periodically test the water quality inside the boiler to ensure it complies with the GB1576 "Water Quality for Industrial Boilers" standard, and perform reasonable blowdown to promptly remove sediment.

Daily use and operation of the water level gauge: The water level gauge should be kept clean at all times to avoid contamination that may obstruct water level observation or cause scale buildup in the water connecting pipes, leading to false water level indications and potential boiler accidents.
