Regulatory boiler maintenance is an important part of maintaining safety and performance for businesses using boilers. This procedure is not only mandatory but also ensures that the system operates stably and the life of the boiler is extended. Learn details about boiler maintenance and inspection in the article below to ensure regulatory compliance and safety for your business.
1. Why Boiler Maintenance is Necessary
Boilers are essential equipment in many industries, from power generation to food processing. Proper boiler maintenance not only ensures safety but also enhances efficiency and extends the lifespan of the equipment. Here are specific reasons why boiler maintenance is necessary:
1.1. Ensure Safety
Boilers operate under high pressure and temperature, creating potential risks such as boiler explosions, gas leaks, or fires. These incidents can cause significant damage to people and property. According to TCVN 6002:1995 on boiler safety, regular inspections and maintenance help detect and address issues promptly, preventing risks and protecting workers and infrastructure.
1.2. Increase Efficiency
Boilers can accumulate scale, soot, and other residues during operation. This reduces heat transfer efficiency, causing the boiler to consume more fuel to achieve the same performance level. Regular maintenance helps remove these impurities, optimizing the heat exchange process and reducing fuel costs. According to TCVN 7704:2007, a well-maintained boiler can save up to 10% in fuel costs.
1.3. Extend Lifespan
Corrosion, wear, and damage from continuous operation can shorten the lifespan of a boiler. Regular maintenance helps detect early signs of damage and conduct timely repairs, extending the equipment’s lifespan. According to TCVN 7704:2007, a properly maintained boiler can operate efficiently for 20-30 years.
Boiler maintenance needs to be performed according to regulations
2. Boiler Inspection and Maintenance Process
To ensure safety and operational efficiency, the boiler inspection and maintenance process must be carried out strictly and in compliance with national standards. Below is the basic process:
a) External Inspection
- Inspect the casing: Examine the condition of the external casing to detect signs of corrosion, rust, or mechanical damage.
- Inspect piping: Ensure water and steam pipes are free of leaks or damage.
- Inspect connections: Check pipe connections and fittings to ensure there are no leaks or malfunctions.
b) Internal Inspection
- Clean heat exchange surfaces: Remove dirt and soot buildup on heat exchange surfaces to ensure optimal heat transfer efficiency.
- Inspect fire tubes and flue: Ensure fire tubes and flues are free of deposits or damage.
- Inspect internal surfaces: Detect early signs of internal corrosion or damage for timely repairs.
c) Safety System Inspection
- Safety valves: Ensure safety valves function correctly and are not stuck.
- Pressure gauges: Inspect and calibrate pressure gauges to ensure accurate measurements.
- Gas venting system: Ensure the gas venting system operates efficiently and is not blocked.
d) Control System Inspection
- Control units: Inspect automatic control units to ensure stable and accurate operation.
- Sensors: Ensure temperature and pressure sensors function correctly.
- Electronic systems: Inspect and maintain electronic systems, ensuring there are no malfunctions or connection errors.
e) Testing and Adjustment
- Operational testing: Conduct tests to ensure the boiler operates according to standards.
- Adjustments: Make necessary adjustments to optimize performance and safety.

3. Boiler Maintenance and Inspection Cycle
According to TCVN 7704:2007, the boiler inspection and maintenance cycle is regulated as follows:
Periodic Inspection: Boilers need to undergo annual inspections to assess their overall condition. This includes both external and internal inspections, ensuring all components function correctly and show no signs of damage.
Periodic Maintenance: Every 2-3 years, boilers require periodic maintenance. This process includes detailed cleaning and inspection of crucial components, detecting and repairing damage promptly. Particularly important are components such as fire tubes, flues, and control systems.
Special Inspection: In cases of boiler incidents or prolonged inactivity, a special inspection is required before returning to operation. This ensures the safety and operational efficiency of the boiler.
4. Regulations on Boiler Inspection After Installation and Operation
According to TCVN 7704:2007, after installation and operation, boilers must comply with the following inspection regulations:
Initial Inspection: Before being put into use, boilers must undergo an initial inspection by an authorized agency. This inspection includes a comprehensive review of the system, ensuring all components function correctly and safely.
Periodic Inspection: After being put into use, boilers must undergo periodic inspections as per the regulated cycle. Periodic inspections help detect issues early and carry out timely maintenance.
Post-Incident Inspection: In case of incidents, boilers must undergo thorough inspections before returning to operation. This ensures the safety and operational efficiency of the boiler.
