steam boiler lifetime, what factors can affect the steam boiler lifetime

The steam boiler, as a kind of special equipment used by many enterprises is related to the people's personal safety and enterprises' property safety. What are the requirements for the steam boiler lifetime?

At present, there is no clear regulation for the steam boiler lifetime. However, steam boilers must accept the annual inspection. If the inspection result is qualified, the steam boiler can continue to be used; but if the inspection result is unqualified, the steam boiler will be ordered to be replaced. In the annual inspection of steam boilers, the boiler inspection department of Quality and Technology Supervision Bureau mainly inspects the boiler drums. As long as the drum has no bulges and the depth of pits caused by oxygen corrosion does not exceed the specified value, the boiler can continue to be used after replacing the convention tube bundles, water-cooled wall tubes, flue gas and fire tubes and other upper and lower circulation tubes, and rebuilding the furnace wall and arch.

Generally, the steam boiler lifetime is more than 20 years. Due to the differences of boiler brands, boiler materials, boiler types, boiler use and maintenance conditions, the steam boiler lifetime will vary as well.

1) Boiler brand

The boiler brand is very important because the good brand is the guarantee of quality. As an enterprise focusing on boiler manufacturing for more than 30 years, ZOZEN Boiler has established the comprehensive quality assurance system by focusing on the product research and development. The boiler structure is reasonable and the boiler raw materials can trace the source. ZOZEN also has the advanced manufacturing technology with a CNC rate of 80%, which can effectively reduce the stress of boiler assembly and welding to improve the steam boiler quality. Therefore, ZOZEN steam boiler lifetime can reach more than 30 years.

In addition, boiler enterprises with good brand reputation have stronger power and more comprehensive after-sales service system to effectively help users solve the problems in the boiler operation in time and improve the steam boiler lifetime.

2) Boiler technology

The research and development technology is the core of differentiated development in the manufacturing industry and is also a strong support of the company's product quality.

3) Daily boiler operation

In addition to the quality problems of the equipment itself, the steam boiler lifetime is mainly related to the daily boiler operation and maintenance. The boiler operator should strictly follow the standard operating procedure of the steam boiler. Before the ignition, the boiler operator should conduct a comprehensive inspection on the boiler proper, safety accessories, water supply equipment, forced draft fan and so on. The boiler operator should also be familiar with the necessary treatment measures of boiler emergencies such as emergency shutdown to ensure the steam supply for the production of enterprise.

4) Regular boiler maintenance

Monthly, quarterly and annual maintenance plans should be formulated to conduct regular inspection and measurement on the equipment and instruments of the boiler system. For instance, checking the ash accumulation condition of boiler convention tube bundles, cleaning the scale and sludge inside the drums, water-cooled tubes and headers, checking the corrosion condition of pressure-bearing welding seams and steal plates. All of these can extend the steam boiler lifetime to a great extent.

In addition, the boiler maintenance in the shutdown period is also very important which should be fully mastered by the boiler operator as well.
