As a common intelligent industrial thermal energy equipment, gas boilers have many parts. Timely and correct replacement of damaged parts is of great help to ensure the efficient and safe operation of the boiler. So when should the gas boiler parts be replaced? What are the main points of boiler maintenance?

Gas Boiler Parts Replacement

　　Due to the many components involved in the boiler, here is an introduction to the replacement standard of the heating surface of the gas boiler:

　　1. Pipe replacement. If the heating gas boiler uses carbon steel pipe, it should be replaced in time if the expansion exceeds 3.5%. If the expansion exceeds 2.5%, it should be replaced.

　　2. Superheaters and boiler superheaters should be replaced in time if the surface oxide scale has exceeded 0.6-0.7mm and there are oxidation cracks.

　　3. For the economizer tube, if the wear amount has reached 30% of the wall thickness, it is necessary to replace it.

The importance of boiler maintenance

　　The timely maintenance and replacement of boiler components can not only ensure the safe operation of the boiler, reduce the failure rate and reduce the cost of shutdown and maintenance, but also play an irreplaceable role in the thermal efficiency of the boiler, that is, high-efficiency operation. It is necessary to be familiar with the names and functions of the components, and at the same time, master the standards and elements of replacement, and preferably record the work, so as to manage the gas boiler in a more standardized manner.
