How to clean the boiler

The boiler adopts light furnace wall and pipe-laying furnace wall structure, which can be freely expanded in all directions, with light weight and good heat preservation performance. The boiler is easy to arrange and suitable for various capacities and various fuels. The auxiliary heating surfaces such as energy saver and air preheater are supplied in a modular way to reduce the installation workload on site. Membrane wall and serpentine tube adopt standardized design to reduce the delivery cycle.

1、 Cleaning method

Machine wash

Mechanical cleaning is a manual cleaning using a high-pressure water gun. Generally speaking, scale, blockage or surface deposit will be removed inside the boiler, regardless of scale deposit such as rust Iron oxide scale, resin, chemical residue, paint, epoxy resin, etc. can be completely removed by cleaning with a high-pressure water jet cleaner.

Chemical cleaning

Chemical cleaning is acid cleaning. Only certified manufacturers and environmental protection units with certification certificates can clean. The rust, scale and oil stain in the boiler system are cleaned and dispersed by adding chemical cleaning agent to restore the clean metal surface.

2、 Cleaning procedure

Understand the situation

Understand the structure, materials and heat transfer mode of boiler cleaning. There are dozens of boilers on the market, each with different heat exchange methods, structures and materials, and each structure and material requires different cleaning methods. Cleaning personnel analyze and test different areas, water quality and scales, prepare different chemical cleaning agents for different materials and scales, and propose scientific and reasonable cleaning schemes.

Descaling and cleaning

According to the proportion of boiler cleaning and descaling, add a set of descaling cleaning agent to the circulating water of the cleaning tank to determine the cleaning cycle time and the amount of agent added. Scale.

Clean with clean water

After cleaning the equipment and connecting the boiler, circulate clean water for 10 minutes, check the system status and whether there is leakage, and remove the floating rust at the same time.

Stripping anti-corrosion cleaning

Add an appropriate amount of surface remover and slow-release agent into the circulating water in the cleaning tank, and conduct a circulation cleaning for 20 minutes to separate the scale from the parts to be cleaned. Remove the scale during cleaning, so that the cleaning agent will not corrode the parts to be cleaned. The surface is subject to anti-corrosion treatment.

Passivation coating treatment

Add passivation coating agent to passivate the boiler cleaning system to prevent corrosion of pipes and components and formation of new rust.
