Shandong Jining Greentech specializes in cleaning boiler preheaters for 12 years, boasting rich industry experience and reasonable prices. Welcome both new and old customers to visit.
To enhance the efficiency of boiler operation, the high-temperature flue gas after air preheating is recycled, which, when used to preheat the air, aids in combustion and helps raise the incoming air temperature of the boiler equipment. Not only does this recover flue gas heat, but it also boosts the boiler's efficiency. The air preheater can heat the flue gas from the boiler's exhaust duct after combustion to the air within the boiler, achieving a flue gas waste heat recovery rate of over 97%, significantly reducing the loss of excess heat.
Boiler air preheaters are an essential component of the boiler combustion system, serving to preheat the air entering the boiler before combustion, thereby enhancing combustion efficiency. If the air preheater is affected by dirt blockage, it can lead to incomplete combustion and reduced thermal efficiency. Therefore, regular cleaning of the air preheater is a necessary measure to maintain normal boiler operation. Jining Gelan Chemical has focused on boiler cleaning services for many years, tailoring reasonable cleaning plans and implementations to meet the specific characteristics of the client's boiler operation.
The scaling dust in air preheaters is mainly composed of salts like calcium carbonate and magnesium carbonate. Failure to clear and clean these will result in more severe clogging of the equipment after use. Standard power plant self-cleaning methods can only remove some surface dust, not thoroughly clearing the scaling. Without removing static electricity, clogging will occur in the short term. Professional cleaning companies are needed for thorough cleaning and unblocking.
During the descaling and cleaning process of the air preheater, first, use a high-pressure water jet to rinse away the floating ash, then repeatedly flush the heat exchange elements of the air preheater with the high-pressure water jet until clean. Open the air preheater's cleaning drainage system, further process the heat exchange elements after cleaning, and thus complete the descaling and cleaning of the air preheater.
