Condenser Tube Cleaning: The Problem and The Solution
The condenser is a critical part of any power plant’s steam cycle. The cleanliness of the condenser has a huge impact on the overall performance and megawatt output. During operation the water side of the condenser tubes are susceptible to various fouling mechanisms such as micro and macro biological growth, mineral scaling, various types of debris, etc. These tube fouling mechanisms impede the flow of cooling water, decrease heat transfer, and damage the tube surfaces. The ultimate result of tube fouling is lower megawatt output per fuel input and tube degradation both of which create a less profitable power plant.
The solution to this problem is to frequently clean condenser tubes to remove deposits and restore the tubes back to base metal and proper operating efficiency. Most power plants will perform a cleaning either yearly or twice a year in planned outages. Proper tube cleaning regiments have significant effects that positively impact overall system efficiency, equipment integrity, and plant profitability. Some of the direct positive effects of condenser tube cleaning are: increased condenser cleanliness factor, decreased condenser back pressure, and increased flow rates. All of these metrics have direct effects on system efficiency. Removing deposits also decreases the probability of tube failure through tube leaks. Most tube leaks are caused by under deposit corrosion and removing the deposit stops the corrosion mechanism. Overall the benefits to regularly cleaning condenser tubes are extremely significant and this maintenance activity should be monitored closely by plant engineers.

Our Condenser Tube Cleaning System:
Projectile’s method for cleaning condensers and heat exchangers is called mechanical tube cleaning. The process is so named because mechanical devices, with names like: Projectiles, Bullets, Darts, Scrapers, Pigs, and Tube Cleaners, are the main mechanism for removing the deposit on the tubes.
The tube cleaning process is very similar to pipeline pigging where large volumes of water are used to force the pig through a pipe. While moving down the tube or pipe, the deposit is being ripped from the walls metal surface of the tube. Since the system’s primary deposit removal mechanism is the tube cleaner, lower water pressures can be used.
Other methods for cleaning heat exchanger and condenser tubes us high pressure water as the mechanism to create abrasion against the tube and release deposit. This method has a whole host of disadvantages compared with the Projectile Tube Cleaning method.
Using the low pressure tube cleaning method is much safer because the high water pressure, usually above 10,000 psi, can cause serious bodily harm. High pressure water blasting is also much slower than the mechanical tube cleaning process.
Typically a crew of 3-4 individuals can clean approximately 500 tubes per hour using the Projectile Method.
Other methods for cleaning tubes include using mechanical devices such as nylon brushes attached to a rotary tube cleaning machine. This method is also much slower than the Projectile Method because it is accomplished with essentially the same motion of pushing and pulling a lance down a tube.
Overall the benefits of the Projectile Method for cleaning condensers and heat exchangers is clear and this has led to it becoming the leading method for cleaning large tube bundles in the United States.
