The BFP Big Shot System uses kinetic-hydrostatic technology. Below you will find a brief explanation of both systems. Depending on various factors, one of both systems will be the best choice. These systems are used to shoot the projectiles through the tubes. Goodway Benelux offers 2 propulsion devices. Depending on factors such as fouling type, tube material, and previous experiences, one of both systems will be the best match. This can be either an air powered system or kinetic hydrostatic pump, which uses 100% waterpower. The propulsion systems provide the power to actually shoot the projectiles through the tubes. ![]() Almost always, a single pass is enough to clean the tubes. Projectiles travel through the tubes within seconds, leaving a clean tube behind. These projectiles are shot through the tubes at high speed and with low pressure. Goodway Benelux has various specialty projectiles which are used to remove fouling inside the condenser tubes. In fact, it's the fastest cleaning technology available in the market at this moment. A projectile tube cleaning comes pretty close. When cleaning a surface condenser, you want to keep the downtime as low as possible, while having the best possible cleaning results. Multiplied by a continous cleaning for days or weeks will lead to an extremely high amount of water being used. These systems often use hundreds of liters of water per minute. Furthermore, if operators do not handle the equipment correctly, it can lead to injuries or worse.įinally, the amount of wastewater created during a high pressure cleaning is tremendous. If a nozzle is stuck in the tube and remains on, it can cause leaking tubes due to extended exposure to high pressure. When cleaning with high pressure in enclosed rooms (such as the condenser chambers), things can go wrong when not performed correctly. Multiplied over thousands of tubes, the cleaning can easily take days, if not weeks - depending on the amount of tubes to be cleaned.įurthermore, the potential operator hazard and risk of tube damages is present. It simply takes quite some time to mechanically feed a lance and nozzle through the long condenser tubes. The big challenge with high pressure cleaning is the downtime. In case of hard scaling, a high pressure cleaning might make more sense. Most of the time, deposits inside the tubes are soft, due to the cooling media being river-, sea-, or lake water. While this system removes all the deposits, it is often considered an overkill method. In most cases power plants choose a high pressure lancing system to clean the tubes. Also, every hour of extra downtime due to cleaning, can cost the plant serious money. Thousands of tubes have to be cleaned thoroughly and carefully, without damaging them. The cleaning of a surface condenser is not an easy job. ![]() Depending on various factors, this interval period can change. This mechanical cleaning should be done once a year, or once every 2 years. In due time, a mechanical cleaning of the condenser tubes is necessary to remove fouling and balls that have gotten stuck in some tubes. This cleaning method extends the cleaning interval time, but does not exclude it. ![]() This ''deadzone'' in the tube can lead to corrosion and oxidation. This creates a blocked tube that has no flow. Also, these balls can get stuck in the tubes over time. This means that some tubes will be cleaned more often than others, and some will be cleaned less. These cleaning balls do not choose the tubes that they go in, they are sucked into the tubes that have the highest flow. Sometimes power plant operators think that this cleaning technology solves all of their fouling problems, which it does - to a certain degree. These oversized, cleaning balls remove fouling that has attached onto the tube walls. Small balls flow through the tubes during operation of the condenser. Some power plants have a taprogge (or similar) online cleaning system installed.
