Taprogge
Taprogge GmbH is a medium-sized company based in Wetter, Germany. The company is named after founding brothers Ludwig and Josef Taprogge. Founded in 1953, the company is known for its tube cleaning systems for steam turbine condensers, heat exchangers and debris filters for water-cooled shell and tube heat exchangers and condensers.
== Invention of the tube cleaning system ==
''Josef Taprogge'' was a turbine engineer in a power plant nearby Essen and was responsible for the cleaning of the turbine condenser tubes. Cleaning had to be performed while the turbine was out of operation, with the power station not being able to supply any electrical energy to the grid during the turbine outage. On the other hand, the careful elimination of fouling from inside of the tubing is important for a high vacuum in the condenser and thereby for the optimal efficiency of the energy generation through water vapour.
To avoid economic losses caused by shutdowns, Josef Taprogge invented a continuously working cleaning system which kept the condenser free from fouling during the operation of the steam turbine. A prototype was installed into the cooling water pipe leading to the condenser. During the time of the German Wirtschaftswunder, the process which was marketed and further developed by Taprogge GmbH was widespread and very well received in the power stations due to its efficiency. The efficiency of the power stations that are equipped with the systems increases by around 2 – 4%. The cleaning process became well known and the name "Taprogge System" has been used in the technical literature.
