The Taprogge GmbH is a medium-size enterprise in the legal form GmbH with seat in weather (Ruhr) in the local part whom gladly. At the 1. March 1953 of the buyer Ludwig Taprogge (* 18 September 1920) in Duesseldorf meadow mouth created company manufactures cleaning equipment and late filters for water-cooled bank of tubes heat exchangers and condensers for this time. The exempt private company with approximately 350 coworkers is regarded within this technological range as a market leader and possesses branches and agencies in many countries in the world.
First suitor coworker of the company was the brother of the firm founder, Josef Taprogge (* 15 November 1914, " 27 November 1961), an engineer for power plant technology in the steam power plant at that time in meal copper trick. As a plant manager it was responsible to a time-consuming and very dirty activity for the tubing cleaning of the Berohrung of the turbine condensers. This cleaning had to be made with standing turbine, whereby the power station could not deliver any electricity during this downtime in the net. On the other hand the careful removal of contamination of the inside was the Berohrung extraordinarily importantly for a high vacuum in the condenser and thus for the optimal efficiency of the energy production by water vapour. After such a cleaning however again the pipes got dirty within shortest time. For the avoidance of these economic losses Josef Taprogge invented therefore continuously working cleaning equipment, which kept free the condenser of contamination during the enterprise of the steam turbine, and inserted a prototype into the cooling water pipe to the condenser of the power station.
Of the company developed further and marketed procedure found during the time of the Wirtschaftswunders by its efficiency in the power stations far spreading. Since that time the increase of the efficiency within the power stations equipped with the plants amounts to about two to four %, so that this investment amortizes within fewer months. The Bekanntheitsgrad of the cleaning method became so large in the circles of the specialists that to today the term was in-patriated Taprogge procedures in the technical literature. The enterprise expanded therefore rapidly. 1957 could be already created a branch in the USA, 1963 followed an address in Great Britain and 1967 an address in Japan. On 15 December 1997 as past conclusion the Chinese production location in Shanghai was created.
The procedure patented invented by Josef Taprogge and plans sponge rubber balls, which are fed before the entrance into the condenser into the river of the cooling water (1). The diameter of the balls is somewhat larger than the nominal size of the Kondensatorberohrung. By their elasticity they produce a contact pressure, which cleans the pipes reliably on their way by the condenser tubes. At the withdrawal of the condenser a filter (2) is in the following piping, which holds the balls from landing on water Rome back and into a following piping of the nominal size DN 80 leads. From there out they are back-pumped by a centrifugal pump (3a) with an output of four KW and via a piping with DN 80 the output place. In order to be able to bring the balls for the first time into this cycle, a receiver with solvable cover is behind the pump. Within this, air-lock (3b) mentioned, receiver is likewise a filter and a flap. With opened flap the balls can pass, with closed flap remain them in the air-lock and can be supplemented or exchanged. The procedure works continuously, the pipes remains free by persistent contamination such as mud, algae, bacteria and boiler scale. The enterprise of the plant is supervised over sediment bowls and electronic measuring instruments. The surfaces of the filters are swivelling stored on waves and can be swivelled if necessary, in order to eliminate contamination from landing on water Rome to. The balls become imprisoned with this procedure in the air-lock. This time-consuming procedure is automated (3c), gear motors (m) operates the necessary drives. The nominal size of the filters could hold 150 to DN 4900 with the growth thrusts of the power plant technology to today step and extends from DN. The diameter of the balls moves between 14 and 30 mm with typically unites one hundred until far on thousand balls per air-lock filling. The life span of the balls made of biologically degradable natural rubber can amount to up to four weeks.
As a special procedure cleaning equipment for the seawater desalination is manufactured. Since with "Brine" marked sea waters heated up particularly corrosively works, particularly resistant materials must be used for such plants. Because of the large pipe diameters in the evaporators the cleaning balls have a diameter of up to 45 mm.
In the 70's as a further line the development was made of back rinsing filters, in order to protect the heat exchangers and condensers against rough contamination such as stones, fibers, plastic foils and shells. With the today's filters marketed by the enterprise the foreign bodies set off first on the filter surface. As soon as itself between filtering in and - withdraws by the contamination a certain differential pressure formed, the filter is rinsed. An electrically propelled rotor runs over the filter surface, with a piping with connection in the free is connected to which. In this piping is an armature, which is opened during the rinsing procedure. The accumulated dirt is sucked off and removed by this arrangement by the piping, which leads for its part behind the condenser which can be protected into the main cooling water line or however to a dirt collector. Also this technology found world-wide spreading in the power stations and industrial plants. The filters are manufactured dependent on the quantities of water in nominal sizes, which can be filtered, on DN 150 to DN 3200, the filter surface consist of stainless steel with punched holes. With difficult cases of contamination filter surfaces from plastic and gratings can be used. As a further design the enterprise manufactures fine filters with gaps from 50 to 1000
Since offered end of the 90's by the enterprise a further filter system, which already holds back contamination with the entrance into the Basis of conceiving this filter system was the consideration to already protect the entire plant equipped with it as well as its partial long pipings with the withdrawal of the cooling water against contamination. The system mentioned (Taprogge air Powered Intake system) is installed at the entrance of the cooling water pipe in free waters as housing with even filter surfaces and cleaned regularly by blowing out from an air supply line. Out stainless steel manufactured filters gets along contrary to the likewise used driving property goods under water without mobile parts and controls largest quantities of water. The filter surfaces consist of coated plastic and with bored holes are provided.
The Taprogge GmbH is regarded in its market segment as a market leader. Apart from the improvement of the efficiency of the power station process the decrease of the emission of carbon dioxide is the center of attention in fossil-fueled steam power plants at the customers of the enterprise. In world-wide about 90% of all steam power plants the cleaning and filtering units are inserted, in addition come a similarly high market penetration in the industry. The enterprise has its seat since 1984 in whom gladly, further branches with manufacturing plants is among other things in Japan, China and the USA. In over 60 countries agencies and addresses exist. A characteristic of the products of the company is their individual adjustment to the conditions of its customers. The products are projected as far as possible, designed in the own house and manufactured on 10.000 m resounding surface.
Since its establishment the company is as exempt private company in the property of the family Taprogge.
