![]() ![]() ![]() The boiler walls are provided with equispaced rams resting against the bottom of the headers of the tube banks. The pneumatic Rosink-Werkstätten rapping system SRS using single rapping cylinders is an automatically operating online cleaning system installed to increase the continuous operating time of boilers. Rosink-Werkstätten Single Rapping System SRS Rosink-Werkstätten Rapping Systems stand out due to a rugged design, low maintenance requirements as well as a less spare parts storage. Especially when there are numerous rapping points the cleaning by means of a rapping carriage is the more efficient and economical solution! The impact energy applied causes the vertically suspended heating surfaces to vibrate and removes the deposits. These special pneumatic impact cylinders rap on the reinforced caps of horizontally arranged headers. Depending on the arrangement of the tube bundles they are equipped with one or two superposed impact cylinders. ![]() One or several rapping carriages are moved from ram to ram. It is mainly used in case of horizontal boiler passes with suspended economizers. It cleans the heating surfaces of a boiler by rapping through specially formed rams on the lower headers. The pneumatic rapping gear type pKL is an automatically operating online cleaning system. An adjustment of the pressure and the amount of water and the selection of appropriate nozzles ensures that despite abrasive cleaning of the deposits the cleaning does not lead to increased wear of the boiler walls. This is clearly the best solution especially for bended feeding systems.Įven existing systems can be retrofitted with the Rosink-Werkstätten Water Spraying System without major modifications. This leads to significantly lower friction and lower wear of the hose. Due to the swiveling movement, the nozzle head is rotating during travelling into the boiler. The special feature of this solution is the special flexible hose that is lowered from the swiveling drum located above the insertion gate nozzle on the top of the boiler. 90° around the vertical axis and moved down and up, so the jets of water are describing a helical path in sectionally different levels during the cleaning process on the boiler wall corresponding to the respective boiler symmetry. In order to achieve a proper and complete cleaning, the nozzle head is swiveled approx. The simple and proven cleaning is carried out by four staggered water outlet nozzles that are offset by 90 degrees in two different levels of a nozzle head. This is especially the case for open passes of incinerators and their platen heating surfaces in the radiation path. ![]() The Rosink-Werkstätten Water Spraying System RWS also called „wet cleaning“ was specifically designed for the cleaning of those parts of the boiler that have been difficult to access so far. A comprehensive cleaning concept solves the problem of the flue gas temperature increasing in the convection part and also for the radiation paths. Heating surfaces continuously cleaned according to the cleaning concept of Rosink-Werkstätten will increase the boiler running time and optimize its efficiency considerably. These various systems clean the heat transfer surfaces during operation and maintain the efficiency, increase the continuous operating time of the boiler plants considerably and reduce the manual cleaning effort to a minimum. Heat Transfer Surface Cleaning covers the design and project development of soot blowers, water cannons, water spraying systems, rapping systems and shot cleaning systems. The range of products includes all types required for the cleaning of heating surfaces in power stations, heating and industrials boilers and incinerators. The Cleaning Systems Division of Rosink Werkstätten has been designing and producing a full line of Heat Transfer Surface Cleaning products since 1995.
