Application Report No. A 03-4e Page 1/2 Cleaning of pipes using the Tornado Status: 12/2004 PIOMAR, Poland / SS Cleaning of an ash transportation pipe in a power plant in Poland, using the KAMAT System "Tornado" Mainly in coal-fired and oil-fired power stations there is a recurrent problem of deposits blocking up the piping used to transport the ashes (from the boiler room to the dumpsite). Hard incrustations build up which narrow the tube inner diameter and making it necessary to increase the pump performance enormously, in order to flush out the ashes. In this particular case in a Polish power station, the incrustations are about 30 mm in thickness at the beginning, but further down the line, they reach a thickness of up to 70 mm.

Application Report No. A 90-4e Page 1/2 Cleaning a Conveyor Belt In The Fibre Glass Industry KAMAT Su Jeti The conveyor belts of a production line in the fibre glass industry become glued up in the course of time and have to be cleaned at given intervals. One possibility is to use a fixed installation comprising a traversing nozzle bar. However, in most cases the owners of the factories are reluctant to install such a system because of high investment costs and they prefer to assign the work to contractors. One of our Turkish customers carried out the work using a KAMAT high pressure pump type K 11026 A: Working pressure: 700 bar Gun nozzle: 1.5 mm Jetting angle: 15 or 30 Photo above: Conveyor belt before cleaning Photo on the right: The belt is cleaned with a gun and fan jet nozzle

Application Report No. A 04-4e Page 1/2 Pipe Line Cleaning KAMAT Su Jeti In all industrial processes the same problem arises: The necessity to clean pipe lines where, in the course of time, the internal pipe diameter has become narrower, due to deposits gradually building up. In the past, many companies used chemical methods to remove the incrustations. Nowadays, where environmental protection has become a serious subject, these old methods are hardly applicable any more. If chemical products are used today it is expensive to have them disposed of adequately, or to have them incinerated. Other companies saw no other possibility than to dispose of the blocked pipes at special dump sites and to replace them with new pipe lines. Using the KAMAT High Pressure Technology with a wide selection of special nozzles, the problems can be solved economically and without environmental pollution. Various cleaning methods can be employed, either manually or automatically (refer to our Application Report No. A 03-4). Photo above: The photo shows a pipe ID 100 in use in a plastics factory, blocked with plastic incrustations - prior to cleaning.

Application Report No. A 04-1e Page 1/2 Heat Exchanger Cleaning - Manual PTC, Italy In refineries and in petrochemical plants hundreds of heat exchangers (tube bundles) have to be cleaned every year. During the shut-down period where the time available is limited, very often fully-automatic cleaning systems are used (refer to our report A 04-2e). Whenever cleaning is required during the rest of the year, the work is carried out by contracting companies and is done manually. For instance, in a refinery in Turkey our customer is carrying out the work using a KAMAT pump model K 13024 A (1000 bar at 68 l/min). Photos on the right and below: The photos on this page show various types of tube bundles prior to cleaning. The deposits on the shell side (external) and the incrustations on the tube side (internal) are clearly visible.

Application Report No. A 03-5e Page 1/2 Cleaning of Boilers Flame-exposed Side KAMAT Su Jeti Cleaning boilers in power plants is a job which has to be carried out regularly. If the walls and the pipe bundles of the boilers are polluted, their efficiency will be reduced. To keep the costs of heating up the boilers as low as possible, these deposits have to be removed regularly. Worldwide, most of the power plants engage service companies to carry out the work. Such service companies make use of high pressure water to do the job. There are two possible methods of solving the problem: Either manually, using high pressure guns or semiautomatically using tank cleaning heads with guiding devices. Photos above: The pictures show a soiled boiler which has been turned off, before the cleaning work has been started.

Application Report No. A 03-1e Page 1/2 Cleaning of Condensers in Power Plants KAMAT Su Jeti Condensers in power plants need to be cleaned whenever the exchange of heat is no longer fully efficient. Previous methods used (drilling, brushes and chemicals) have meanwhile been replaced by high pressure water jetting. Using brushes or drilling caused damage or roughening of the surface of the tubes. Once the surface was roughened the build-up of deposits was encouraged, as they could adhere even better to the roughened surface. The use of chemicals is no longer economically justifiable, due to the costs and problems of disposal. The picture above shows the use of high pressure water on this application. Accessories being used - KAMAT Foot valve - Rigid hose DN 6 - Pipe cleaning nozzle ¼"
Application Report No. A 03-1e Page 2/2 Cleaning of Condensers in Power Plants KAMAT Su Jeti The picture shows the high pressure nozzle as it leaves the condenser tube. These are the parameter normally required for the job: Pump type : K 9000, K 11000 oder K 13000 Working pressure : 500 1000 bar Capacity per nozzle : 40 60 l/min.
