Boiler feed water The so called „Boiler feed water“ is stored in a feed water tank and continuously feeded to the boiler of a steam generator. A big quantity of feed water is needed for example in steam power plants. The boiler generates steam, which is used for heating, for chemical processes or for driving a steam turbine respectively a steam engine. The feed water is purified in a way, that all harmfull components for the boiler are removed or neutralized. Leakages and evaporation loss are compensated by additional water which is purified in the same way than boiler feed water. Very often, valuable well and potable water resources are used for the generation of process water. Environmental regulations restrict this usage of well and potable water continuously and increase the costs for this resources steadily. The conditioning of stream water to boiler feed water helps saving potable water and means cost advantages. The process of conditioning is based on ultra filtration with down

"In phosphating, a phosphorus-containing crystal coating is applied to steel parts and galvanised steel parts by a chemical surface process. There are various phosphate processes, e.g., zinc phosphate, zinc calcium phosphate, iron phosphate. The coating thickness is adjustable for special customer requirements. Beim Phosphatieren steht die Verformbarkeit und die Bildung eines Haftgrundes im Vordergrund. During phosphating processes, the formability and the formation of an adhesive primer is of primary importance. The coating weight is usually in the range of 1 to 15g/m². Phosphatisations are especially resistant to lubricants such as oils or greases, and therefore well-suited to many technical applications. . Phosphate coatings are usually further coated. This involves: Oiling, soaping, lubricant coating, vulcanising and painting."
