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

is a white, crystal powder with sour taste, that was found 1785 in apple juice. It is a chemical compound that occurs as left-turning L-malic acid and right-turning D-malic acid. In nature the L-malic acid occurs in unripe fruits to prevent to be eaten. During ripening malic acid is degraded. It is obtained by a chemical process from fumaric acid or maleic acid and is a mixture of D- and L-malic acid. The malic acid is soluble in water and in ethanol. The product results as an intermediate of the energy metabolism of every living cell. For humans it is one kg a day. The esters and salts are called malates.

Structure of germanBelt® steel cord conveyor belts Steel cord reinforcement: The standard steel cords have been hot-dip galvanised and have diameters from 2.6 to 12.8 mm. They are manufactured in 7x7 or 7x19 designs (other designs are possible). Their design allows good rubber saturation and distribution. Skim layers: A special chemical process provides excellent rubber/metal adhesion in the steel cord conveyor belt. The design of the steel cords leads to outstanding adhesion that surpasses any standards. Good rubber saturation and high adhesion on each cord provide germanBelt® steel cord conveyor belts with extraordinarily high longevity. Covers: The covers’ abrasion resistance, tensile strength and elongation value depend on the quality of the chosen combination of covers of the steel cord conveyor belt. Lateral reinforcements: The steel cord conveyor belts’ reinforcements consist of lateral steel cords with very high elasticity, or of textile fabric. The lateral reinforcements are worked into the carcass or the cover.
