�����������
A typical application in powerplants is pulverized fuel piping,here protected by ABRESIST
Reduce Costs andAvoid Downtime
Large quantities of bulk materialare handled in the conveying andstoring systems of coal firedpower plants. Unless they aresuitably protected these systemswill experience frequent failurerequiring repair or replacement.Kalenborn offer the completearray of wear protection materialsincluding not only ceramic andmetallic materials but alsoplastics and rubber.
In addition, Kalenborn haveextensive experience in the fieldof slide promotion. Interruptionsof material flow inside of bunkersand silos must be avoided andKalenborn cover the entire mate-rial range with plastics as well asmetallic and ceramic materials.
In any case we can supply atailor-made solution for yourparticular problem. Our expertsare prepared to be of assistance.

Fly ash pipes are among theplant components that areparticularly endangered bywear. Kalenborn offer a varietyof materials to ensure optimalservice lifetimes: ABRESISTfused cast basalt, KALCORzirconium corundum andKALOCER high aluminaceramics.
ABRESIST fused cast basaltis the accepted standard for
piping in wet ash pipe systemsall over the world. The picture
shows a plant in India.
Coal bunkers require a reliablematerial flow. This is ensured bythe use of KALEN slide promotionplastics. Slide promotion steel -perhaps combined with KALEN -will be best in case of moreintense wear.
Reliable wear protection is ofparticular importance for
trouble-free continuousoperation of the coal injection.

Plant components are at risk in all power plantsystems, especially in coal storage and coaltransport. This includes coal pulverizing andinjection into the boiler, dust collection andash removal including fly ash and wet ash.The situation is similar for limestone andgypsum in desulphurization systems.
Service lifetimes of many years are oftenachieved with the following materials:
� ABRESIST fused cast basalt� KALCOR zirconium corundum� KALCOR-S sintered zirconium corundum� KALOCER high alumina ceramics� KALCRET hard compound� KALSICA silicon carbide ceramics� KALMETALL-C hard casting� KALMETALL-W hard overlay welding� KALINOX slide promotion steel� KALEN slide promotion plastics
In addition, material combinations have beenvery successful in practice. They enable bothtechnically and economically optimal solutions.

Jointless lining with KALCREThard compound - also possiblewith asymmetric cross section
Kalenborn have extensive experi-ence and offer a complete range ofsolutions for PF-pipe. With diame-ters between 400 and 800 mmmany possible combination liningshave been used in practice.
Depending on the specific opera-ting conditions (such as particlesize, ash portion, volume to beconveyed and transport velocity)successful designs have achievedservice lifetimes of more than10 years.
KALCOR-S allows the use of largelining segments, thin walls andhomogeneous structure
Material combinations of KALCORand ABRESIST provide economicwear solutions
KALCOR zirconium corundum lining and unlined transition elements;488 mm diameter
Long lifetimes at favorable costs are achieved with KALMETALL-C hardcasting; this example shows 518 mm diameter bends up to 700 kg weight

KALMETALL-W hard overlay welding enables the production of self-supporting structures for PF-bends without an additional lining

In the last 50 years Kalenbornhave supplied many thousands ofmeters of wet ash pipes to plantsall over the world, normally linedwith ABRESIST fused cast basalt.This material has proven to be anexcellent choice for this particularapplication.
ABRESIST combines the proper-ties of high wear resistance andhigh corrosion resistance. Theservice lifetimes of these pipingsystems frequently cover morethan 20 years. There is no othermaterial that has reached similarservice lives in practice.
Kalenborn offer wet ash pipes ofmany different configurations withinside diameters between 200and 500 mm. The steel casingcan also be efficiently protectedagainst corrosion.
The pipes are usually joined byflanges. However, any type ofcoupling is feasible. In addition,welded and screwed joints haveproven successful in practice. Pipes in Australia;
the pipes areconnected by"Victaulic"couplings
Wet ash pipe in NorthAmerica; the pipes areflanged together
Erection of wet ash pipes inMalaysia (350 mm diameter)
Long pipes require the use ofexpansion joints for compen-sation of length
