Reconstruction of furnaces


The Cupola oven remains very economical melting apparatus meeting the individual requirements for quality castings, efficiency of melting and temperature of iron. The most common type is a cupola oven with a stream of hot air with or without subsequent thermal incineration. The exhaust gas can be flow off by vacuum system placed above feeding door.



The Columns are operated under reduced pressure. By lowering of pressure is reducing boiling point of compounds in the masut, so there is possible at 360 -400 ° C to distill futher substances. The upper part of the column divertes steams of vacuum gas oil together with water vapor and pass them through exchanger. In the exchanger these gases change their heat with masut oil and go into condenser operated at 30-50 ° C and further condensate the gas oil and some portion of water.

Interconnecting pipeline


The interconnecting pipeline serves for transport steam, water and other energy mediums in industrial applications. They are made of alloyed and unalloyed steels
internal deposition elements and suspensions
