our present work is to study the effects of MgO, the specific
fuel consuming, and the hot corrosion effects on thermal boilers
and the SOX ,NOX compound produced in the exhausting
steam,(or gases).
When we visited the United Arab Company for Spinning and Weaving In the capital, Damascus, we found
a lot of problems in the units of feeding steam, and the most prominent of these problems occur corrosion
in the pipe of steam boilers, And the coll
apse in the heat exchanger on the thread dyeing machine (the
collapse of the body and pipes), so we took a group of samples in the places that suffer problems in order
to determine the mechanical and chemical properties, we found through analysis that the boiler tubes
were made of carbon steel, while the tubes and the body of heat exchanger was made of stainless steel, has
been shown through research that pipe boilers of carbon steel suffers of problems as a result overheating,
hydrogen damage and an attack Oxide, And the body of heat exchanger was suffering from an corrosion
Cracking result of the high proportion of chromium in it (chromium ratio up to 17%), has been
developing a set of solutions represented to be the metal surfaces clean and homogeneous, and must be
feed water free of salts, suspended solids, and gases
