This research aims to study the reduction of air heaters corrosion in
steam boilers and increasing their efficiency , by the application of
combined heating of air by steam and exhaust gases.
The experimental data of this research demonstrates tha
theater
corrosion could bereduced by maintaining the exhaust gases
temperature above the dew point of sulfuric acid depending onthe
amount of sulphur in the fuel oil ,by controlling air heat temperature
by steam.Which increases the boiler efficiency as a consequence of
reducing the fuel consumption by 9% as a maximum , reduces heat
loss, minimizes maintenance costs and reduces the time of emergency
shutdowns.
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

The study of the effect of the common addition of Syrian Clay
and magnesium oxides on the specifications of the resulting
cement stone and specifically its effect on the elasticity of the
resulting stone.
with advancing stages of oil production, the produced water ratio is
gradually increased, which provides favorable conditions for the
formation of oil emulsions.
The Mediterranean Diet is a healthy diet which protects from many
diseases, but many factors could affect the adherence and vary from
country to country. The purpose of this study is to assess the
adherence to Mediterranean Diet of the sample, the
n studying the
economic and social factors and lifestyle which affect the
adherence to Mediterranean diet. The sample was composed of
1000 people (516) women (484) men aged from 18-65 years from
all the economic and social levels, they filled a semi-quantitative
food frequency questionnaire. we used the SPSS program.
