How to Choose Industrial Boiler Cleaning Agent
Industrial boiler plays important role in the industrial and agricultural
production. However, boiler incrustation and corrosion will appear
unavoidably during its long-time running. Therefore, the regular cleaning is
necessary for the industrial boilers.Romiter Machinery, as an experienced industrial boiler manufacturer in
China, suggest that proper cleaning agent should be chose according to
the incrustation and corrosion.
Pickling agent
For the silicate incrustation produced by industrial boilers,we can
clean it by adding fluoride(such as hydrofluoric acid,sodium
fluoride,ammonium fluoride, etc.) in the hydrochloric acid.
For sulfate incrustation or mixed sulfate and silicate incrustation,in
advance,we should change their type by soda boiling,then,use the
hydrochloric acid or the hydrochloric acid added fluoride to clean.
For the iron oxide scale of industrial boiler,we can use hydrochloric
acid added fluoride or nitric acid to clean,the carbonate scale is often
cleaned by hydrochloric acid.
When the scale contains copper,the additives preventing the copper
plating should be added.Industrial boiler containing austenitic steel
material can not be cleaned by hydrochloric acid,generally,we can choose
EDTA, amino sulfonic acid, citric acid, formic acid, acetic
acid,hydroxy acetic acid as cleaning agent,and select the inhibitor and
additives containing no halogen element.
Alkaline washing agent
When a new industrial boiler conducts the soda boiling or the alkaline
wash before acid pickling,the alkaline detergent is generally composed
of sodium hydroxide and trisodium phosphate,or trisodium
phosphate,sodium hydrogen phosphate,wetting agent and other
additives.Industrial boiler containing austenitic steel material can not
choose the sodium hydroxide as its primary alkaline detergent.
When the industrial boiler in operation needs to clean the sulfate
scale and silicate scale,before acid pickling,the soda boiling is
needed.The alkali boiling liquid generally consists of trisodium
phosphate and sodium carbonate, or trisodium phosphate ,sodium
hydroxide,surfactant and other additives.
This is some basic methods to choose the cleaning agent of industrial boiler,if you have any questions about the ZG industrial boiler,do not hesitate to consult us,you are surrounded by the best service!
