    When should be the industrial boiler applied chemical cleaning?

    Thank you That’s right, but our feed water quality isn’t troubling now (Conduct:6~7). However the feed water quality was very worrying 4 years ago. Since we use dispersant based on inorganic phosphates, the deposits is soft and non- adherent. what is our problem? Thank you for your attention

    When should be the industrial boiler applied chemical cleaning?

    Thank you The analysis of deposit follow as: Cao: 31.8 wt% P2O5: 20.3 wt% Fe2O3: 33.6 wt% SiO2:5.6 wt% MgO: 5.2 wt% Best regards

    end cold corrosion

    Thank you It is good idea, but it is very costly. is there any Commodious ideas? Is any coat used? Do you know suitable coat? Regards

    end cold corrosion

    Thank you I want to get the accurate amount. But it is suitable,too. what material do you suggest to use in economizer where condensate of H2SO4 occur?

    end cold corrosion

    Thank you I read this article exactly. In the first page, there is a diagram need amount of SO3 and H2o, but it is impossible to measured amount of So3 for me. Is there any way for calculate dew point of H2SO4? Regards

    end cold corrosion

    Thank you gr2vessels That's right. so, I Don't need amount of So3??? I found a diagram for dew point of H2SO4, but this needs amount of H2O and So3. Thank you again

    end cold corrosion

    Hi guys I want to calculate dew point of H2SO4 in the duct of boiler but I have just amount of So2, Co, Co2, O2. Is it possible to calculate dew point? Thank you

    The real- time of corrosion monitoring

    Thank you very much Your opinion is completely right. Our chemical process is very variety. for example, according to design, a thickness of pipe is 5mm and corrosion allowance is 1.5mm. At first UT inspection that apply 4 years after start of process, the thickness of pipe is measured 4mm. Does...
