Dear @remp
please be noticed about steam temperature in addition to pressure, if your new device require colder steam you have also reduce its temperature.
in this condition a specific kind of valve with ability to inject water can help.
At the other hand you have to check the temperature...
Dear @DHURJATI SEN
Second configuration !, that means amount of phosphate in the water is monitored in the DCS system.
I think I should check the pump material and its compatibility with phosphate and also gather additional data.
anyway thanks for your comments.
regards.
Dear All
thanks for your kind replies.
@Dhurjati Sen , you are right, the problem is big enough to be followed by the top manager! I am sure that this information is not enough to make a proper vision.
but I really want to answer this question: Is there any corrosion issues for the pump...
Dear all,
Is there any consideration about injection of phosphate at Boiler feed pump inlet ( for an HRSG)? Does it have any influence on life time of the pump or corrosion issues?
In HRSGs phosphate is used to control Ph of the water to avoid flow accelerated corrosion (FAC).
Now we are facing...
Lets check the issue with another point of view!
from HRSG basic design point of view we normally first define the design pressure of the vessel/drum based on the maximum operating pressure, then this design pressure will be the MAWP of the vessel/drum.
after defining the MAWP of the drum...
Hi
I am not an Desuperheater expert but maybe following information be helpful for you:
1- we normally calculate water consumption of desuper heater in several HRSG load cases including the worst case ( maximum flow ) and minimum flow ( as a boiler expert )
2- when steam temperature is at...
Dear MJCronin
thanks so much for replying my question, as you mentioned Bacharach is the name of a company which is manufacturer of this kind of devices and its available in the market, as i searched through the net i found related standard, ASTM 2156 that clearly talk about this kind of manual...
Hello
I am responsible for HRSG basic design (Heating surface and so on), now we are facing some regulations from our licencor to consider some limitations when using fuel oil in gas turbine.
the licencor defined the limitation based on the BACHARACH INDEX of the exhaust gas of the GT,
does...
