can you explain the concept and logic behind fixing of fixed (zero expansion)point in top supported boilers,how to find out it.is there any calculation for that?
OP you need to be more specific. What type of boiler, what fixed point are you referring to etc (fixing of the first tybe of the first pass in the radient cell pendant???), then maybe you will get somone who knows these boilers to give you some advice
Perhaps that is why the original post didn't get much response: the posting is too vague for the community to fasten on to what the original poster's needs are.
