cost of producing 600 psi steam vs 200 psi steam in boiler
(OP)
A boiler operating 24 Hr now produces 600 psi steam. If I need to use the same boiler for 200 psi steam only, how much minimum cost ( a factor like percent)in fuel cost, I can save?

Secondly, you are not supposed to run your boiler at a reduced pressure than it is designed for. There will be steam quality problems and also energy inefficiency(I am not speaking about energy consumption).

I can't think of too many plants that have tried this, that have actually had the headaches outweight the benefits. The ones that were convinced that they had acheived the greatest efficiency increases were typically being fooled by their steam meters.

I've seen that Spirax Sarco video and it is indeed dramatic. If energy efficiency and achieving maximum fuel value are your needs, then I would suggest looking up your local Spirax Sarco rep and having them in to do an energy audit on your plant. This is their bread'n'butter.

Besides the metering/measurement issues noted above, there are also some design issues/problems in the distribution system.
If we assume that the same massflow of steam is being delivered at a much lower pressure, the steam velocity will increase dramatically. This will cause erosion in piping, elbows, valves etc.
On the plus side, any existing steam leaks will npt leak as much condensate.
