Boiler Blowdown Vessel Size Conundrums:

Does anyone have any hard and fast rules on boiler blowdown vessel
sizing ?
We manufacture a range of Blowdown receivers and supply then to a
broad spectrum of companies.
Many use their own rule of thumb methods for sizing and some more
technical - we ourselves aim within the guidelines of publications
like PM60.
HSE publication PM60 is mostly re-produced here and you will see it
leaves plenty to the imagination in reality:

Does anyone employ another method (without 6 pages of thermodynamics
calculations) that they find reliable ?
Many of our smaller clients and operators of steam plant seem divided
over the 'best way' - bearing in mind the larger the vessel is the
more it will cost, so if they don't offer like for like they could be
priced out of the job.
