(OP)
Is a blowdown tank required for a 20 bhp 100 psi boiler required by the ASME? Installer says that it can be blown down into a pail and the water than dumped provided the temperature of the water is under 180 deg.





RE: Boiler blowdown tanks
Can you let us know what type of boiler is it? I'd suspect small firetube or an electric? Is this blowdown intended to just reduce the TDS in the water or is it intended to removed an settled solids? What is the blowdown flow rate?

First, I doubt the ASME code requires a blow down vessel though it would likely govern the design if you selected one. There may be other regulatory bodies that might, this is way outside my area of knowledge.
However, I doubt I would want to blow this boiler into a bucket from an operating and safety point of view. Ask the manufacturer for a user reasonably near you (if one is available) that you can go visit and watch. At the least, phone a user and talk to them how they do it and then what you want. Sorry, I know this isn't the most specific advise.
