[Equest-users] Steam Boilers

[Michael Andelman]

Unfortunately you need some water flow in the loop.  If all heating is by
steam add a dummy zone with some small HW heating load.

Hi Katie,

 

Zero experience designing/modeling steam boiler systems, but I see an option
to create a steam boiler in both the detailed and wizard modes.

 

Creating a dummy forced draft steam boiler in wizards makes a boiler/HW loop
with starting setpoints of 230F/180F, and a help file says the larger of the
two will be used - 230F looks something like a steam temperature to me, so
it appears to be a steam loop in function, if not in name...  I see a
default pump is added from the wizards - not sure whether one can remove
that without causing errors, or even if you should.  My rudimentary
understanding of steam distribution is that there is no explicit pump/fan
for circulation - the steam boiler provides the pressure?

 

I'd be very interested for someone with more experience to chime in on this!

Has anyone had good luck with modeling steam boilers?  It seems odd that the
only loops that can be created are HW loops.  There's no such thing as a
steam loop in eQuest.

 

Thanks,
