Re: [TRNSYS-users] Biomass Stove

["Chris Bales" <cba@du.se>]

Dear Arnaud,

there is also a TRNSYS component for small biomass stoves and boilers that
has been developed at our centre. You can read about it in the following
paper. 

Persson, T., F. Fiedler, S. Nordlander, C. Bales, et al. (2009) Validation
of a dynamic model for wood pellet boilers and stoves. Applied Energy 86(5),
pp. 645-656.

This model takes into account the heat transfer to the room, losses to
exhaust gas and thermal mass of the stove/boiler. However, it requires
measured data to get good parameter values, although values for a number of
stoves and boilers (Swedish) are published.

Best wishes

CHris Bales

Dear Arnaud,

I sincerely apologize for the delay of this email. Yes, you may use
Type121 or Type643. We also offer an individual component, Type967
(http://www.trnsys.com/indcomp.htm), that ramps up exponentially to its
steady state value. Neither of these furnace components considers the
transient gains/losses of the system when they are off. However, there was
a paper presented by a gentleman named Michel Haller at BS2009 who created
a TRNSYS component for biomass/wood/gas/oil combustion (for a boiler and
not a furnace). This component did indeed consider the transient effects
on the system during off periods.

Also, make sure you plug the output T, RH, and flow into VENTILATION in
Type56.

Best regards,

Matt Duffy

Good evening everybody,

I try to model a biomass stove. Is type 121 (or type 643-2 for TESS
librairy) is right for it?

Should I connect the output of this component to type56 via the convective
GAINS or via the VENTILATION?

Thank you very much for the help!

Best regards,

Arnaud.
