[TRNSYS-users] Problem in STEC Library- Rankine cycle

[David BRADLEY]

Christina,
   The STEC library is provided to the TRNSYS community "as is." The 
library was developed by an organization of  research groups called 
SolarPACES (http://www.solarpaces.org/inicio.php). The last version of 
the STEC Library for TRNSYS was released in 2006 and while the library 
is still available, the SolarPACES groups' activities have moved in 
other directions. To my knowledge there is no one actively supporting 
the STEC Library anymore.

   There are other sources of components that might be worth pursuing. 
The TESS Cogeneration/Combined Heat and Power library contains a number 
of steam components and includes a steam boiler among them. That model, 
however, does not allow for different fuel compositions and does not 
compute CO2 emissions.

   You might also pursue leads from a paper that was presented at the 
IBPSA World Conference in 2009: "COMPARISON OF DIFFERENT APPROACHES FOR 
THE SIMULATION OF
BOILERS USING OIL, GAS, PELLETS OR WOOD CHIPS"  
(http://www.ibpsa.org/proceedings/BS2009/BS09_0732_739.pdf )

Kind regards,
  David
