@AntoineGautier, could you please create a branch issue2290_steam_boilers from master for these developments? Thanks

Hi @AntoineGautier, I believe we should be able to use this old branch still for the steam boiler models. If you agree, could you please pull the changes from the master to this branch so that it is up-to-date? Thanks!

@SaranyaAnbarasu: just copying you here as well so that you are aware of the status.

[AntoineGautier]

@khinkelman Correct, you can start from this branch that is now identical to the master.

(base) ~/gitrepo/modelica-buildings[issue2290_steam_boilers]$ git diff origin/master
(base) ~/gitrepo/modelica-buildings[issue2290_steam_boilers]$

• [ ] Note: a lower bound should be set for the fuel to air ratio to avoid division by zero error.

See below as an example:

// To compute the electrical power, we set a lower bound for eta to avoid
 // a division by zero.
 PEle = WFlo / Buildings.Utilities.Math.Functions.smoothMax(x1=eta, x2=1E-5, deltaX=1E-6);
 eta = etaHyd * etaMot;

Closing since https://github.com/lbl-srg/modelica-buildings/pull/2961 is now merged. @khinkelman Let me know if this should not be the case. And thank you for your efforts and contribution here!

Many thanks @dhblum for your time and efforts to complete these tasks! All work for outstanding steam district heating issues is complete from my end. Thanks for closing the related issues.
