I have a question that maybe will be very easy for you. I am working on a district heating model using Dymola, and now I have to incorporate a boiler into my model, such as this one.
I was asked to present my results in the form of "energy curve consumption of the boiler" but I do not know how to get it, I have been reading about, but the concept isn't fully in my mind, can anyone help a little here?
Boiler efficiency curves are typically available from the boiler manufacturer, and will typically define the efficiency (ratio of output energy to input energy) as a function of flue gas temperature, return water temperature, loading (as percentage of full load), fuel type or some other operating parameter or combination of parameters.
A good primer for different variables affecting boiler efficiency can be found here- the Boiler Efficiency Guide from Cleaver-Brooks, a leading boiler manufacturer.
