[Equest-users] HIR-FPLR

I am looking at performance curves for Boilers in eQUEST, specifically Heat Input Ratio as a function of Part Load Ratio, HIR-FPLR. Can anyone please explain to me exactly how this works?

The curve has the form Z=a+bX+cX^2, where X is the part load ratio. According to the help files Z "modifies the fuel consumption". In what way does Z modify HIR?

Is HIR(X) equal to Full Load HIR divided by Z(X)?
