I used Boiler #1 as my example because it had the out-of-the box settings that offered the most potential savings. Of note, though, is that this boiler has three pre-set reset curves, the most aggressive of which has a maximum HWST of only 120° F and puts the boiler in condensing mode of the time.

Boiler Efficiency | How to balance steam loads efficiently

Aug 26, 2011· The first step is to understand the load-versus-efficiency characteristics of a typical package boiler. Table 1 shows performance variation as a function of load. The boiler with an economizer generates 100,000 lb/h of saturated steam at 400 psig using natural gas. At load, the exit gas temperature is 320 °F. Excess air is 15%.

explanation of boiler efficiency curves examples in EP

Apologies for what is almost certainly a very dumb question but I'm struggling to understand what the boiler efficiency curves in the EP example files actually represent. Looking at InputOutput reference for the formula and plotting the biquadratic condensing boiler efficiency curve data given in the boilers.idf file gives Eff = 112% at 0.1 part load and Twater = 50oC for example.
