Boiler and Condenser Pressures - Rankine Cycle | nuclear …

Boiler and Condenser Pressures – Rankine Cycle. As in the Carnot, Otto and Brayton cycle, the thermal efficiency tends to increase as the average temperature at which energy is added by heat transfer increases and/or the average temperature at which energy is rejected decreases. This is the common feature of all thermodynamic cycles

Is a high efficiency, condensing gas boiler the best choice for my home? | U.S. Boiler …

2018/8/13 · In comparison, a condensing boiler may provide up to 96% efficiency, which means that only 4 cents of heat escapes. That's a big difference! It may seem hard to believe, but upgrading from a typical 80% efficient boiler to any condensing boiler in U.S. Boiler Company's extensive line can provide a 15-20% savings in energy.

Getting the Most Out of Your Commercial Condensing Boiler

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. If you take the time to read the manual, you might find that you can do away with that pesky math or that clunky ruler by simply using an already built in reset curve.
