How to calculate lhv from hhv
WebLHV vs HHV Efficiency. When it comes to defining operating efficiency, Thermal Fluid Heaters are often rated by either Low Heating Value (LHV) or High Heating Value (HHV). The difference in efficiency ratings is determined by whether the water vapor produced during the combustion process is factored into the calculation. Web7 apr. 2011 · However, I can see the LHV when I do the following method. 1. Right click on the stream and select show table 2. Right click on table and Select View Properties 3.
