Higher heating value lower heating value
Did you know?
WebFor gross (or higher) heating value, the water produced by the combustion is assumed to be recondensed to liquid. For the lower (or net) heating value, the water is assumed to remain as gas. Since all engines exhaust water as a gas, net heating value is used for comparing fuels, while assays typically report gross heating value. Webbetween the lower heating value of a fuel and the higher heating value of that fuel is: LHV = HHV – 10.55(W + 9H) Where: LHV = lower heating value of fuel in Btu/lb, HHV = …
