WebLHV = 50.025 MJ/kg. The LHV is calculated assuming that water remains in the gas phase. However, more energy can be extracted from the mixture if this water is condensed. This value is the higher heating value (HHV). The ideal gas mixture model used here cannot calculate this contribution directly. However, Cantera also has a non-ideal equation ...

WebHHV of Syn-Gas Description An analysis of syn-gas composition is required before calculating its HHV. The syn-gas is collected from the the gasification system process. Each sampling at the reduction zone must be consistently at the range of 750~850oC. The sample syn-gas is collected in a gas sample bag and then injected into GC for analysis.
