Which calorific value is same as the thermodynamic heat of combustion?

1.	Which calorific value is same as the thermodynamic heat of combustion?(a) Net calorific value(b) Flash point value(c) Gross calorific value(d) Fire point valueThe question was asked by my school principal while I was bunking the class.I'd like to ask this question from Calorific Value of Fuels in section Steam Power Plant of Energy Engineering
Answer» Right choice is (d) Fire point value Easy explanation: Gross calorific value is as same as the thermodynamic heat of COMBUSTION SINCE the enthalpy change for the reaction assumes a common temperature of the compounds before and after combustion, in which case the WATER PRODUCED by combustion is condensed to a liquid, HENCE yielding its latent heat of vaporization.
