Ignition enthalpy, flame combustion

Fletcher and Pilcher ( ) derived the enthalpy of formation by measuring the enthalpy of combustion of methyl chloride by flame calorimetry. They reported a value A H (CHgCl, g, 298.15 K) -19.59 0.16 kcal mol" where the error, according to the authors, is twice the standard deviation of the mean including the uncertainty in calibration, measurement, determination of ignition energy, and values of auxiliary data used. 

Equation 14.14, the critieal mass flux is a function not only of the critical heat flux at the siuface, but also of the convective heat transfer coefficient at the surface, the density and specific heat capacity of the combusting gas, the enthalpy of combustion of this gas and the ignition, flame and ambient temperatures which persist. Stoliarov and Lyon, [58-59] reported good predictivity of their model with respect to cone calorimetric mass and heat flux data...
