[Gasification] CONSERVATION OF ENERGY

[Thomas Reed]

PS. 

According to my book, THE FREE ENERGY OF BINARY COMPOUNDS (available at Woodgas.com)

The Enthalpy of combustion of Al 

Al + 3/2 O2 ==> 1/2 Al2O3.   Delta H (C) = 178 kcal/mole = 745 kJ/mole.  The MW of Al is 27, so this is 27.6 kJ/g or 12,527 kJ/ lb.  1 kW hr is 3.8 MJ, so this is 3.3 kW hr/lb. 

Well worth capturing.
