  Methods for Calculating Energy Requirements for Processes

  Aug 22 2014  When a process involves both endothermic chemical reactions and heat generation from the combustion of fuels the choice of endothermic reactions to include in computing the energy requirement for the overall process is arbitrary and can be a source of confusion. It is shown that the essential question becomes whether the heat of combustion of

  How much hydrogen will be needed to replace coal in making

  Nov 04 2020  The energy value of the type of coal used for steelmaking is about 8 megawatt hours MWh per tonne.
