Co-combustion of pulverised coal / biomass for steam production: emergy approach

摘要: Emergy, also called Embodied energy, has been firstly defined by Odum. It is the energy required to make a service or product expressed in of one form (here solar energy). Emergy per mass transformity (expressed as joule gram [sej/g]) varies from 0.88 109 sej/g for wood high 1.1 1015 coal. This concept eMergy particularly relevant compare on same basis different fuels especially analyse co-combustion renewable and non-renewable combustibles. The cost co-combustion, term emergy, makes it if collection biomass remains below threshold distance 400 km power plant. That can be raised 700 when calorific value feed stock higher.
