Anaerobic Digestion CHP

The anaerboic digestion CHP technology represents a two-stage biomass technology. In the first stage, wet biomass is digested to obtain biogas. This biogas is then burnt in a cogeneration device to co-generate heat and electricity.

The relationship between the in- and outflows is given by

\[\mathtt{v\_e\_aguc} = \mathtt{efficiency\_electricity} \cdot \mathtt{u\_wet\_bm\_aguc}\]

\[\mathtt{v\_h\_aguc} = \mathtt{efficiency\_heat} \cdot \mathtt{u\_wet\_bm\_aguc}\]

The symbols and names of the flows are

v_e_aguc_exp	Exported Electricity
v_h_aguc	Outflow Heat
v_e_aguc	Outflow Electricity
u_wet_bm_aguc	Inflow Wet biomass
