PURPOSE
Screen an industrial biomass CHP proposal against the site's useful steam
and electricity demand. Complete with the energy manager, process engineer
and supplier. Use current project documents; this is not a plant design.

SERVICE AND CONDITIONS
Site/process and reviewer:
Steam pressure, temperature, flow and reference conditions:
Hourly/seasonal steam and electrical demand data source:
Operating hours, shutdowns and backup steam source:
Turbine arrangement and part-load performance source:

BALANCE — all values must use one declared boundary
Fuel energy input (MW), lower/higher heating value basis:
Gross electrical output (MW):
Plant electrical auxiliaries (MW):
Net electrical output = gross - auxiliaries (MW):
Useful process heat delivered (MW thermal):
Combined useful efficiency = (net electricity + useful heat)/fuel input:
Simultaneous site electrical demand, imports and possible exports:
Annual energy: integrate power over time; for constant power, MW x h = MWh.

FICTIONAL CHECK
Fuel 20 MW LHV; gross electricity 4 MW; auxiliaries 0.5 MW;
useful heat 10 MW. Net electricity = 3.5 MW; efficiency = 67.5%.
At 7,000 constant operating hours: 24,500 MWh net electricity and
70,000 MWh thermal useful heat. With 3 MW simultaneous electrical
demand, 0.5 MW remains for possible export, subject to connection terms.
These values are invented; do not substitute them for a supplier model.

FUEL
Suppliers, annual schedule and competing uses:
Delivered wet tonnes; moisture by mass; dry matter; heating-value basis:
Fictional check: 100 wet tonnes at 40% moisture = 60 dry tonnes;
at 50% = 50 dry tonnes, 16.7% less dry matter. This alone is not usable heat.
Contamination, particle size, quality sampling and rejection criteria:
Storage, handling, access and contingency supply:

ENVIRONMENT AND DECISION
Air permit/ash review owner and relevant authority:
GHG comparison: feedstock origin, alternative fate, land carbon, transport,
processing, displaced energy and time horizon:
Current financial inputs and sensitivity to hours, fuel and downtime:
Accepted evidence:
Open issue | required document/test | owner | due date:
