Waste
Waste-to-Energy Calculator
Estimate thermal input and electricity generation from a waste-to-energy system using waste feed rate, heating value and conversion efficiency.
Use the lower heating value of the waste feed.
Electrical Power Output
–
Estimated electrical output based on the entered waste feed, heating value and conversion efficiency.
Thermal energy input
–
Daily electricity generation
–
Annual electricity generation
–
Electricity per tonne of waste
–
Annual waste processed
–
Method:
Thermal Power =
Waste Mass Flow x Lower Heating Value
Electrical Power =
Thermal Power x Electrical Efficiency
For waste entered in tonnes per day:
Mass Flow in kg/s =
tonnes/day x 1000 / 86400
When heating value is entered in MJ/kg:
kg/s x MJ/kg gives MW of thermal input directly.
Annual electricity generation =
Electrical Power x Operating Hours per Year
Electricity per tonne is calculated from the waste energy content and electrical efficiency.
This is a screening calculator. Actual waste-to-energy output depends on waste composition, moisture content, plant parasitic loads, boiler efficiency, steam-cycle performance, availability and operating conditions.
