Biomax 25
Biomass Project
Sponsored by USDA
3 year project, begun 10/2006
Utilizes Community Power Corp.’s BioMax® technology
Custom-built portable trailer
$500,000 for BioMax & trailer
Convert wood residue to
Electricity
Thermal (heat) energy
Project Concept:
Is it economically viable to transport portable distributed energy generators into locations that are producing biomass residues?
BioMax 25
- 25 kilowatts electrical
= 200,000 Btu/h heat
- Elec. & heat energy for 15 avg. MT homes
- 50 lbs/hr wood chips
- 1,750 scf/h prod. gas
- Char/ash production 0.75 lbs/hr
- Soil amendment
- 70% overall efficiency
Fuel Equivalents
1 hr operation = 50 lb wood = 400,000 Btu
= 3.3 gal gasoline
= 8 gal diesel
= 4.5 gal propane
= 2.9 gal crude oil
= 33.3 lbs coal
= 387.9 cubic feet natural gas
BioMax Emissions
Complies w/ CA air stds
