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
Lbs/kWh
NOX 0.00065
CO 0.0000295
VOC 0.000031
PM2-5 0.0003
PM10 0.0000
CO2 7.7260
Hg 0.0000
Pb 0.0000
SO2 <0.0030

My truck is a dual fuel truck. I can run on wood or gasoline. I am now working on a hybrid mode, I purchased a chip and chip burner from moates.net and am using Paul Booths ECC Editor to work with my fuel injection and spark tables to allow me to meter in some gasoline for better acceleration and to make up for any varying woodgas production conditions. Many thanks are due to Paul Booth for not only writing the ECC Editor program but for the time he personally put in making a definition file for my trucks ECC. The process of running in a hybrid mode is still in the development stages, I have met with some success. This page will be updated as things progress.

Gasifier and Engine Tables
Kevin Chisholm, October 11, 2006

Attached is a Spread Sheet "Gasifier and Engine Tables" that should answer a number of questions relating to diesel fuel displaced by using wood gas in a dual fueled engine, or the amount of wood required to provide sufficient gas to run a Spark Ignition (SI) engine of any size.

I put this Spread Sheet together, based on fundamental work done by Doug Williams of Fluidyne, www.fluidynenz.250x.com

Enter the engine speed in the colored block, in Table 1, and this gives results for an engine of 1000 cc displacement. In Table 2, the engine displacement can be entered, and this table gives the expected results for an engine of that displacement.

For a given engine size, if you know its petrol consumption now, the Table 2 would tell you how much wood you would require to operate the engine under similar load conditions. I hope you find this helpful

Best wishes,

Kevin

From "Classic Bike" 2002 August page 45 I am not sure how to make the image available large enough for people to read, perhaps Ill attach it as an attachment, I think that will make it display larger when downloaded?
