• We tend to prefer

projects which remove recyclable materials, and non recyclable materials .

• We can't gasify stone

and glass, and we should recycle aluminum cans, etc. 4

• Transfer to Waste Processing can be direct or

by trans shipment .

• Baling systems can produce wrapped waste

with NO odor and NO negative image. 5

• 4 V is u a lly

• Bales weigh

approximately 3,500 pounds each.

• Compressed

approximately 14:1 ratio.

• Can be stacked

deeply, and held in high temperatures without problems

F e a tu r e s , 1

• Four air sources:
• Underfire air gasifies biomass in the pi stage
• Overfire air preheats 1'1 stage producer

gas to ensure ignition in the 2nd stage

• Primary combustion air ignites the preheated

producer gas at the bottom of the 2nd stage

• Secondary combustion air completes

combustion of producer gas in the 2nd stage

'4 Significant Featnres, 2 ~

• Very large pt stage grate area
• Hence grate temperature

:5:1,200°F

• Hence essentially zero slag
• Ash can be reclaimed as valuable products
• Very low underfire

air flow

• (only need sufficient air to gasify biomass)
• Hence very low particulate elutriation off

pile

~ Significant Featnres, 3 In

• The Biosphere Gasifier can burn biomass with

moisture contents up to 65% (wet basis) and ash contents up to 35%

• 5:1 turndown

• 15 second

• Reducing the greenhouse gas effects of

the combustion of fossil fuels is exactly the value produced by a biomass and refuse derived fuel based power plant .

• ZERO "new" C02 production cycle.

• '4 Biosphere Gasifier
• 1st Stage: gentle

updraft gasification

• n very

large grate

• 2nd Stage: vigorous,

double vortex, cydonic combustion

• Emissions (untreated):

CO < 1 DDm. NOx< 15

• DDm. Darticulate

< 100 ma/Nm3 (< 0.125 Ib/l06

Btu: < 0.04 ar/dscfl

• Emissions listed are Drior to treatment.

Bag House @ PM2.5 and Wet Tubular Electrostatic Precipitators are planned for projects.

• Units in continuous
• peration

for 25+ years

4Significant Features, 4

• Staged combustion permits operating

with excess air levels as low as 15%

• The lime kiln test unit burned 55 %

moisture content hog fuel and supplied 2,200°F flue gas to the kiln @ e = 15%

• Stal!:edcombustion and low temperatures

(due to wet fuels) combine to produce virtuallv zero thermal NOx

I

4 Significant Features,S

• Dioxins and Furans Destroyed, viz.,
• Chlorine can react with cellulose to form

dioxins and furans in the 1<1 stage

• However, these gases are destroyed in the

2nd stage with its 1,800°F plus brick walls

• No black waterwalls are present to chilI •

and lock in - dioxins or furans in the 2nd stage

M.A.C.T . ~ Dioxins & Furans

• M.A.C.T. is maximum available control
• technology. (Also sometimes known as B.A.C.T.
• r Best Available Control Technology) •
• While we should not have any issue with this on
• ur gasification, we include special bag houses

that would automatically catch any dioxins or furans at 40% below the current A7 Ontario Standards. Very, very clean.

Idaho Notional laboratory

M .A .C .T .

• The Idaho National Laboratory

has come up with a way to insert a "re-burn" chamber for NOx on the exit ducting of our gasification unit.

• Given the low proteins in municipal waste

product and very low thermal NOx this would be a very conservative move that we would do more for "PR" than any need -but this is a test we are interested in and will pursue.

~Agricultural Wastes ~

• With a grate temperature
• f 1,200°F, potassium

(potash) and sodium (soda) in agricultural and animal waste do not vaporize to form alkali deposits on boiler tubes

• Potassium vaporizes at 1,400°F and sodium

vaporizes at 1,616°F

• The potash and soda remain in the 151 stage,

from which they are removed by the built-in ash removal system and sold to farmers depending on what else is present
