[Gasification] Tom T's incredible "THERMAL" Gasifier

Wed May 2 20:09:16 CDT 2007

Hey Tom T -- just got around to checking your latest efforts -- really --
quite incredible!!

Some meat:

This system has operated for 1685 hours on various fuels, including tires,
press cake, cotton burrs, refuse derived fuel, poultry litter, and of that,
approximately 300 hours on cotton burrs during reactor and feeding
modifications to handle the burrs. Additional operations on plastic, waste
oils, tires, dried sewage sludge (30% moisture), and other feedstocks are
planned when the fuels are available. 

Specifics:
Kiln natural gas demand: 10mm BTU/hr. 24 hours/day 7 days/week.
Approximately 10 day downtime/year.

Well -- that gives something for the IC gasifier makers to aim for -- eh??

Marry it to an ORC Tom!!

And -- so happens I have been playing around with a very small
"updraft-thermal-gasifier design -- that also burns any kind of fuel -- and
kind of shape/size (as long as it can fit in the 6 in diameter body) and
humidities to 50% or better.

It runs on but a 24 watt blower to!

This part of the small ORC project I am always developing.

I really should post picture --

Easy to make -- fun to play with.

I just punched in "thermal gasifier" into the google search engine at the
Gas list site and got all of 13 hits!!

Amazing -- eh??

The really succesful side of biomass gasification is not a subject of
interest in this list!!

Commercial Operation of Thermogenics’ Model 103-2X-6 gasifier Update March,
2007
Leland Taylor, Thermogenics, Inc. March 2007

This photo shows the installation of the Model 103-2X-6 gasification system
at the Snyder Brick and Tile plant in Snyder, Texas. The fuel used at the
time of this photo is cotton "burrs" the husks of the cotton boll, leaves,
stalks, cotton, weeds and other cotton components gathered in harvesting
cotton using stripping. 

The fuel can be seen in the live bottom hopper on the right, a converted
truck road salt spreading unit. The material is fed into the system to the
right where it is introduced to the pressurized reactor through a
proprietary feeding system. From the reactor the gas goes through cooling
coils which also generate process steam, then to and electrostatic
precipitator, then to a water cooled heat exchanger to reduce the
temperature. From this it proceeds to a chiller to reduce the temperature
further then to the final electrostatic precipitator to remove the
condensed aerosols including water, organics and other contaminants which
may contribute to emissions or engine fouling. The gas is then fed to the
brick kiln through the pipe that can be seen on the wall of the brick
plant. There it is fed to the kiln in parallel with the natural gas burner
heads. Ash is discharged behind the feed hopper on the back-side of the
reactor. Ash is mixed in with the clay for brick making or sold as a
fertilizer if biomass is used. With the gasifier ash meeting US EPA TCLP
acceptance for landfill, it is not a problem to dispose of. 

This system has operated for 1685 hours on various fuels, including tires,
press cake, cotton burrs, refuse derived fuel, poultry litter, and of that,
approximately 300 hours on cotton burrs during reactor and feeding
modifications to handle the burrs. Additional operations on plastic, waste
oils, tires, dried sewage sludge (30% moisture), and other feedstocks are
planned when the fuels are available. 

Specifics:
Kiln natural gas demand: 10mm BTU/hr. 24 hours/day 7 days/week.
Approximately 10 day downtime/year.
Cost of natural gas $6-15/mmBTU. Operating cost: $60-150/hour, 350
days/year $511,200 to $1,270,000/year.
Current kiln replacement for natural gas, 30% with 1/2" pipes, to go to 80%
with 1" pipe upgrade.
Total system capacity is 1500#/hour of fuel which ranges from 80% of
natural gas usage to 180% depending upon fuel, cotton burrs 80%, tires 180%.
Electrical power for peak shaving power production: 200kW.
