MSW to Electricity
The DuTemp Plasma
Conversion System exploits the unique capabilities of plasma
generating systems by integrating them with associated technologies
to realize the latent value in the municipal solid waste stream.
Plasma Generating Systems have, at their core, the capacity
to dissociate compounds into elemental atoms.
Once the atoms are free to move independently, simple
chemistry is applied to reassemble the atoms into usable,
commercially viable products.
DuTemp brings a number of proprietary technologies involving thermal
plasma that through their unique application provide the most
efficient method of generating synthesis gas.
The important difference between the DuTemp Plasma Conversion
System and other plasma designs is our ability to deliver municipal
solid waste into the reaction chamber not only without air, but also
in a continuous, controlled supply at controlled density and in
large volumes (2000, 3000 or 4000 tons per day).
This ability results in a superior synthesis gas product with
higher BTU
energy value
and
also makes the process economically feasible.
Solid municipal waste disposal requires the ability to
process not pounds but tons per hours.
The
organic content of average municipal solid waste will dissociate or
thermally depolymerise into 30,000 to 33,000 cubic feet of synthesis
gas per ton, having an energy value of 300 BTUs
per standard cubic foot of gas.
The heat rate for DuTemp combined cycle power generating
system is expected to be about 7.277 or lower, generating 1,360
Kw
per ton of municipal solid waste that is processed.
The processing of 1000 tons of municipal solid waste per day
or 41 tons per hour will release 1,353,000 cubic feet of synthesis
gas per hour with a total BTU
value of 405,900,000 BTU/hr.
At a heat rate of 7,277 the DuTemp combined cycle gas turbine
system will generate a gross of 55.76 Megawatts of electricity per
hour, twenty‑four hours a day.
When we deduct 26 Megawatts of this electric current to
maintain the plasma arc and for other plant requirements, we are
left with 29.76 Megawatts per hour (714.24 Megawatts per day)
available to supply the grid.
Relevant Experience of Power Generation Utilizing Synthesis Gas:
The
DuTemp technical team will utilize General Electric gas turbines
(however, some other heavy frame and aero derivatives can also be
used) for producing electricity.
GE brings over 600,000 hours of operation on syngas, clearly
enough to establish that the basics of syngas utilization in
combustion turbines for electric power generation in simple or
combined cycle modes are doable.
In fact, in Europe over eleven Gigawatt hours of power are
produced using syngas.
Most of this is from conventional gasification methods.
The main reason this has not been common in
GE's
success with low and medium BTU
fuel gases is
the
result
of extensive full‑scale laboratory
testing on various fuels for over 15 years at GE's
