The DB Riley LEBS design team included, as it does currently, Sargent & Lundy LLC of Chicago, Thermo Electron Corp.
For the DOE LEBS project, DB Riley drew on the related experiences of the advisory board it formed of major utilities, state energy and economic agencies, and research organizations.
The DB Riley team designed a 400-MW commercial generating unit of the LEBS that includes a supercritical Benson boiler fired with a low N[O.
We calculate that the net plant efficiency for a LEBS CGU firing high sulfur coal is 42.
8 pound per million Btu, eight times the limit set by DOE for the LEBS project.
Most of the LEBS tests at the Worcester facility used Illinois No.
This modified, or baseline, burner provided a comparison between the performance of the LEBS design and conventional U-fired boilers.
The results bore out the efficacy of the LEBS system.
Unburned carbon content can be further reduced in a commercial scale LEBS by recycling the fly ash into the firing chamber.
Once private funding is secured, DB Riley will construct a U-fired boiler, and a contractor will be selected to build the remainder of a commercial scale LEBS plant adjacent to the Turris Coal Co.
Then, too, we must maintain precise control of the combustion process within different physical dimensions than our research scale LEBS.
