Atmospheric Fluid Bed Test Facility
Project Description:
Gasification testing, requiring approximately three times the fuel input per square foot of bed area to produce a fuel gas in the range of 200 Btu/SCF, is accomplished with smaller fluid test rigs available at our research center.
Pilot Plant Quotation and Information RequestIf you would like EPI to quote a pilot plant test, please fill in the following form as complete as possible, and let us know how to contact you.

on this Pilot Test
*Note: Fuel for testing should be shipped in 55 gallon drums or supersacks for ease of handling (other shipping arrangements can be made). No material in the fuel should be in excess of 4 inches in size. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Owner:
Our current pilot unit reflects our dedication to new fuels and markets with a 3' x 3'
square configuration (9 ft. sq. bed area) equipped with inbed and vapor space boiler tube
modules. The freeboard height of the fluid bed is 24 feet, providing two seconds of
residence time at typical vapor space velocities. Individually controlled overfire air
ports penetrate the freeboard at six elevations to facilitate combustion staging. A
seventh port, set near the outlet of the vessel, blends ammonia with the flue gas for
NOx
reduction testing. A close coupled hot cyclone follows the fluid bed combustor as a flue
gas pre cleaner for high ash fuels. In the case of high sulfur fuel testing, the cyclone
capture can be recirculated back to the combustion vessel as a hybrid design bridging
bubbling and circulating fluid bed technology for efficient SO2 reduction.
Flue gases leaving the cyclone are cooled for final cleanup in a baghouse. Gas sampling
ports located ahead and behind the baghouse facilitate third- party source testing to
collect emission data for new source permitting purposes. EPI also maintains CEM equipment
for real time emission monitoring of O2, NOx, SO2,
& CO during all pilot test projects. Pilot test programs
involving more than fifty different solid, liquid, and gaseous fuels and oil/gas co-
firing combinations have been conducted at the EPI research facility. The
combustion test
rig will accept up to 4.5 MBtu/hour depending upon fuel quality. Results from pilot test
programs have been the basis of design for numerous full scale plants that have ultimately
achieved both emissions and performance consistent with the initial pilot tests.
