Gasification of lignite and wood in the Lurgi circulating

North Dakota lignite and wood chip residue (primarily Douglas fir from the US Pacific Northwest) has been gasified in Lurgi's 2 MW (thermal) CFB pilot plant at Frankfurt/M., W-Germany. Tests were carried out at various temperatures with air or oxygen as gasification agent for the production of fuel gas and synthesis gas, respectively.

GASIFICATION vs COMBUSTION OF WASTE/BIOMASS IN

Zeltweg Coal Boiler The Zeltweg power plant (137 MWe) was commissioned in 1962. In 1982 the nearby lignite mine was closed, and the firing system was converted to utilize hard coal (tangential firing). In 1989 a selective non-catalytic reactor (SNCR) was added to handle NOx emissions, and in 1994 the Lurgi CFB desulphurization scrubber was added.

Circulating fluidized bed combustion (CFBC) - ScienceDirect

Lurgi CFB boilers used an external heat exchanger (FBHE), whereas Foster Wheeler CFB (before 1994) did not. The differences between these two systems can be seen in Fig. 16.3 . Lurgi CFB boilers use a CFB loop with an external heat exchanger (FBHE) where about 20–60% of the total heat (excluding the boiler back pass) is absorbed.
