Biomass-derived power, possibilities

A recent development has been the use of two-dimensional fluorescence spectroscopy as a new method for on-Hne monitoring of bioprocesses [108]. As ergot alkaloids fluoresce, the formation of the product during cultivation can be observed by two-dimensional fluorescence spectroscopy. Substraction spectra offered on-line real time information about the productivity during the cultivation. It was possible to follow the biomass concentration on-line by monitoring the culture fluorescence intensity in the region of riboflavine and its derivatives. This is a powerful application of this new sensor since the on-Une determination of biomass is extremely complicated for this fimgus. 

The use of tire-derived fuel as a cofiring feedstock in power generation has many advantages. Hrst, because of the high calorific value of TDF, particularly the wire-free TDF, the cost of TDF in GJ (ot /10 Btu) is lower than that of any fossil fuel - with the possible exception of Powder River Basin coal delivered locally or to a mine-mouth plant - and is competitive with even the lowest cost biomass fuels. This, combined with the lower ash content of TDF (without steel) makes it a viable blending fuel. In addition, the sulfur content of TDF is less than most eastern bituminous coals and conq>arable to medium-sulfur coals throughout the world.
