Fuel-bound nitrogen

Most of the fuel-bound nitrogen is normally converted to mainly ammonia and smaller quantities of other gaseous organic nitrogen containing compounds (50-80%) during gasification of biomass. These compounds are all in the vapor phase and will therefore pass through all particulate removal devices and they will cause potential emissions problems by forming NOx, during subsequent combustion.

Biomass gasification gas as boiler fuel

1.2.3.1 The feasibility of biomass gasification gas as fuel As China’s energy situation becomes worse, the policy of national environmental protection has become stricter, and it is necessary to adapt to the actual situation of power generation tech­nology to reduce operation and maintenance costs (Dong et al., 2007). The safe operation of power generation enterprises has become more and more […]

Biomass and black liquor gasification

Klas Engvall, Truls Liliedahl & Erik Dahlquist 6.1 INTRODUCTION Modern society is profoundly dependent on fossil feed stocks to produce multiple products, such as transportation fuels, fine chemicals, pharmaceuticals, detergents, synthetic fibers, plastics, fertilizers, lubricants, solvents, waxes, etc., as well as heat and power (Demirbas, 2006). The fossil resources are not endless. Their price is increasing continuously due to increasing […]

Syngas combustion in practical devices

Syngas combustion in gas turbine engines (i) using an IGCC facility is quite promising for efficient, low-emission power generation, and for carbon capture and storage. Research in this area has focused on using syngas in natural gas-fired combustors (Monteiro, 2011). Similarly, some studies (Luessen, 1997; Colantoni et al., 2010; Boehman et al., 2008) have demonstrated the viability of using syngas […]

Results and discussion

3.13.1.1 Fuel properties Ultimate and proximate analysis (on an as received basis) of the DB (separated solids) used as feedstock in the current gasification experiments are presented in Table 3.3. Using as received analysis (ar), dry and dry ash-free (DAF) values are calculated and reported. Also, empirical chemical formulae are presented in Table 3.3 for gasification of DAF DB. Air […]
