Research On Biomass Gasification Technology And Performance Of BIGCC System

Biomass is of interest as energy source because it is renewable, benefit to environment and would have no net carbon dioxide emissions associated with its use, therefore, research on biomass gasification and its power generation technology is of great significance. First, based on reading lots of references biomass gasification technology is discussed in detail including the basic principle of biomass gasification, categories and working principle of biomass gasification equipment and ancillary system of biomass gasification in this paper. Second, performance calculation modules of sub-systems such as gas turbine, heat recovery steam generator, steam turbine and dryer in the BIGCC system are built, especially, performance calculation modules of gas turbine fueling biomass fuel gas based on variable specific heat and biomass dryer are built. In the mean time, program of performance calculation modules for sub-systems is developed using Delphi 6.0. Finally, according to the national conditions in China and commercialized conditions of BIGCC system abroad, the configure schemes of two typical BIGCC system with capacity from 25 to 30 MW are presented, and system performance is calculated and analyzed, providing technical supports for optimizing performance of the BIGCC system later.Song Hongwei (Dept.of Thermal Power Engineering)...
