Abstract

Some specific bamboo pellets were combusted in a tube furnace individually in different constant air flow rates (3,4 and 5 L/min) and at various temperatures (800, 900, 1000, 1100 and 1200 ), in order to investigate the dynamic emission characteristics during various respective combustion processes. The results indicate that the increase of carbon monoxide(CO) amounts in 3 L/min air flow rate was caused by kinetic controlled combustion at 800 and by diffusion controlled combustion at 1100 and 1200 . The yield and concentration of nitric oxide(NO) reach the maximums at 900 , as well as the conversion rate from fuel-N to NO (9.17%). As combustion temperature increases, the yield and concentration of NO decline from the peak, and the conversion rate (from fuel-N to NO) falls to the lowest value (3.90%) at 1200 in 3 L/min air flow rate. When a bamboo pellet burns sufficiently almost none sulfur dioxide(SO2) was released , while the S element can be kept in the ash or discharged in high-temperature flue gas in the form of sulfate which is converted from fuel-S. In oxy-lean atmosphere, SO2 generates from the decomposition or oxidation of organic S during early devolatilisation, wheares more fuel-S probably are released in the forms of H2S and CaS.
