• Resumen

  • The emissions of NO, N2O, CO and SO2 were investigated during combustion of wood in a circulating fluidized bed boiler as a function of various parameters, including bed temperature, air supply and load. Emissions from mixtures of wood and coal were also investigated. The results show that the nitrogen oxide emission is directly related to the nitrogen content of the wood. The small amount of char in the bed during combustion of wood results in a much smaller reduction in the NO formed in the case of wood compared to that during combustion of coal and reduces the impact of bed temperature and air supply on the NO emissions during combustion of wood as compared to coal. Emission of N2O during combustion of wood was negligible.
