Abstract

Fixed-bed combustion of straw has been conducted in a 15 cm diameter and 137 cm long cylindrical reactor. Air, which could be preheated, was introduced through the bottom plate. The straw was ignited at the top with a radiation heater. After ignition, when a self-sustaining reaction front was attained, the radiation source was removed. Temperatures were measured at 8 locations inside the bed, and the concentrations of O2, CO2, CO, H2O, CxHy, NOx, and NH3 were measured at the location of the upper thermocouple, i.e. 30 cm under the top of the bed. Air velocities of 6, 10 and 15 cm/s (Standard Temperature and Pressure) were used, air temperatures of 20, 150 and 200°C, and as bed material finely cut straw (dp
