Abstract :
The numerical simulation about CRF furnace combustion process was carried out by software Fluent if straw as reburning fuel and Ybaoshan lignite as the main fuel. Through regulating the air-coal ratio, the distributions of temperature and constitutive were acquired, and the reductive characteristic of NOx over straw was realized. The results revealed that: the fuel in main combustion zone could be burnt out and the temperature decrease in reburning zone was good for reduction of NOx; with the increasing of air-coal ratio, reduction rate decreased gradually; the reductive effect of straw was similar to that of micro-pulverized coal. Consequently, straw reburning to reduce the NOx discharge is feasible in power plant.
