【摘要】 |
|
Numerical simulation and experimental study on NOx release along the boiler during pulverized coal combustion have been conducted. With the increase of temperature the NOx emission increased and the peak value of NOx release moved forward. But when the temperature increased to a certain degree, NOx emission began to reduce. NOx emission increased with the increase of nitrogen content of coal. The peak value of NOx release moved backwards with the increase of coal rank. NOx emission increased obviously with the increase of stoichiometric ratio. There existed a critical average diameter of the pulverized coal (dc). If d≤dc, NOx emission reduced with the decrease of pulverized coal size. If d>dc, NOx emission reduced with the increase of the pulverized coal size. The results showed that the simulation results are in agreement with the experimental results for concentration distribution of NOx along the axis of the furnace. |
