Low NOx combustion and SCR flow field optimization in a low …

2018/8/15 · Low NOx burner redesign and deep air staging have been carried out to optimize the poor ignition and reduce the NOx emissions in a low volatile coal fired 330 MWe boiler. Residual swirling flow in the tangentially-fired furnace caused flue gas velocity deviations at furnace exit, leading to flow field unevenness in the SCR (selective catalytic reduction) system and poor denitrification efficiency.

Industrial Boiler Low NOx Combustion Retrofit Cost Algorithm …

For larger boilers, the burner pattern is estimated to be the same as that for pulverized coal. Another capital cost impact of NOX controls is the effect of staged combustion (both low NOX burners and overfire air) on packaged oil- and gas- fired

Development of Subair Technique for Combustibility Enhancement and NOx Reduction in a Pulverized Coal-Fired Boiler …

In this work, subair injection was proposed to improve the combustibility and NOx emission in a 500 MW tangentially fired coal boiler. The location of injection ports was determined based on the coal particle trajectory and its effect was investigated numerically. The flow rate of subair was set to 0, 5, and 10% of the total combustion air. The secondary air flow rate was decreased
