Gaseous products and particulate matter emissions of

Gaseous products and particulate matter emissions of biomass residential boiler fired with spent coffee grounds pellets. carbon monoxide PC ¼ Q comb LHV ð6Þ (CO) and volatile organic compounds (VOCs). NOx emission is good combustion efficiency. However, energy recovery was lower 201 ppm during SCG/sawdust blend combustion.

Development of Subair Technique for Combustibility

2019-4-1 · 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
