·Biomass can become a stable and clean fuel after pretreatment namely biochar The mixing of biochar and pulverized coal can effectively improve the combustion characteristics of pulverized coal and increase the burnout rate of pulverized coal in the raceway [11] Therefore Pulverized Biomass Injection PBI technology has gradually developed into an effective
The primary air pollutants regulated from coal fired power plants worldwide are carbon monoxide CO sulfur dioxide SO 2 oxides of nitrogen NO and NO 2 which are referred to as NO X and particulate matter PM [] In general CO emissions from pulverized coal fired power boilers are low <50 200 ppmv as the combustion system tends to be operated with sufficient excess air
·Figure 10 depicts typical original measurement and fused velocities along with the WMA C C and rms charge level as a function of time for pulverized coal under an air velocity of approximately 16 m s −1 The arc shaped sensor arrays A C were selected as the measuring electrodes and the volumetric concentration of coal particles was %
·The forces of pulverized coal particles are very complicated and changeable during transportation this study used pulverized coal particles as transport materials to carry out transport experiments Computational fluid dynamics CFD method was used to model and analyze the flow of pulverized coal particles through the powder feeding pipe in
·The pulverized coal concentration of self preheating burner is generally around High pulverized coal concentration ensures that under ultra low load pulverized coal can be ignited more intensively thus ensuring stable combustion It will weaken the mixing of primary air and internal secondary air ensure the pulverized coal transport
