Study on the Respirable Particulate Matter Generated from the Petroleum Coke and Coal Mixed-fired CFB Boiler

摘要：

The dust generated from the fuel combustion Is one of the important sources for air pollution. This paper has made a comprehensive research on the participate matter generated from the petroleum coke and coal mixed-fired circulating fluidized bed (CFB) boiler. Four kinds of ash were studied including the ash from the electrostatic precipitator(ESP), the ash from the bag filter, PM10 collected at the entrance of the ESP and the export of the bag filter. The results of the analysis of particle size show that PM10 of the entrance present the three peaks distribution due to the different formation mechanisms. The chemical composition analysis was conducted to deduce the formation mechanisms based on the current PM formation theory in combustion. The result indicates that there are two kinds of micron particles found, some are fuel generated, others are limestone generated. The bigger the particles are, the more limestone generated particles can be found.
