Study On Biomass Ash For Characteristics Of Dust Removal And Measuring Method

Crop straw is one of the main biomass resources in China, but at present, most of thecrop straw resources in China has not been reasonable used, the burning of crop strawbiomass fuel has a lot of harm, biomass power generation is an effective way of biomassRecycling used in our country. In the process of biomass power generation, biomasscombustion produces soot, sulfur dioxide and nitrogen oxides pollutants, and thesepollutions make huge harms to environment. Suspended particles of dust in theatmosphere surpassed a certain concentration can poison the environment, endangerhuman health. Therefore, making an effective control and prevention of dust frompollution sources is an important content of atmospheric environment protection. Thisrequests us testing and analysis chemical and physical properties of the fly ash materialin the process of power generation of biomass， and it has important theoreticalsignificance and application value to the pollution control.Based on the similar point of solid biofuels ash and coal ash about composition, thepaper offers testing programbased on to Chinese standard GB/T1574“Test method foranalysis of coal ash”，GB/T16913-2008“Methods of dust character test”，“Test methodsof fuel at thermal power plant” and EU standard DD CEN/TS15290, and assesses thefeasibility and precision of selected methods. The research result will provide for thefoundation of establishing Chinese national standard of solid biofuels ash analysis...
