The Detection Method Of Pollutants Emission Factors When Straw Burns Down In The Field

As the amount of China's burning straw in the field in fact is very big, the pollution caused by straw burning should not be ignored At present in China, the pollutants emission factors from straw burning are based on foreign data. That foreign data are greatly different has brought about certain difficulty for reference. In the project, pollutants emission factors from burning straw and influencing factors were analyzed by using two kinds of methods, one of which is detecting straw combustion to get pollutants emission factors in the laboratory open burning furnace that was designed on our own, and the other is burning straw whose weight is determined in the field, detecting pollutants emission concentration under the direction, calculating concentration of location of draw burning by using diffuse formula and finally calculating pollutants emission factors. The scientific methods for determination of pollutants emission factors when straw is burning in the field are summarized and the more reliable pollutants emission factors are detected in the paper.
