Abstract：Combining with the work process of sampling machine,and from aspects such as basic parameters,sampling machine parameters,sampling plan design,parameter calculation,parameter calculation in sample preparation plan and belt coal stream sampling machine configuration,the belt coal stream sampling equipment was introduced,moreover,from aspects like sampling unit amount,increment amount of sampling unit,increment and gross sample weight,increment interval,the design of belt coal stream sampling plan and relative parameter calculation were analyzed particularly.Additionally,in this paper,from aspects such sampling method,sampling unit,increment amount of sampling unit,gross sample weight,primary increment weight check, sample preparation system matching and calculation,car and box car sampler configuration,the car and box car sampling equipment and its calculation result of functional parameters in every term were demonstrated.Regarding to the sampler site condition and unit capacity,the configuration plan of sampler was discussed,it was suggested that sampling machine of coal fired generating unit should be set according to the type of incoming coal and how the coal comes.
