Abstract

The combined coal sampling equipment is essential to the representativeness of prepared coal samples in thermal power plants

its performance directly affecting safety and economic efficiency of power plants.Based on the structure of combined coal sampling equipment commonly used in thermal power plants

the affecting factors on deviation appeared in coal sample preparation by using combined coal sampling equipment of this kind have been analysed

the insufficiency in existing acceptance method being pointed out

and additional content for acceptance being put forward

so as to judge the source of errors.In order to present correct checking method

practical examples in acceptance of a combined coal sampling equipment have been given.
