| Abstract: | The present application state and existing problems on mechanical sampling facilities of furnace-incoming coal from middle part of the belt conveyor in one power plant have been analysed. Through increasing the opening size of sampling head, interlocking output signal of sampling head trouble with the programm control of coal conveyor, installing additionally coal plugging protector onto the bucket elevator, and allocating the by-pass, the improvement of design makes all problems to be solved. |
