FIELD: transportation.

SUBSTANCE: in the device for pneumatic transportation of powdery substances from underground ash collectors, for each bunker, there are inlet branched pipes with a saddle on the inlet hole, trap with an air supply pipe, all mounted in a case. The case is joined to the transport pipe through the lower cavity. Each trap is installed in such a way that it can move from the saddle of the inlet branched pipe to the outlet end of the air supply pipe of the trap. The inlet end of the air supply pipe to the transportation pipe is joined through a distributing pipe, to the inlet ends of the air supply pipe of the trap and an air pipe, and through an electromagnetic valve to the receiver. The whole length of the transportation pipe is joined in sections, to the underground ash collector through cavities on the cases with traps and inlet branched pipes.
