Pellet transfer system

Disclosed is a system for transferring fuel pellets from one container which may be at a location external to a building to a second container which may be at a location in an interior of the building. The system may include a first container positioned at a location remote from the building and a second container positioned proximate to the building. The first and second containers are connected to one another to permit the transfer of fuel pellets from the first container to the second container by a pneumatic apparatus.

Boiler system

本发明涉及锅炉技术领域，特别涉及一种锅炉系统。本发明所提供的锅炉系统包括：第一一次风管；第二一次风管；和煤粉输送装置，连接第一一次风管和第二一次风管，并将第二一次风管中的煤粉输送至第一一次风管中。通过在不同的一次风管之间输送煤粉，可以有效减少制粉系统出力对煤粉浓度的制约。
