Disclosed herein is a coal fed power generation system comprising a mill in fluid communication with a furnace; where the mill is operative to pulverize coal and to ventilate the coal; where the furnace contains more than one burner or burner nozzles; where the burner or burner nozzles are operative to receive the coal from the mill and combust it in the furnace; and a plurality of flow control devices; where at least one flow control device is in fluid communication with the mill and with the burner or burner nozzle; and where the flow control device that is in fluid communication with the mill and with the burners or burner nozzles is closed to prevent fluid communication between the mill and the furnace during the operation of the furnace.

Provided is a solid fuel pulverizing device (100) provided with: a ventilation unit (30) configured to ventilate an interior of a housing (11) with primary air for supplying a solid fuel pulverized by a roller (13) to a classifier (16); a pressure detector (50) configured to detect an internal pressure of the housing (11) relative to a reference pressure; a flow rate detector (60) configured to detect a flow rate of the primary air blown into the interior of the housing (11) by the ventilation unit (30); and a controller (40) configured to perform control and transition the solid fuel pulverizing device (100) to a stopped state upon the internal pressure detected by the pressure detector (50) being a predetermined pressure or higher and the flow rate of the primary air detected by the flow rate detector (60) being a predetermined flow rate or less.

This solid fuel burner is provided with: a venturi tube in which a channel for mixed fluid in a fuel nozzle narrows toward the center in the channel cross section; a fuel concentrator that imparts, to the mixed fluid, a velocity component away from the center of the fuel nozzle; and a channel separation member that separates the channel of the fuel nozzle into an internal side and an external side; wherein the channel separation member is shaped in such a way that the cross sectional area of an external channel is larger at the downstream end than at the upstream end, and the upstream end of the fuel concentrator is located between the upstream end and the downstream end of an expanded portion of the venturi tube. This solid fuel burner prevents solid fuel particles, which is ground biomass fuel, from adhering and depositing inside the nozzle.

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.
