Fuel transfer apparatus and boiler facility including same

Abstract

A boiler facility includes first and second fuel transfer apparatuses for transporting fine particulate fuel to a combustor. A first fuel transfer apparatus includes a main body and a diffuser. The main body has a flow space through which fuel is transferred and an inner surface that defines the flow space of the main body and includes a lower inner surface that extends obliquely downward. The diffuser is installed at a downstream end of the main body, the diffuser having a flow space through which fuel is transferred and an inner surface that defines the flow space of the first diffuser and includes a lower inner surface that extends obliquely upward. A second fuel transfer apparatus includes a transfer pipe having a flow channel, a second diffuser installed along the inner circumferential surface of the transfer pipe, and a guide installed in the second diffuser and inclined downward.
