Abstract

See full text

The object is to provide a powder fuel feed apparatus, a gasifier unit, and an integrated gasification combined cycle and a control method of a powder fuel feed apparatus that can suppress deformation of a sintered metal filter with simple and inexpensive configuration. An embodiment includes: a distributor pipe (89) in which a mixed gas containing moisture and a gas in which pulverized coal and nitrogen transported with the pulverized coal are mixed is transported; and a diluting nitrogen system (90) that, when a flow velocity of the mixed gas is less than a predetermined threshold, additionally supplies a diluting nitrogen to a mixing chamber (97) connected to the distributor pipe (89) and forming a part of the distributor pipe (89), and the diluting nitrogen system (90) continuously supplies a predetermined flow rate of the diluting nitrogen to the mixing chamber (97).
