Abstract: An atomizer for slurry fuel which provides improved assembly thereof and improves the atomization of fuel and provides improved wear resistance. The atomizer for slurry fuel comprises an intermediate member, a slurry fuel passage and a gas passage respectively integrally formed of ceramic, and a mixing chamber being provided at the upstream side of a fuel jet port for mixing slurry fuel with gas, the intermediate member being fixed to a fuel supply body by a cap together with a steam cap and a fixed ring formed of ceramic, respectively and a set bolt fixing a target formed of ceramic to the intermediate member by penetrating a target support member and being retained to a strut wall by a lock nut.
