PURPOSE:To obtain a nozzle for removing deposited dust by blowing off efficiently said dust with a compressed gas by providing plural gas-ejecting holes which face obliquely outward against an axial center. CONSTITUTION:Above a catalytic block having many vertical independent passages, a nozzle 2 is faced obliquely from upper place to a constituted single plate of the block. The end of the nozzle 2 is blocked by a blocking wall 15, and four gas ejecting holes faced obliquely outward against the axial center are provided at the places close to the end of the peripheral wall. The material of the nozzle 2 is desired to be excellent in heat resistance and corrosion resistance. Since the nozzle 2 has plural gas ejecting holes 17 facing obliquely outward against the axial center, a compressed gas is ejected obliquely on the deposited dust and the dust can be removed efficiently. |
