Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a porous refractory for flue obturation prevention capable of preventing a flue from being obturated by eliminating the adhesion and stacking of a flying molten ash. SOLUTION: This porous refractory for flue obturation prevention for preventing the flue from being obturated by the adhesion of the flying molten ash contained in an exhaust gas by jetting a gas into the flue 1 comprises an apparent porous ratio of 25 to 32.5%, a porous volume of pores with a diameter of 10 to 100 μm of 70 to 90%, and a permeability of 6.78×10-5to 3.39×10-3cm2/sec atm.
