Cyclone, gasification furnace, integrated gasification combined cycle facility, and method for manufacturing cyclone

摘要

PROBLEM TO BE SOLVED: To provide a cyclone having a long life, which can prevent a decrease in the efficiency of the cyclone. SOLUTION: A cyclone 161 includes a cyclone main body 162 in which a product gas generated when a carbon-containing solid fuel containing carbon is gasified is guided inside to centrifuge particles in the product gas from the product gas. The outer peripheral surface of the cyclone main body 162 opposite to the inner peripheral surface of the cyclone main body 162 in the rotation direction of the generated gas including the position of the inlet portion 163 that guides the generated gas inside the cyclone main body 162 and the position of the generated gas introduced from the inlet portion 163. The backing plate 167 provided in the above is provided. [Selection diagram] Fig. 3
