PURPOSE: A precast chimney is provided to improve workability and safety without using a welding method and to collect and recycle waste heat from high temperature combustion gas emitted through the chimney. CONSTITUTION: A precast chimney (100) is a cylindrical-shaped chimney, which discharges combustion gas to the outside. The precast chimney includes the mixture of cement, plaster and styrofoam granules. The precast chimney comprises multiple precast chimney members which are divided along a circumferential direction with the same interval. |
