PURPOSE:To increase the durability and facilitate the maintenance by a structure wherein macromolecular material such as heat resisting, acid resisting and elastic rubber or the like is lined over the internal surface of the smokestack, flue and the like. CONSTITUTION:The acid resisting and water-impermeable rubber 8 is lined over the inner wall parts, which contact with the exhaust gas, of the smokestack 3, the flue 4 and the like. As for the lining method of the rubber 8, there are two types: one type is to fit sheet-like rubber along the inner wall parts and the other type is to coat liquid rubber with suitable viscosity by spraying. In such a manner as described above, the work process is simplified, resulting in reducing the material cost and as well as the working cost to low level. |
