かしながら、このような材料を使用しても依然と
して、その寿命は短かい。 In a cyclone used as a heat exchanger for firing powder or granular materials such as cement, an exhaust duct is provided to penetrate the cyclone ceiling and protrude inside the cyclone in order to increase collection efficiency. However, this inner cylinder part is easily deformed because it is exposed to high temperature gas.
There is also a risk of wear due to powder and granules and corrosion due to high temperature gas. Therefore, the inner cylinder portion is required to be made of a metal material with high heat resistance and corrosion resistance, such as heat-resistant cast steel. However, even with the use of such materials, their lifetimes are still short.

とにより、捕集効率の低下を防ぎながら、内筒を
無くすることに成功した。 As a result of intensive research, the inventors succeeded in eliminating the inner cylinder while preventing a decrease in collection efficiency by arranging a rectifier plate of an appropriate size in an appropriate state within the cyclone.
