摘要： PROBLEM TO BE SOLVED: To reduce the damage to the protective tube of vapor piping of a vapor temperature reducing device and improve the reliability of the vapor temperature reducing device.
SOLUTION: In the structure having a conventional protective tube 1 with an integral structure, one part of the protective tube 1 is cooled by spray water 5 to greatly contract, so that the protective tube is apt to be greatly bent. However, even when there is a temperature difference between the upper tube 1a and the lower tube 1b of the protective tube 1 made of two parts and provided in the vapor piping 2, the tubes can respectively slide in the longitudinal directions in the vapor piping 2. A differential expansion due to thermal contraction of the two parts (the upper tube 1a and the lower tube 1b) forming the protective tube 1 is absorbed by atomizing the spray water 5 from a spray nozzle 3a. Consequently, bending stress generated in the protective tube 1 is greatly decreased.

摘要翻译：要解决的问题：减少对蒸汽降温装置的蒸气管道保护管的损害，提高蒸气降温装置的可靠性。解决方案：在具有一体结构的传统保护管1的结构中，保护管1的一部分被喷射水5冷却，从而大大收缩，使得保护管容易弯曲。然而，即使在蒸气管2中设置有由两部分构成的保护管1的上管1a和下管1b之间存在温差，管也可以分别在蒸气管2内沿长度方向滑动形成保护管1的两部分（上管1a和下管1b）由于热收缩而产生的不均匀膨胀被喷雾器3a雾化，从而被吸收。因此，保护管1中产生的弯曲应力大大降低。

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for preparing a desulfurizing agent with a good absorbing performance of sulfur oxides in an exhaust gas and a dry exhaust gas desulfrization method using the obtained desfulfurizing agent. SOLUTION: In the method for preparing the desulfurizing agent, after a silicon-feeding substance is mixed into one kind or more of oxides of an alkaline earth metal, water is added to the mixture. The oxide and the silicon-feeding substance are reacted by a heat of hydration when the oxide of the alkaline earth metal is hydrated. Thereby, an excess amount of moisture content is evaporated to make a powder.
