摘要： A high temperature steam valve has a valve casing including a main steam inlet, a main steam outlet and a valve chest. The high temperature steam valve also has a valve seat positioned in the valve chest, a valve element facing the valve seat, and a valve rod slidably penetrating the valve casing to drive the valve element. A cooling steam hole is provided to surround a valve-rod penetrating portion of the valve casing. Cooling steam can be poured into the cooling steam hole from outside through a cooling steam inlet hole and steam having finished heat exchange can be exhausted from a cooling steam outlet hole into the valve chest. The sliding portion between the valve rod provided in the valve-rod penetrating portion of the valve casing and bush is cooled to prevent oxidized scale from depositing on the sliding portion.

摘要： A system and a method for recovery of carbon dioxide in exhaust gas, wherein a liquid absorbent (116) jetted from a liquid absorbent jetting part (101) comes into gas-liquid contact with exhaust gas (114) flowing through a packing (102) from the lower side to the upper side to absorb the carbon dioxide contained in the exhaust gas (114). The flow of the liquid absorbent (116) in a deposition vessel (11) conditioned to a specified pH value is stopped to deposit insoluble compounds as the reaction product of the liquid absorbent (116) against the carbon dioxide, and the carbon dioxide is collected as the insoluble compounds. Thus, the carbon dioxide can be removed from the liquid absorbent which absorbed the carbon dioxide without using steam from a power generating boiler.
