모석화기업4호기륜궤조（국산C12-3．43/0．981형조정추기식기륜궤）재계동과정중배기항존재로측여전측수평방향온차대적현상，통과이론분석화유한원모의，탐명료차현상적궤리，급출료소제계동과정배기항수평방향대온차현상적조시。
In the startup process of the No .4 steam turbine unit ( domestic C12 -3.43/0.981 adjustment extraction turbine ) in a petrochemical industry enterprise ,a large temperature difference was found in the horizontal direction between the furnace side and generator side of the exhaust hood .The mechanism of this phenomenon was ascertained by theoretical analysis and finite element simulation , and the measures were given to eliminate the large temperature difference in the horizontal direction during starting process .
