摘要
30 0MW亚临界锅炉二级过热器喷水减温器的喷雾管 ,由于温度应力引起裂纹 ,改变喷雾管的材质和壁厚 ,达到降低温度应力的效果 。
Because of temperature stress,the spray tube of secondary superheater spray attemperator of 300 MW subcritical boiler may generate crack,the generation of crack can be prevented by change the material nature and wall thickness,and decrease the temperature stress.
