镇海石化总厂200t/h燃油锅炉过热器管壁温度的测试分析

The Measurement and Analysis ofSuperheater Tube Wall Temperatures of a 200 t/h Oilfired Boiler at Zhenhai Petrochemical Works

本文对两台高压自然循环D型燃油锅炉过热器管壁温度进行了测试,并对辐射型和对流型过热器沿宽度方向热偏差及沿管长的金属温度分布进行了分析比较。

The superheater tube wall temperature of two units of high-pressure natural-circulation D-shaped boilers was measured. An analysis and comparison were performed of the thermal excursion along the width of the superheater and metal temperatures along its tube length for both a radiation type and con-vection type superheater.
