220t/h电站燃油炉改烧水煤浆炉内传热及排放特性的试验

Heat Transfer and Emission Characteristics Tests of a 220 t/h Oil fired Utility Boiler Retrofitted for Firing Coal water Slurry

水煤浆是一种新型的代油洁净燃料。文中介绍了电站燃油锅炉改烧水煤浆后炉内传热及其污染物的排放测试结果,包括温度场、火焰黑度、过热器管壁温度、排烟温度、排烟成分的测量。这些数据表明了燃烧水煤浆的一些特点,可为锅炉改烧水煤浆的改造和设计提供参考。

Heat transfer performance and pollutant emissions were measured and tested for an oil-fired 220 t/h utility boiler being retrofitted to fire coal-water slurry, a new type of clean fuel as a replacement for oil. Measurements were taken of the temperature field, flame emissivity, superheater tube wall temperature, exhaust gas temperature and composition. These data represent some special features of coal-water slurry combustion and may serve as reference data during the design and retrofitting of a boiler for firing coal-water slurry.
