EXPERIMENTAL STUDY ON COAL FEEDING PROPERTY OF 600MW CFB BOILER
In the CFB boiler technology, improving the steam parameters can lead to the improvement of power plant efficiency. However, during the process of large scale, there exist some key problems，such as uniformity of coal feeding, it is a major factor which showed great influence on the boiler efficiency, temperature distribution, etc. In the paper, based on the structure of commercial 600MW CFB boiler unit and similarity principle, the experiment-rig was set-up; using hot trace particle injection and thermocouple temperature collection system, the three-dimensional diffusing property of hot trace particle was analyzed by measuring the temperature distribution at different positions under different operating conditions of variant bed material height and fluidized air velocity.
