前言沸腾床锅炉的燃烧条件与煤粉锅炉大不相同,煤块是在800～900℃左右的沸腾状态下燃烧,由此可以联想,传热管子材料所受到的高温腐蚀也不同于煤粉锅炉。由于沸腾炉的燃烧温度低,不会形成碱性硫酸盐,一般来说,它对环境污染较小。但是,流动介质中的CaO与烟气中的SO_2发生反应生成的CaSO_4(脱硫生成物)等会粘附在传热管子上,产生高温腐蚀,使管材情况恶化,同
Foreword Boiling bed boiler combustion conditions and pulverized coal boiler is very different from the coal block is burning at about 800 ~ 900 ℃ boiling state, which can be associated with the heat pipe material subjected to high temperature corrosion is also different from the pulverized coal boiler . As the boiling temperature of the boiler is low, does not form alkaline sulfate, in general, it is less polluting the environment. However, CaO_4 (desulfurization product) etc. which are produced | generated by CaO in a flowing medium and SO_2 in a flue gas adhere to a heat transfer pipe | tube, and a high temperature corrosion generate | occur | produces and the pipe condition worsens.
