【摘要】 高温炉窑炉墙内表面,喷涂高辐射节能耐火涂料,炉壁黑度可达0.9以上,西方发达国家可节能10%以上,最高达30%,我国节能也可达5%～10%,电阻炉最高为28%。北京科技大学研制的BJ系列红外高温节能涂料,在冶金企业高温炉窑上应用的效果,分别是:轧钢加热炉节油率5%～7%,停炉降温升至轧制温度的升温时间缩短10 min以上,高炉热风炉送风温度升高10～30℃,吨铁焦比下降2kg以上,工业锅炉平均提高热效率3%～10%,吨汽节煤8～24 kg。使用高辐射节能耐火涂料,是高温炉窑节能降耗,简单易行,投资极小的有效措施之一。更多还原

【Abstract】 After spraying energy saving refractory coating upon the lining surface of high temperature furnace and kiln, the blackness of lining could be more than 0. 9. In advanced countries , 10 %-30 % of energy is saved. In China, 5 %- 10 % of energy also can be saved. For resistance furnace, the effect is the best, the highest saving is about 28 %. BJ series infrared high termperature coating, which has been studied and developed by University of Science and Technology Beijing , have been used in different metallurgical high temperature furnaces. In reheating furnace about 5 %-7 % of oil is saved, after hot stop, the time for raising the temperature to work temperature is reduced by 10 minutes. In hot-blast stove, the temperature of hot blast is increased by about 10 - 30 癈, the coke consumption per tonne iron is reduced by more than 2 kg. In industrial boiler, average thermoeffect is increased by about 3 %-10 % , coal consumption per tonne gas is reduced by 8-24 kg. So use of high radiation energy saving refractory coatings is a simple, easy method with small investment for energy saving and reducing cost for high temperature furnace operation.更多还原
