高温炉内辐射热交换中,炉壁内表面的黑度起着一定的作用,为了提高它的黑度,用高温高辐射涂料(HTR),涂复在高温炉的内壁表面上,以提高炉壁对被加热物的辐射能力,从而增加被加热物所得的热流,提高炉子的热效率,降低能耗。将研制的HTR涂料,用在实验炉上可节能10%左右;在加热炉上的实际使用表明,平均可达3.24—4%节能效果。
In the high-temperature furnace radiant heat exchange, the inner surface of the furnace wall blackness plays a role, in order to improve its blackness, with high temperature and high radiation coating (HTR), coated on the inner wall surface of the furnace to improve the furnace Wall radiation on the object to be heated, thereby increasing the heat flow obtained by the object to be heated to improve the thermal efficiency of the furnace, reducing energy consumption. Will be developed HTR paint, used in the experimental furnace can save about 10%; the actual use on the furnace shows that an average of up to 3.24-4% energy saving effect.
