我国工业炉普遍存在着工艺陈旧,筑炉材料落后,能源利用率低的现象.为了有效利用能源和节约能源,必须采用先进炉衬与技术改造. 一、工业窑炉的节能措施工业窑炉一般都是以煤、油、电作为热源,使被加热物体温度升高.但是热源所放出的热量,仅有一部分被吸收,其余都白白浪费了.热源与被加热物体之间的热交换有三种形式,即热传导、热对流、热辐射.对于工业窑炉来讲,热传导是损失热能的主要方面,而热对流、热辐射中的一部分热量可以被加热物体吸收.因此,如何减少热传导散失的热量,增加热对流、
Industrial furnaces in our country are generally obsolete, with outdated materials and low energy efficiency. In order to make efficient use of energy and save energy, advanced linings and technological innovations must be adopted. 1. Energy-saving measures for industrial kilns Industrial kilns are generally Is based on coal, oil, electricity as a heat source, so that the temperature of the heated object, but the heat released by the heat, only part of the absorption, the rest are wasted.Heat heat and heat exchange between objects in three forms , That is, heat conduction, convection, heat radiation.For industrial kilns, heat conduction is the main aspect of loss of heat energy, and heat convection, heat radiation can be part of the heat absorbed by the heating object.Therefore, how to reduce the heat conduction heat loss, Increase heat convection,
