在工业炉窑节能工作中,“热平衡”是重要的基础工作。首先对炉窑的各能量(主要是热量)收入与支出项目进行测定,再基于能量守恒定律通过计算列出热平衡表,使热量收支各项之和相等。这样一方面便于对各项热量的使用合理性进行分析研究;另一方面也为计算热能利用技术指标提供数据。 In the industrial furnace energy conservation work, “heat balance” is an important basic work. Firstly, the income and expenditure items of each energy (mainly heat) in the kiln are measured, and then the heat balance sheet is calculated and calculated based on the law of conservation of energy so as to make the sum of all the heat revenues and expenditures equal. On the one hand, it is easy to analyze and study the rationality of each heat consumption; on the other hand, it also provides data for calculating technical indicators of thermal energy utilization.
