炉子热效率的测试计算是能源装置研究最重要的计算之一。热效率的高低直接反映炉子性能好坏。因此准确测得炉子的热效率足十分必要的。目前一般炉子采用直接法,即正平衡法进行测试。它的定义为: 热效率η=能量传给加热物质速率/燃料给入率×燃料热值×100% 为了验证直接法测试的结果,可采用热损失法,也称反平衡法来验证。这种方法是通过测试或估算热量损失来获得结果的。它的定义是: 热效率E=100%一∑各项热损失-100%-(L_(Re)+L_(FA)+L_(SA)+L′_(FA)+L′_(SA)
Test calculation of furnace thermal efficiency is one of the most important calculations for energy plant research. The level of thermal efficiency directly reflects the good or bad furnace performance. Therefore, accurate measurement of the thermal efficiency of the stove is very necessary. The current general furnace using direct method, that is, the method of positive balance test. It is defined as: thermal efficiency η = energy transferred to the heating material rate / fuel input rate × fuel heat value × 100% In order to verify the results of the direct method test, heat loss method, also known as anti-balance method to verify. This method is achieved by testing or estimating heat loss. It is defined as: thermal efficiency E = 100% a Σ the heat loss -100% - (L_ (Re) + L_ (FA) + L_ (SA) + L ’_ (FA) + L’ _
