适合高海拔地区燃气锅炉气体未完全燃烧热损失算法

Gas incomplete combustion heat loss algorithm of gas boiler which is suitable for high altitude

目前气体未完全燃烧热损失q_3的测试方法是根据TSG G0003—2010中的查表法,误差较大。通过研究该海拔地区气体未完全燃烧热损失的影响因素,修正了TSG G0003—2010中的气体未完全燃烧热损失q_3计算公式,并得到适合于高海拔地区气体未完全燃烧热损失q_3的精准计算公式。通过与标准能效测试结果的对比,推导出的公式简单,可以替代目前高海拔地区热工测试q_3的计算方法。

The test method for incomplete combwtion heat loss q3 is based on looking up table in TSG G0003-2010, and the results of the test have a larger error. In this paper, the influencing factors of q 3 are analyzed. The computa-tional model of q3 in TSG G0003-2010 is modified, and the fast formula of q3 is obtained. By comparison with stan-dard energy efficiency test results, it is concluded that this formula calculates simply with higher accuracy. This for-mula can be used to replace calculation method for the q3 in high altitude.
