河南科技HenanScienceandTechnology机械与动力工程总第802期第8期2023年4月燃天然气非冷凝锅炉排烟热损失简化及应用朱荣全李勇（河南省锅炉压力容器检验技术科学研究院，河南郑州450000）摘要：【目的目的】简化燃天然气非冷凝锅炉排烟热损失的测试。【方法方法】以使用西气东输天然气燃料的非冷凝锅炉为研究对象，进行技术资料搜集，并结合目前非冷凝天然气锅炉能效测试报告计算方法。【结果结果】总结出一种适合河南省区域内非冷凝天然气锅炉排烟热损失测试方法，并结合实际测试过程对该方法进行验证。【结论结论】采用简化后的测试方法得出的数据与详细测试的原始数据进行对比，两者排烟热损失之差为+0.04%，只需测量排烟温度、入炉冷空气温度、烟气中的氧含量，测量项目少，降低测试成本，提高测试准确度，便于在实际工作中的应用。关键词：天然气锅炉；热效率测试；非冷凝锅炉；排烟热损失中图分类号：TK31文献标志码：A文章编号：1003-5168（2023）08-0039-06DOI：10.19968/j.cnki.hnkj.1003-5168.2023.08.008SimplificationandApplicationofHeatLossofExhaustGasfromNaturalGasFiredNon-CondensableBoilerZHURongquanLIYong(TheBoiler&PressureVesselInspectionT&SInstituteofHenanProvince,Zhengzhou450000,China)Abstract:[Purpose]Tosimplifythetestofheatlossofexhaustgasofnon-condensablenaturalgasfiredboiler.[Methods]Thispapertakesthenon-condensableboilerusingnaturalgasfuelfromtheWest-EastGasPipelineastheobject,collectsthetechnicaldata,andcombinesthecurrentcalculationmethodofnon-condensablenaturalgasboilerenergyefficiencytestreport.[Findings]Atestmethodforheatlossofexhaustgasfromnon-condensablenaturalgasboilerinHenanProvincewassumma⁃rizedandverifiedwiththeactualtestprocess.[Conclusions]Comparedwiththeoriginaldataofthede⁃tailedtest,thedifferenceofheatlossofexhaustgasmeasuredbythesimplifiedtestmethodis+0.04%,andinthiswayonlythetemperatureofexhaustgas,thetemperatureofcoldairenteringthefurnace,andtheoxygencontentinthefluegasareneededtobemeasured.Itisconvenienttoapplyinpracticalworksincethismethodthathaslessitemstobetestedcanreducecostsandimprovethetestaccuracy.Keywords:naturalgasboiler;thermalefficiencytest;non-condensingboiler;exhaustgasheatloss0引言...
