聚能环对燃气灶性能的影响OA

Atmospheric gas range paired with energy gathering rings having typical structures in the market are selected to test the heat load,CO volume fraction in dry flue gas with excess air coefficient of 1(referred to as characteristic CO volume fraction)and thermal efficiency of the gas range paired with energy gathering rings,and analyze the influence of energy gathering rings on the technical parameters of the gas range.When using gas range paired with an original energy gathering rings,the measured converted heat load and characteristic CO volume fraction meet the standard requirements,while effectively improving the thermal efficiency.Three technical parameters of meas-ured converted heat load,characteristic CO volume fraction and thermal efficiency are investigated,and the self-matching energy gathering ring tested cannot a-chieve all three technical parameters that meet the standard requirements.If it is necessary to improve the thermal efficiency of gas range,the original energy gathering rings of gas range should be used,and self-matching energy gathering rings should not be used.
