摘要:

随着燃气热泵的大力推广,有关燃气热泵排放的标准愈发严格。通过燃气热泵烟气排放试验,研究在燃气热泵稳定运行工况下,燃气消耗量、过量空气系数、发动机转速对燃气热泵烟气排放的影响。结果表明:w(NOx)和烟气温度整体随燃气消耗量的增加呈上升趋势,提升过量空气系数可以降低w(NOx),并使w(CO)维持在较低水平。从降低污染物排放的角度来说,过量空气系数宜维持在1.40左右。随着发动机转速的增加,w(NOx)和w(CO)都呈先降后升的趋势,最小值均出现在转速为1 250 r/min左右时,而且烟气温度与发动机转速呈线性正相关。

Abstract:

With the popularization of gas engine-driven heat pumps, their emission standards are becoming more and more strict. Thus, the influences of gas consumption, excess air coefficient and engine speed on the flue gas emissions from gas engine-driven heat pumps under steady operation condition are studied in a flue gas emission experiment. The results show that the w(NOx)and flue gas temperature show upward trends with the increase of natural gas consumption, while increasing excess air coefficient can reduce the w(NOx)and keep the w(CO)at a low level. From the point of view of reducing pollutant emissions, the excess air coefficient should be kept at around 1.40. With the increase of engine speed, both w(NOx) and w(CO) decrease at first and then increase with their minimum values occurring at a speed of 1 250 r/min or so, and the flue gas temperature shows a positive linear relationship with the engine speed.

Key words: gas engine-driven heat pump, flue gas emission, gas consumption, excess air coefficient, engine speed, emission reduction
