本文介绍了一种植物油混合物在低压辅助气流粉碎燃烧器（O型乳化燃烧器）中的燃烧结果。该混合物由大豆和向日葵精炼植物油（54.4%）和向日葵和油菜籽粗植物油（45.4%）制备。研究了燃料流量、二次风流量以及燃料预热温度对燃烧、性能和污染物排放的影响。此外，还将从这种植物油混合物中获得的燃烧结果与以前纯植物油燃烧中获得的燃烧结果进行了比较。对于所有测试条件，植物油混合物燃烧性能超过77%，并且NOx排放极低（<60 ppm）。在确定的最佳操作条件下：未预热的植物油和中间气流速率，CO排放几乎可以忽略不计（5 - 17 ppm），无论使用的燃料流量。植物油混合物的污染物排放和燃烧性能与精炼大豆油、葵花籽油和菜籽油燃烧时获得的污染物排放和燃烧性能相当，这些油都含有高比例的不饱和脂肪酸（主要是油酸和亚油酸）。
This work presents the combustion results of a vegetable oils blend in a low-pressure auxiliary air fluid pulverisation burner (o emulsion burner). This blend was prepared from soy and sunflower refined vegetable oils (54.4%) and sunflower and rapeseed crude vegetable oils (45.4%). The influence of varying the fuel flow rate, the secondary airflow rate as well as the fuel preheating temperature on combustion, performance and pollutant emissions was studied. Additionally, a comparison between the combustion results obtained from this mixture of vegetable oils and those previously obtained in combustion for pure vegetable oils was also carried out. For all of the conditions tested, the vegetable oil mixture combustion performance exceeded 77% and NOx emissions were extremely low (<60 ppm). In the established optimal operating conditions: un-preheated vegetable oil and Amid airflow rate, CO emissions were virtually negligible (5–17 ppm), regardless of the fuel flow used. The pollutant emissions and the combustion performance of the vegetable oils blend are comparable to those obtained in the combustion of refined soybean, sunflower and rapeseed oils, all of them with a high percentage of unsaturated fatty acids (mainly oleic and linoleic).
