Abstract

Energy is regarded as one of the most crucial resources in the industrial process. Numerous measurements were made in the year 2021 in the workshops of the Agricultural Engineering Department, Faculty of Agriculture, Ain Shams University, Egypt, using a gasoline engine (single cylinder with air-cooling) that was used to power an irrigation pump with a discharge diameter of 2 inches, which was manufactured in Egypt. To combine natural gas and air before entering the engine, a variety of mixers were created. Four different types of mixers were employed with iron pipes of various sizes: 90° angle T-mixer (T90), 45° angle T-mixer (T45), 30° angle T-mixer (T30), and venture mixer (VM). The engine shift speeds were set at 1,750, 2,300, 2,900, and 3,500 rpm. The water pump was powered by natural gas and gasoline. The findings in this study focused on the evaluation of technical indicators for several types of mixers that combine natural gas and air to power an irrigation pump, where the actual power (braking power) is superior to all types while operating with gasoline (3.07 kW). A commensurability on every side the report of on the up steam, in the mixer type (T45) (2.83 kW) was 7.8% about than gasoline. The lowest specific fuel consumption (S.fc) for gasoline was 219.025 gm/Kw.h at an engine speed of 2,900 rpm. The T45 mixer had the lowest S.fc of 234.612 gm/KW.h, compared with other types of mixers at an engine speed of 2,900 rpm, an increase of 6.6% compared with gasoline. The T45 mixer had the highest pump discharge of 528.133 L/min, an increase of 2.1% compared with gasoline. Compared with other types of T-mixers, the T45 mixer had the highest actual hydraulic power of 0.6 kW, which was 10.5% lower than that of gasoline. As for the economic indicators, the T90 mixer had the lowest net present value (NPV) of 77219.5, and the T45 mixer had the highest NPV of 106900.7. The mixer-type VM had the lowest benefit–cost ratio (B/C) of 1.38, and the T45mixer had the highest B/C of 1.54.

用T型天然气混合器对发动机和灌溉泵的技术经济评价

能源被认为是工业过程中最重要的资源之一。2021年，在埃及艾因沙姆斯大学农业学院农业工程系的车间里，使用一台汽油发动机（单缸风冷）进行了大量测量，该发动机用于为埃及制造的排水直径为2英寸的灌溉泵提供动力。为了在进入发动机之前将天然气和空气混合，我们制作了各种混合器。采用了四种不同类型的搅拌器和不同尺寸的铁管：90°角T形搅拌器（T90）、45°角T型搅拌器（T45）、30°角T式搅拌器（T30）和venture搅拌器（VM）。发动机换档速度设置为1750、2300、2900和3500转/分。水泵由天然气和汽油提供动力。本研究的结果集中在对几种类型的混合器的技术指标的评估上，这些混合器将天然气和空气结合起来为灌溉泵提供动力，在使用汽油（3.07kW）的情况下，实际功率（制动功率）优于所有类型。在混合器类型（T45）（2.83kW）中，每侧的上蒸汽的可公度约为汽油的7.8%。发动机转速为2900转/分时，汽油的最低比燃料消耗量（S.fc）为219.025克/千瓦时。在发动机转速为2900转/分时，与其他类型的混合器相比，T45混合器的S.fc最低，为234.612克/千瓦时，与汽油相比增加了6.6%。T45混合机的泵流量最高，为528.133L/min，与汽油相比增加了2.1%。与其他类型的T型搅拌机相比，T45搅拌机的实际液压功率最高，为0.6 kW，比汽油低10.5%。就经济指标而言，T90搅拌机的净现值（NPV）最低，为77219.5，T45搅拌机的NPV最高，为106900.7。VM型搅拌机的效益成本比（B/C）最低，为1.38，T45型搅拌机的B/C最高，为1.54。
