Through the hydraulic researches, it is known however that the real, actual velocities are pulsation velocities into the cross section of the water flow, which are irregularly variable in time and different from the averaged flow velocities. In view of this, in the present work the relations were realized on the basis of the pulsation velocities of the water flows. On this basis, a water erosion approach and method is offered for prediction of the erosive state and stability of the furrows for irrigation.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116132612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A technological analysis for determining losses in percent without implementation of M1 and M2 was made. An investment analysis to determine energy savings in percent and in kWh/y with implementation of M1 and M2 was performed. The value in kWh/y is adjusted with a coefficient of emission factor (CO2) for electrical energy. Further research will involve an analysis of other energy conservation measures and their impact on the reduction of harmful emissions.

The burner uses biogas with the composition 60% - СН4 и 40% - СО2. The basics for modeling are given, as well as the results of modeling. Analysis of the results shows that with an increase in excess air, there is a possibility of reducing the concentration of nitrogen oxides by 58% from the base value at excess air ratio α=1. The conducted numerical study showed that the use of preliminary fuel preparation is one of the most effective ways to reduce the concentration of nitrogen oxides. Pre-mixing reduces local \"rich\" fuel concentrations in the combustion zone, which reduces the formation of high-temperature zones in these areas. As is known, the formation of nitrogen oxides primarily depends on temperature; therefore, the decrease in local high temperatures reduces the concentration of NOx.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131117658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
