Economic and statistical methods of frequency maintenance of biogas plants

Abstract

The article gives the importance of the technical operation of biogas plants and methods for their determination in the development of alternative energy sources from organic waste. When comparing the two methods in experiments: determining the frequency of maintenance by the acceptable level of reliability and the acceptable value and regularity of changes in the parameter of the technical condition of biogas plants. Their advantage is shown: in simplicity and the possibility of taking into account risk and taking into account the actual technical conditions of biogas plants (diagnostics), in the ability to guarantee a given level of reliability in taking into account variations in the technical condition. Also, the disadvantages of these methods are given, such as the impossibility of making full use of the resource of individual parts of a biogas plant, due to the fact that the frequency of maintenance (П0) is significantly less than the acceptable level of failure-free operation (ñ), in the absence of direct economic assessments of the consequences of biogas plant failures and the lack of direct consideration of economic factors and consequences. The need to receive (or have) information on the patterns of changes in the parameters of the technical condition. In connection with these, the article presents the results obtained by the method of economics and statistics, while it is shown that the technical and economic method is applicable to complex and expensive systems of units and assemblies that do not directly affect the safety of the biogas complex.
