Evaluation of one year of operation of the biogas plant in Suchohrdly u Miroslavi

Abstract

The manner of designing biogas plants is eagerly described by each and every seller or supplier of the respective technology. Numerous feasibility studies comprising forecasts of future operation featuring different quality levels have been written. However, it is rarely possible to obtain information comparing the anticipated future numbers and real values. Nevertheless, an evaluation of past operation of BGP is of utmost importance for calibration of the calculation methods used for designing of future BGPs. Information obtained on the basis of an evaluation is also useful for the purpose of verification of correct functionality of the equipment as well as optimisation of its operation with the objective of achieving the planned (or even better) values of profitability of each respective project. A comprehensive analysis of a biogas plant is a project sensitive to accuracy of inputs. Measurements of amounts and quality of the feed substrate throughout the whole year, which comprises numerous criteria, is highly demanding and complicated, and therefore the objective of this evaluation is to analyze the performance, production and consumption of the biogas plant in the course of a calendar year (Schulz et al., 2004). Power measuring tasks are performed using calibrated gauges (which are mostly used for invoicing purposes), thus ensuring accuracy and credibility of the input data.
