Estimation algorithm for peat as an energy source as a case-study of peat fields in the Leningrad Region

The research significance lies in the creation of an estimation algorithm for energy data of peat depending on its composition, morphology and content of impurities at a specific site or field. As a case-study of the Greko-Ushakovsky and Sakkala peat fields, the estimation method is proposed in the form of the review of the regional power system management, technical analysis of peat samples on a laboratory scale and the comparative analysis of the results and regulatory requirements. The review of the regional power facilities from the cartographic information allows estimating competitiveness of peat as compared with natural gas in application in certain residential areas. The technical analysis is simplified through computational determination of a heat value instead of using a bomb calorimeter. The low heat values are obtained for the Greko-Ushakovsky peat and Sakkala peat: QrL = 10252.1 kJ/kg and QrL = 7897.5 kJ/kg, respectively. The comparison of the technical analysis results and the standard values demonstrates applicability of peat from the test fields in combustion at boiler stations. The proposed method of peat analysis is applicable to peat fields in the regions with lower gas supply, where it is probable to increase the use of peat fuel, for example, the Novgorod Region and the Republic of Karelia.
