Abstract

Within the work, carried out in the Republic of Belarus on the implementation of the state program "Peat", physico-mathematical model of the raw mixture agglomeration using local fuels was developed, the directions necessary to implement the plan of increasing the peat use for energy purposes were identified. Physico-mechanical properties of raw materials and fuel briquettes, the elemental composition of the peat, the main technical parameters of the peat crusher were presented. Fractional composition of fuel based on fuel briquettes after the first and second crushing was determined. The mathematical models for determining the hydraulic conductivity coefficient were developed, and the influence of different contents of loam, fragmented peat and coal in a mixture on the aggloporite strength was determined. The dependences of aggloporite strength on its density when adding crushed briquettes and sawdust in the obtained experimental batch were defined. Application of the above techniques has allowed to get the economic effect at the MCMP of more than 100 million BYR (approx. 10 000 USD) at the release of the experimental batch of aggloporite.
