Description
Summary:The main types of molded solid fuel from peat are sod peat and peat briquettes. Sod peat is produced in fields using solar energy for drying, while peat briquettes are produced in factories using artificial drying. The spontaneous process of structure formation in sod peat is energetically advantageous. It is based on shrinkage deformations during drying, leading to a reduction in the size of peat samples. At the same time, intermolecular interactions are intensified to form hydrogen bonds between the structural elements. In the peat briquettes, the intermolecular interaction is provided at the expense of the initial energy input for the pressing of crushed peat. Thepaper discusses main theories of structure formation, which help to explain the complex physical and chemical mechanism of these processes, the role of micro- and macrostructure, energy approach, the impact of the density of the structure of peat systems and a comprehensive assessment of the influence of mineral components. The authors propose recommendations on the application of these theories in the control of structure formation in peat and sapropel systems and their compositions with mineral components.
