Родовища торфу розповсюджені по всій території нашої пла- нети, однак найбільш інтенсивне накопичення торфу характерне для північної півкулі. У статті наведено аналіз запасів торфу, опи- сано схеми комплексного використання торфу. Детально описано один з найважливіших етапів при виготовленні торф’яних брикетів. Проведено аналіз сушіння торфу, для виготовлення торф’яних бри- кетів. Наведено пропозиції та рекомендації з удосконалення сушін- ня торфу. Описано організацію технологічного процесу видобуван- ня фрезерного торфу.

Title in English

RECOMMENDATIONS FOR IMPROVING PEAT DRYING

English abstract

Peat deposits are spread over the entire territory of our planet, but the most intensive accumulation of peat is characteristic of the northern hemisphere. The article provides an analysis of peat reserves, describes the schemes of integrated peat use. One of the most important stages in the production of peat briquettes is described in detail. Peat drying is a technological process that ensures the removal of moisture from peat by evaporation during extraction and production of peat products. Drying is divided into natural (field) and artificial (in laboratory or factory conditions). Natural (field) drying is accompanied by processes of heat exchange and moisture exchange between the drying peat and the air, inside the peat, between the peat and the soil. Field drying of peat reduces the moisture content of milled peat from 82–75% to 60–50%, finely lumped peat from 82–78% to 45%, lumped peat from 88–86% to 45%. Artificial drying of peat is used in the production of peat briquettes. It is carried out when peat is transported along the drying path of the installation in a mixture with hightemperature combustion gas or superheated steam. The thrust is generated by the fan. Peat ready for briquetting is taken out of the drying unit with a moisture content of 12–18%. The essence of the drying process is that the peat comes into contact with a gaseous environment in which the elasticity of water vapor is lower than that directly above the material to be dried. Under such conditions, moisture, evaporating, passes from the material to this gaseous medium, which is also called a drying agent. That is, the drying agent is a gaseous medium that, under conditions of direct contact and heat exchange with the drying material, perceives moisture that is removed from this material. An analysis of peat drying for the production of peat briquettes was carried out. Proposals and recommendations for improving peat drying are given. The organization of the technological process of obtaining milled peat is described.
