Every country tries to be independent in everything, first of all it is necessary to have a high level of use of own energy resources. Due to the energy crisis, the transition from traditional energy sources to the integrated implementation of alternatives is relevant.
The purpose of the study is complex processing of peat for fuel and extraction of humic substances for fertilizer production.
Studies of extraction of humic substances were performed on a laboratory stand EI-10, which reproduces the work of a pulsating dispersant with an active diaphragm. The classical technology of extraction of humic substances using chemical methods is based on high temperatures of the mixture, which requires high energy consumption. It was proposed mode of extracting humic component developed by the standard rules, but changes in temperature and duration of extraction processing in an alkaline solution cavitation device. The use of cavitation in the technology of obtaining humic preparations makes it possible to achieve their high physiological activity, high yield of water-soluble organic substances. Briquetting was used to increase the energy density of solid fuel.
Based on the research, the technology of obtaining humic fertilizers from peat was developed. The developed technology allows to be integrated into the existing production of the peat briquette plant and will allow to extract as much as possible humic substances from peat with essential reduction of temperature and extraction time with the subsequent application of liquid fraction as fertilizer.
Key words: peat, humates, fertilizers, fuel, extraction
