【 摘 要 】

The paper describes some ways of greening the agricultural energy industry, in particular, methods of utilizing industrial waste to produce fuel briquettes using pig manure as a binder and creating a biogas plant in the climatic conditions of Siberia, which allows organic waste (manure, bird droppings, household waste) to be recycled etc. The optimal ratios of the initial components in the briquette mixture are revealed. It is established that the best compositions, taking into account the strength of the briquettes obtained, are briquettes with coal of grade D - up to 10%: grade B2 - from 60%: manure with moisture content 72% - not more than 30%. It was determined that reducing the proportion of binder (manure) to 15% leads to the need to increase the pressure of the press to 300 kgf / cm2. Adding manure in the briquette changes the burning characteristics, the briquette burns longer, and it becomes possible to reduce the pressure. The data on the kinetics of drying the prepared briquettes with the determination of the optimal mode providing explosion-fire safety and the absence of volatile substances were obtained. The possibility of introducing biogas technologies into the agricultural sector of the Krasnoyarsk Territory economy has been considered.
