For countries with significant reserves of peat is an important issue of energy-efficient production of peat briquettes. The article states about the necessity of determining the optimal equipment’s operation regimes of peat briquettes production. This especially due to the plants with a pneumatic steam-water peat dryer. These dryers are characterized by high productivity and low peat losses compared to factories with other types of dryers. This is achieved by the fact that the drying agent is used in a closed circuit and the heat of low-potential vapor is used. However, the drying process in this dryer has high energy consumption. That is why finding ways to reduce electricity consumption is a key task for implementing these dryers in production. The data and technology of operation the pneumatic steam-water dryer for creating a factor field of process was analyzed in article. In this paper, the basic parameters of peat that affect the peat drying regime, parameters of peat that are changed during the drying process and the parameters of the drying peat quality are determined. There were highlighted the disturbance effects and initial parameters of the model of peat drying process from them. The main controllable and uncontrollable effects and output parameters of the drying process also were chosen. Based on the analysis of the factors of the peat drying process and the developed functional model for the energy technology of the peat drying process, it was determined the interrelations of the output parameters from the input disturbances and control influences It was revealed that the main output parameter of the model is the parameter of electric consumption. The value of this parameter for the certain operating regimes should be minimized with the observance of qualitative indicators of the dried peat and the level of heat consumption by determining the necessary values of control effects.
