Abstract
This paper is devoted to the study on the production of fuel briquettes from vegetable raw materials. It describes the current state of this market segment in Russia, European countries and the USA, and studies on the reasons for a significant demand for this type of fuel. Based on the presented analysis, it was found that fuel briquettes surpassed traditional wood in such qualitative indicators as calorific value, burning time, density, and were also characterized by a significantly lower moisture content and volatiles. They are an environmentally safe type of fuel, contributing to solving the problem of waste disposal of woodworking and agricultural enterprises. The authors determined types of vegetable raw materials used for the production of fuel briquettes and carried out a comparative analysis of the main technological indicators of fuel briquettes produced from various natural materials. The paper describes a production process of briquetted raw materials. The authors studied main pressing methods: hydraulic, mechanical stamping and screw ones, and determined how a pressing method influenced the quality of finished products. It is noted that bri-quettes produced by hydraulic and mechanical stamping methods are characterized by low physical and mechanical parameters, which significantly limit their storage time and the range of transportation. These circumstances determine their low cost and low demand for these products. It is shown that the most feasible method is screw pressing, which makes it possible to produce high-quality fuel briquettes resistant to mechanical impacts, transportation and long-term storage. The study on the technological aspects of the production of fuel briquettes showed that the high quality of this type of product was achieved by heating, promoting the release of lignin, acting as an intercellular binder and ultimately leading to an increase in the physical and mechanical parameters and, as a result, to a significant expansion of their scope of application.
