The article presents a new approach to forecasting the composition of producer gas. Thermochemical treatment of biomass as an effective method of producing flammable gas was presented. The methods of predicting the gas composition of the generator are described, and then its efficiency depending on the parameters of the device. In order to create a method for forecasting gas composition, the authors' works were used as the basis, in which the energy characteristics of the gases obtained were assessed. It was assumed in this paper that it is very important to understand the influence of each parameter on the energy characteristics of the gas. This made it possible to optimize the composition and predict thermal characteristics. In this article, we present the results of experimental studies on biomass gasification and a mathematical model based on Gibbs free energy.

The article presents the results of research related to the use of ash from thermal power plants for the production of porous heat insulating materials. Using the method of differential - thermal analysis, the optimal values of the composition of the raw mix and the thermal regimes of the formation of the porous structure were found. It is shown that it is possible to obtain a new ash-based binder and thus replace up to 70% of cement in the production of thermal insulationthe properties of the new material are similar to the properties of foam concrete.

The article presents data on changes in physical and chemical properties of mixtures of generator gases with natural gas and the issue of the optimal ratio of these gases in the mixture. The results of research on the basic properties of flammable mixture of generator gases and natural gas are presented, on the basis of which the optimal composition of the mixture was proposed.

The article presents the results of experimental studies of the process of biomass heat treatment. The method of mathematical modeling of the biomass gasification process is improved on the basis of the thermodynamic model of Gibbs free energy minimization In most countries, their energy strategies involve an increase in the share of renewable energy sources, including using a sufficiently large biomass potential. The solution of the Lagrangian function made it possible to determine the composition of the generator gas and the efficiency of the process. The accuracy of the proposed mathematical is estimated. The obtained results of the work can be used to determine the optimal conditions for gasification in the development of biomass gasification technologies.
