The present paper involves applicative research in the field of biogas production with the accent on small laboratory scale installations built for biogas production, preliminary testing of substrate for biogas production and combustion applications for biogas-like mixtures. The interconnected aspect of the presented material involves cumulative expertise in multidisciplinary fields of interest and continuous development of possibilities to determine the energetic potential of substrates subjected to biodegradable fermentation conversion for further applications. The research analyzed the combustion behavior of biogas with different methane/carbon dioxide ratio without and in the presence of specific catalysts. Also, laboratory analysis on biomass substrates for determining their physical and chemical potential for different applications was performed. The main conclusions are drawn revolve around the untapped potential of the different types of biomasses that are not commonly used in the production of renewable energy carriers, like biogas, and also the potential use of residual biomass in combustion processes for an enclosed life cycle from cradle to the grave. The study involving the use of catalysts in biogas combustion processes present possible solutions which can be developed and implemented for increasing the combustion quality by using relatively cost-effective materials for the production of catalytic materials.

It is common knowledge that theoretical approaches do not allow conducting the objective assessment of the reliability and efficiency of the boiler equipment operation, hence, application of numerical approaches is introduced in the paper. There is the urgent need to assess reliability and efficient operation of boilers at the design stage. The analysis of the temperature level, gas dynamics in the combustion chamber of the boiler and the conclusion about the reliability and efficiency of the designed boiler operation are based on the numerical research.

The experimental data on the basis of which, there was studied the effect of various factors on the combustion temperature water-oil emulsion in the boiler units. By the method of experiment planning there was obtained mathematical model of the influence of these factors: the temperature of the emulsion, the water content in the emulsion viscosity, excess air ratio in the combustion temperature, which can be used to predict the operating parameters of the combustion process.
