On the issue of reducing greenhouse gas emissions from the combustion of organic fuels

Relevance. Russia has ratified the Paris Climate Agreement. However, European legislation is ambiguously aimed at extracting its own benefits in the current international relations, especially during the period of sanctions against Russia. Expectation of introduction of a carbon tax on the products and services of industry organizations requires a comprehensive analysis of the situation in the field of technology and technologies that contribute to reducing greenhouse gas emissions. Aim. Study of approaches and technologies aimed at reducing greenhouse gas emissions that stimulate the environmentally friendly production of thermal and electrical energy; identification of promising and affordable greenhouse gas condensation technology for domestic energy and features of its application. Object. The list of greenhouse gases was established by the Kyoto Protocol in 1996. The main of greenhouse gases for the energy sector are emissions of carbon dioxide generated by burning fuel in generating heat and electricity. Methods. Analysis of literature data on technologies for utilization of greenhouse gases, the possibilities of its use and reduction of emissions. Analytical calculations were performed to assess the effectiveness of carbon dioxide condensation technology. Results. The authors have carried out the analysis of literature data on regulatory requirements, UN recommendations and aspects of greenhouse gas utilization. They established a promising and affordable technology of greenhouse gas condensation in order to capture and absorb carbon dioxide during fuel combustion when producing thermal and electrical energy. The paper introduces the economic assessment of the costs of purchasing sorbents and the possibility of their extraction and conclusions on the utopian of the tasks of the Paris Climate Agreement

Aerogel Product Applications for High-Temperature Thermal Insulation

This paper presents the results of theoretical and experimental studies to determine the optimal thickness of thermal insulation from basalt fiber and aerogel products for pipelines at temperatures of 300 and 600 °C. We carried out a comparison of the key thermophysical characteristics of the claimed heat-insulating materials. We performed a thermal imaging survey of the furnace chimney, insulated with basalt fiber and aerogel, while controlling the temperature of the flue gases by establishing the required ratio of the flow rate of natural gas and oxidizer. The temperature gradient along the thickness of the thermal insulation was obtained using a numerical tool developed in ANSYS. The results show that aerogel surpasses basalt fiber in all key thermophysical characteristics. At the same time, the only barrier to widespread industrial production and use of aerogel in the high-temperature thermal insulation segment is its market cost, which is still several times higher than that of basalt fiber in terms of an equivalent performance
