З 1961 р. у ХПІ видається збірник наукових праць "Вісник Харківського політехнічного інституту".
Згідно до наказу ректора № 158-1 від 07.05.2001 року "Про упорядкування видання вісника НТУ "ХПІ", збірник був перейменований у Вісник Національного Технічного Університету "ХПІ".
Вісник Національного технічного університету "Харківський політехнічний інститут" включено до переліку спеціалізованих видань ВАК України і виходить по серіях, що відображають наукові напрямки діяльності вчених університету та потенційних здобувачів вчених ступенів та звань.
Зараз налічується 30 діючих тематичних редколегій. Вісник друкує статті як співробітників НТУ "ХПІ", так і статті авторів інших наукових закладів України та зарубіжжя, які представлені у даному розділі.

    Peculiarities of ecologically oriented recreational complexes of Europe
    (Національний технічний університет "Харківський політехнічний інститут", 2024) Levytska, Olena Hryhoriivna
    The demand for safe recreation conditions is growing every day. Therefore, hotels, lodges which acquire ecological characteristics, improving the interiors of the premises, the exterior of the territories, causing green areas and growing organic products, supporting the ideas of resource conservation and remediation of territories. The purpose of this article is to evaluate the most successful tourism eco-projects in Europe, to identify environmental criteria that attract vacationers and improve the quality of the environment, to evaluate the service, natural attraction and creativity of holiday destinations, to make a comparative description of hotels and resorts located in different natural areas. Service, proximity to nature and the satisfaction of visitors with interaction of nature, design of the exterior and interior, the availability of exclusive decor items, and non-standard leisure activities are the three important criteria for choosing a hotel or resort today. These three criteria were studied by the method of manual analysis of visitor reviews. Most often vacationers mention natural beauty, somewhat less often – service, and quite rarely – creativity in the design and organization of recreation. For the first time, the most successfully functioning ecological resorts in Europe are divided into groups by location and natural resources. The requirements for resorts that are popular among the visitors have been formed. The criteria of service, natural advantages and creativity in different groups are compared.

    Comparative assessment of gaseous fuel emission
    (Національний технічний університет "Харківський політехнічний інститут", 2021) Levytska, Olena Hryhoriivna; Voytenko, Yulia Vladimirovna; Orishechok, Anastasiia Oleksiivna
    The work presents estimated comparative assessment of emissions release in combustion products during work of high–power steam boilers with the use of traditional fuel –natural gas and alternative fuels – blast–furnace and coke–oven gases generated in the process of technological cycle at iron and steel and coke–chemical enterprises. Calculation algorithm is shown and formulas for assessment of carbon content in exhaust gases are defined, conclusions on ecological efficiency of gaseous fuels are given. The purpose of the work was to evaluate the emissions of harmful substances generated during the combustion of natural, blast furnace and coke oven gases, justification of the calculation of carbon content of a given chemical composition and determine the optimal environmental impact of analogues of natural gas. The comparative estimation of pollutant emissions into atmospheric air during combustion of natural, coke oven and blast furnace gases revealed: –high sulfur dioxide emissions from combustion of blast furnace and coke oven gases due to the presence of sulfur compounds in the composition of these gases; –relatively high emissions of nitrogen compounds for natural and coke oven gases and relatively low emissions for blast furnace gas; – сarbon emissions are high for all types of fuels which have been considered, most carbon dioxide gets into the air when burning natural gas, least – when burning blast furnace gas; –significantly higher methane emissions are observed during the combustion of natural and coke oven gases, respectively, smaller – for blast–furnace gas combustion; –coke oven and natural gases are characterized by low mercury emissions. Comparative assessment of the calculated values of hazardous substances emissions in the combustion products in the process of combustion of natural, coke–oven and blast–furnace gases shows that even at lower working heat of combustion values the coke–oven and blast–furnace gases can compete with natural gas. For the first time, a comparative characterization of the emissions of harmful substances in the combustion of natural, coke oven and blast furnace gases is presented, and it is shown that the gases used in coke and metallurgical industries, which are used as analogues of natural, are logical to use, but require the installation of treatment systems. The paper defines a formula for calculating the carbon content in natural gas from the Urengoy–Uzhhorod gas pipeline. The provided calculations and the introduction of simplified formulas serve as an example for the calculation of emission factors and emissions in assessing the level of safety of existing equipment and can be used in the development of permit documents of enterprises that carry out emissions of harmful substances to the environment.
