Determination of ecological end energy characteristics of modern low-power gas boilers and prospective development technologies of furnace processes

Conducted heat engineering studies of modern low-power boilers (up to 100 kW) of domestic and foreign manufacturers on natural gas close to nominal operating modes. The obtained parameters are generalized. Since in the heating season, most boilers operate at minimum and average power modes, studies of Viessmann Group heating units of the brand "Vitogas 050", with a heat output of 35 kW, equipped with atmospheric burners of various modifications with adjustable power of 20 – 100 % and 65 – 100 % were carried out. In order to search for increasing energy and environmental indicators and approaching the requirements of European standards, studies of gas combustion modes in the AOGV 13 C apparatus under actual operating conditions were carried out. Various sets of automation of the burner device were changed in the apparatus. Analysis of scientific and practical features of low-power boilers and their environmental indicators show that the combustion process is not completely completed and a significant amount of harmful products of incomplete combustion are released into the environment. The main reason for this phenomenon is the relatively low reactivity of natural gaseous hydrocarbons. This shows that existing technological methods do not solve the problem of organizing effective mixture formation between oxygen and combustible fuel. Without fundamental changes in the organization of combustion processes, the development of future heat-generating equipment has no prospects. It is necessary to switch to new principles of hydrocarbon combustion, based on the initiation of thermochemical reactions in combustion processes in combustion processes. The reactivity of mixture formation can be increased by using active ozone radicals, which gave an effective results in pilot testings.
