In Poland, fossil fuels are used to produce electricity and heat. A key aspect of the industrial use of thermal equipment is the emission of carbon dioxide into the atmosphere, which can affect the greenhouse effect leading to global warming. The combustion of gaseous fuels also harms the environment, particularly in terms of NOx emissions. The main aim of the study was to analyze the test results of the innovative burner. The conditions under which NOx concentrations can be reduced were also analyzed. The article presents the results of research on combustion processes in laboratory and operating conditions (hearth systems) in industrial thermal devices. Combustion planes of several categories of diffusion gas burners were studied under laboratory conditions. The technical, energetic and operational parameters of combustion chambers in thermal devices were characterized and analyzed. The influence of the degree of turbulence of the combustion substrates on NOx concentrations in the flue gas was determined. They were looking for a solution that should be used to reduce NOx concentrations, as this could lead to an innovative solution with a positive environmental impact. The discussion part indicates which solutions analyzed in the article are innovative and divides them into process and product innovations. In the diffusion burner tested, an air swirl angle of 60° provides the best environmental results in terms of minimizing NOx emissions. In typical diffusion burners, high substrates discharge velocities (usually up to 60 m/s) are preferred. Higher outflow velocities (e.g., in fast-flame burners) can lead to excessive vibro-acoustic emissions, which are detrimental to the operation and durability of the device. The environmental effects of the presented technology are a very important practical effect. Especially nowadays, when there is a very strong need to reduce the negative impact of production processes on the environment. Innovations leading to lower NOx concentrations can be seen as very important for the business.
