| HydroX: Burner Optimization for Decarbonization | |
| Program: | SRDA |
| Project leader: | Ing. Falat Ladislav, PhD. |
| Annotation: | The present project is focused on the development of universal burner design modifications for indirect heating by radiation tubes operating in vacuum mode, which is capable of adaptation to the time and technically conditioned decarbonization rate, i.e. gradual increase of the hydrogen content in the gaseous mixture of fossil fuel, which can reflect the production conditions, especially the required heat input and minimize the production of CO and NOx emissions and thermal stress due to different combustion characteristics of the basic combustible gases. The starting point for burner design modifications is a mathematical model of the hydrodynamics of mixing and kinetics of combustion of the CH4-H2 fuel mixture with hydrogen content in defined intervals. The actual design of the structural modifications of the current burners consists in the construction of a variable nozzle at the burner orifice. This is a set of nozzles for the supply of combustion air and fuel. An important part of the design of the nozzle and burner mouth design will be CFD simulations, which will be compared and verified based on measurements on the constructed physical model in the burner-radiation tube-cooling chamber system. The submitted project includes a comprehensive material analysis of the burner materials, welded joints and bends of the radiation tube exposed to thermal and hydrogen exposure to evaluate different types of material degradation (thermal embrittlement, hydrogen damage). The originality lies in the development of versatile burner designs for indirect heating capable of adaptively adapting to combustion conditions while changing the composition of the natural gas and maintaining the heat input. Universal design modifications will thus support the idea of circular economy. The output of the project will be a utility model application, and scientific articles and teaching materials for the design, development and structural modification of burners for indirect heating. |

| Development of advanced lightweight nanostructured steel and its manufacturing-easy heat processing for ultrahigh-strength applications | |
| Program: | SRDA |
| Project leader: | Prof. Ing. Iefremenko Vasyl, DrSc. |
| Annotation: | The project is aimed at the development of novel cost-saving steel for ultrahigh-strength applications (ultimatetensile stress not less than 2000 MPa under acceptable ductility/impact toughness) and the technology of its hotdeformation and heat treatment which can be easily integrated into the production lines present at the metallurgicalplants. The steel will not comprise the expensive alloying elements (Ni, Cr, Co, Mo, V), in contrast, due to using thecheaper elements (such as Mn, Si, and Al which are lighter than Fe) it will acquire the lightweight feature. The mainobjective will be reached through the formation of a multi-phase "smart" structure that can respond to the externalload by TRIP/TWIP effects leading to self-strengthening and stress relaxation. This structure will be developed bymeans of appropriate chemical composition selection and the novel processing route design based on newtechnological approaches and solutions allowing for a reduction of the processing duration, energy consumptionand using conventional "easy-in-operation" equipment. The results of the project will have a direct positive impacton the metallurgical sector as well as on the users of ultrahigh-strength steels (machine-building, constructionsector) which will benefit from the reduction of steel cost and use the production-easy (time-saving) processingtechnology. |

| INNOVATTOOLS – Inovatívne prístupy k zvyšovaniu životnosti a znižovaniu energetickej náročnosti rezných nástrojov pri spracovaní dreva v lesníctve | |
| Innovative approaches to increase the lifetime and reduce the energy consumption of cutting tools in wood processing in forestry | |
| Program: | SRDA |
| Project leader: | RNDr. Džupon Miroslav, PhD. |
| Annotation: | The project will address the issue of the use of methods and procedures for the modification of cutting tools for wood processing in forestry. The result will be an increase in their lifetime and a reduction in emissions and energy consumption of forestry machinery and equipment. The main objects of research will be tools for primary wood processing, modification and processing of forestry biomass for energy purposes, such as splitting and chipping tools, tools for cross-cutting wood, etc. The main task of the project will be the design of procedures and methods for the modification of exposed functional surfaces of the tools. Ensuring a higher quality of functional tool surfaces in the context of reducing friction and eliminating adhesion, provides a prerequisite for reducing the load on machinery equipment and thus reducing emissions and energy consumption in a given production. Analyses will be carried out on the tools – FEM analysis in order to determine the stress-strain state, on the samples analysis of the state of the material in terms of physical properties, microstructure, mechanical properties and resistance to adhesive wear in wood-metal interaction and also abrasive wear. Based on the results of the analyses carried out, innovative surface treatment procedures will be proposed for the exposed functional surfaces to guarantee an increase in their functional lifetime. These will be applied to samples and laboratory tested by relevant test procedures. From the results of the laboratory tests, a selection will be made of the most appropriate non-conventional innovative procedures, which will be applied to the tools and tested on the equipment under forestry operating conditions. In doing so, it will be observed how the modifications in question affect the energy consumption of forestry machinery and equipment. Part of the project solution will be to ensure industrial-legal protection of the original solutions. |
