A critical production problem is to ensure reliable ignition of burner devices of complex process equipment, for example, an autothermal reforming reactor, during its start-up. Unsuccessful ignition can lead to the formation of explosive concentrations of a flammable mixture in subsequent elements of the process chain. This, in turn, can provoke uncontrolled exothermic reactions and, as a consequence, emergency situations with potential damage to equipment and personnel. The developed product provides a radical solution to the problem, guaranteeing stable and reliable ignition, – said the responsible executor of the development, an expert of the Scientific and Educational Center "Digital Engineering of the Main Equipment of Chemical-Engineering Systems" of the St. Petersburg Polytechnical School Yuri Aristovich.
The ignition device is a structurally and functionally unified device – a complex technical system in which all components are interconnected and jointly implement the function of igniting the combustible mixture. The device contains a housing, an oxidizer supply pipe and a combustible gas supply pipe, a spark plug, valves of the oxidizer supply pipe and the combustible gas supply pipe, an outlet pipe. The housing contains a cylindrical mixing chamber, the inputs of the oxidizer supply pipe and the combustible gas supply pipe are located in the part of the mixing chamber that is most distant from the outlet pipe.
The oxidizer feed pipe is connected to the housing so as to feed the oxidizer in the tangential direction, and the combustible gas feed pipe is connected so as to feed the combustible gas in the radial direction. The inlet openings of the pipes in the housing are made so as to ensure critical gas outflow. The dimensions of the inlet openings are reasonably selected so that when the back pressure changes, the flow rates of the combustible gas and oxidizer change proportionally, the diameter of the outlet pipe is from 10 to 50% of the diameter of the mixing chamber. The technical result is an increase in the reliability of the device.
The ignition device is designed to operate in a short-pulse mode. This ensures reliable ignition at low thermal loads in a wide range of pressures (from 1 to several tens of atmospheres). The device forms and directs small volumes of flame – fire ellipses of a certain size and at a given speed. Ignition charges ensure reliable ignition of the main burner, minimizing the thermal load on the outflow zone and the ignition device body, which significantly simplifies the reactor design and its startup procedure.
The task of developing an igniter within the established deadlines seemed extremely difficult. Initially, it was assumed that the system would be implemented with a developed cooling infrastructure and multi-component thermal protection, which is due to the extremely high operating temperatures that significantly exceed the parameters of standard devices. The specifics of the reactor excluded the possibility of using serial solutions. Alternative options were considered, including the use of pyrotechnic cartridges, but this approach was recognized as suboptimal in terms of manufacturability and operational safety. As a result, an original, reliable and safe igniter was created that meets all the requirements. The developed device demonstrates high potential for use not only within the framework of this project, but also in other industries that require reliable systems for initiating processes in high temperatures and aggressive environments, added Nikolay Vasiliev, Chief Designer for Remotely Controlled and Transport and Technological Equipment at JSC TsKBM.
Chief designer for the key scientific and technological development area of SPbPU "Systemic Digital Engineering", director of the Advanced Engineering School of SPbPU "Digital Engineering" Alexey Borovkov spoke about the key success factor: "At the beginning of the work, none of the authors of the development could foresee the final result of creating a science-intensive and high-tech product. By combining the knowledge, experience and competencies of scientists, engineers and designers from various fields of knowledge and industries, we managed to form a unique multidisciplinary team and obtain impressive results. Of course, this is a logical result of the application of systemic digital engineering technologies, including the technology of developing digital twins, mathematical and computer modeling of non-stationary nonlinear physical-mechanical and physical-chemical processes of the behavior of a high-tech product.
The development of a complex technical system is based on the effective application of the created multidisciplinary digital model [ 1, 2, 3 ], which is a system of interconnected mathematical and computer models describing combustion kinetics, chemical thermodynamics of free-radical reactions, dynamics of vortex flows at supercritical parameters of substances and non-stationary nonlinear thermomechanics. Numerous digital (virtual) tests and the necessary full-scale tests made it possible to carry out verification [ 1, 2 ] and validation [1, 2] developed models, to raise the level adequacy of models and descriptions of complex processes confirmed the efficiency and reliability of the developed high-tech product.
With the help of approaches, technologies and methods of system digital engineering, the formed innovative scientific and technical groundwork and on the basis of the digital platform for the development and application of digital twins CML-Bench® [ 1, 2 ] our team implemented all stages of creating a finished industrial product in record time: development and design took only 2 months, manufacturing and testing – 3 months. It is fundamentally important to note that traditional approaches are not capable of ensuring such a high speed of implementation of science-intensive and high-tech projects for the development of complex technical systems."
In conclusion, we note that the results of the development of the ignition device have made a significant contribution to the formation of a scientific and technological reserve for the creation digital (virtual) testing ground for burner devices. The development of a digital test site is one of the most important final goals of a large-scale project to develop new generation burner devices for pyrolysis furnaces, implemented within the framework of the key scientific and technological direction (KNTD-1) of the development of SPbPU "Systemic Digital Engineering" within the framework of the "Priority-2030" program.
The project within the framework of KNTN-1 provides for the definition of approaches to mathematical and computer modeling of new burner devices, development matrices requirements, target indicators and resource constraints, creation of a series of computer models of the prototype (primary, refined, detailed, optimized), conducting full-scale tests of a pilot industrial model of a burner device for validations computer model, development of design documentation and implementation into production.
Let us recall that in June 2025, specialists from the Scientific and Educational Center “Digital Engineering of the Main Equipment of Chemical-Engineering Systems” of the SPbPU PISh presented This project and the Center’s expertise in developing burner devices at the Gazprom Neft site, one of the leaders in the oil and gas industry and petrochemical industry in Russia.
