Budimex works on an innovative power technology

The Consortium includes the representatives of Budimex SA, Institute of Power Engineering – Research Institute and Mostostal Kraków, and it works on an innovative project called SeNeX. The aim of the proposed technology is to ensure the reduction of emissions of harmful substances from the combustion of hard coal in the MCP grate furnaces used in the power sector in Poland.

The new technology will be used by the power sector, in particular heat and combined heat and power plants, and industrial plants, such as sugar factories or chemical plants.

The solution to the problem of reducing emissions is important for both ecological and economic reasons. Failure to meet the emission limits will result in financial penalties or even the order to shut down the heating boiler. As a result, the production capacity of the industrial plant can be reduced with all its consequences.

The project will use patented nozzles installed in the boiler. They ensure a precisely controlled injection of reagents to reduce sulphur dioxide (SO2) and nitrogen oxide (NOx) – within the appropriate temperature range inside the boiler and regardless of its load. The layout and the position of the nozzles will be controlled by an algorithm. The industrial and development research carried out by the consortium partners include the model and operation of the selected boiler and its purpose will be to indicate the optimum place of nozzle installation. The operating parameters will be determined and the project includes the development of the control algorithm for nozzle position and reagent dosing.

As part of SeNex, a special installation was designed, its implementation method and integration with the heating plant infrastructure. The project will end with tests, performance evaluation and technical and economic analysis of the proposed solution.

The project is co-financed by the National Centre for Research and Development within Measure 4.1 of the Smart Growth Operational Programme 2014-2020. The first works on SeNeX technology began in May 2019 and the completion is planned for February 2022.
