Preliminary Tests in order to assess the Pollutant Emissions of a New Designed Lignite Burner

One of the objectives of our Research Project [1] is the development and implementation of advanced combustion technology, innovative and original with low emissions, for indigenous coal to be combusted in industrial energy boilers in Romania. By the high level of complexity for the scientific and technical activities which are developed during the research, it will be developed a clean-burning coal technology with application to steam generators of type 525 t/h. The past status of the research is represented by the design, tests on wind tunnel and modeling [2] of a new experimental model burner based on the staggered combustion technique, in order to decrease the NO x emissions. The present research stage, that will be further presented, is focused on the design, manufacturing, mounting and testing of a pilot prototype burner. The tests were performed in a 2 MW th pilot furnace installed at University Politehnica of Bucharest and the results were compared with the tests achieved on the site of CHP Isalniţa at the start of the project.
