Saravanan Balusamy: Swirling fire
Coal power plants are the major sources of CO2 emissions. One way to reduce the pollutant emissions is to burn the coal particles in oxyfuel environment rather than plain air condition. In the oxyfuel environment, N2 in the air is replaced by the CO2 to control the combustion process and that eliminates NOx emissions. The burned product mostly contains CO2, which can be separated and compressed into liquid form for easy transportation. The goal of our project is to investigate the pulverized coal combustion in oxyfuel environment under well defined boundary conditions. We have fabricated an open type swirl stabilized burner and carried out experiments in a controlled environment. The images are showing the coal particles burning in the O2/CO2 environment supported by the pilot methane-air flame, which appears as blue in color. The pilot flame is a swirl stabilized flame anchored on top of the burner and heats the coal particles in order to ignite them. Laser diagnostic techniques have been applied to measure the flow and scalar parameters of coal particle combustion. The photos are taken with Fujifilm FinePix HS10 and no image processing is applied. Our group members: Saravanan Balusamy, Ruigang Zhou, Alexander Schmidt. Principal Investigator: Prof. Simone Hochgreb
