In this article results of an experimental study the gasification process of coal in a NOx - Suppressed and Smokeless stove under different ventilation conditions is presented. NO and CO emissions of the stove were measured during air supply three different sections which are below the grate
to the gasification region and to the pyrolysis region. On basis of the experimental data it was investigated how operating parameters such as gas composition
temperature and gas residence time will affect NO emissions.
