Determination of flue gas emission values of cotton and sesame stalk briquettes

Abstract

In this study, flue gas emission values of cotton and sesame stalk briquettes which were produced in a conical type briquetting machine were aimed to determine. In order to determine flue gas emission values, the briquettes were burned in a traditional bucket type stove used for household heating. In the study, flue gas emissions ^uch as CO, C02, S02, NOx, H2S and 02, flue gas temperature and combustion efficiency were measured by means of flue gas analyzer. At the end of this study, when the combustion process had a steady-state condition, the flue gas emission values measured during burning of the briquettes were found to be very low. When the combustion process had a steady-state condition, the lowest CO emissions were 57 ppm and 160 ppm, average NOx emissions were 196 ppm and 146 ppm, H2S emissions were 37 ppm and 27 ppm, C02 emissions were 7.92% and 7.41% and 02 emissions were 12.81% and 13.33% for cotton and sesame stalk briquettes, respectively. During the combustion process, cotton and sesame stalk briquettes had no S02 emission. During the steady-state condition, the average flue gas temperature and combustion efficiency for cotton and sesame stalk briquettes were 400 °C and 403 °C, 70% and 69%, respectively.
