Biogas Clay Brick Kiln Burner

Abstract

Biogas burners were designed in different geometrical for different purpose like for cooking, beking injera and the likes. This biogas burner for clay brick firing is designed for firing clay brick in the clay brick kiln. Biogas clay brick burner was specifically designed to replace firewood, caw dung and other non-renewable energy source used in local and mechanized clay brick manufactures. Because of the arrangement of clay brick in the clay brick kiln, bar types of biogas burner was selected and all components of biogas burner in the biogas burner design is considered.

CFD Simulation of Biogas Fired Clay Brick Kiln

“…Adiabatic flame temperature of biogas was taken as inlet temperature in both fluegas and wall in the combustion box by considering combustion efficiency of boigas. The adiabatic flame temperature is calculated in the section of Combustion of Biogas Beyene et al (2018) which is equals to 2145.8K. By taking combustion efficiency of biogas as 98%, the inlet temperature for fluegas would be 2103K and the adiabatic flame temperature at 35mm from burner plate is taken as inlet wall temperature which is approximated to 1800K.…”

“…In this CFD simulation, bricks are fired by combustion of methane in the biogas combustion box using biogas burner designed in the section by Beyene et al (2018). Tehzeeb et al (2012) used CFD simulation in order to analysis the flow in the Hoffman kiln brick firing furnace.…”
