لە دڕێژەی کار و چالاکییەکانی فاکەڵتییەکەمان مامۆستای بەشی ئەندازیاری کیمیایی بەڕێز " خدیجە رسول میرزا "کاتژمێر(٨)ی ئەمشەو، ڕێکەوتی ٢٠٢١/٣/٢٩، سمینارێک بە شێوەی ئونلاین پێشکەش بە ئامادەبوونی مامۆستایانی بەڕێز کرد.
ناونیشانی سمینار:
Investigation of porosity effects in the emission of pollutants in porous burners
پوختەی سمینار:
Burners are the devices, providing heat to industrial operations such as chemical reactions, extraction of metals, production of ceramic, etc. At a basic level, burners are devices used to mix fuel and air (or oxygen) to achieve controlled combustion to producing heat. Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. One of the strategies for controlling the air pollution is increasing the combustion efficiency for reducing the fuel consumption. So, a burner should control the combustion of fuel for producing the heat.
Porous burners consume low value of fuels for producing the heat. This may be a solution to reduce the production of CO and N𝐎x. Aluminum oxide (A𝐥2 𝐎3), silicon carbide (SiC), and zirconium dioxide (Zr𝐎2) proposed as suitable materials for application. These materials show good thermal shock resistance, mechanical strength, and conductive heat transport. Advantages of porous burner: High radiant output, low NOx and CO emissions, high flame speed, higher power density. High temperature gradient in combustion chamber is the main source of excess emissions such as unburned hydrocarbons (HC), carbon monoxide (CO), soot and suspended particles. Flame temperature decreases by increasing the porosity of the burner. Increasing the porosity of the burner decreases the production of CO, because of uniform temperature. Ceramic foams or fibre structures are advantageous as combustion burner because they have higher porosities .
