The use of biodiesel in boilers has great benefits because it reduces exhaust emissions. The purpose of this study is to test the quality of solar and biosolar raw materials as fuel from the boiler, analyze the concentration of pollutant gases (NOx, CO2, SO2) from the combustion of biosolar and diesel oil experimentally. The combustion system in the boiler tends to be simpler than compression ignition as is done with diesel engines. This research was conducted experimentally in a fire tube boiler, with a heat input rate of 60,000 kCal / hour and a pressure of 3 bar using biodiesel made from CPO (crude palm oil) as fuel. The mixture varies at 0, 5, 10, 15, 20 and 25% biodiesel in a mixture with biosolar diesel (B0, B5, B10, B15, B20 and B25). This research was carried out experimentally by testing the exhaust gas emissions generated from the stack gas stack which is expected to produce low exhaust emissions and are environmentally friendly. The results show that the use of biodiesel reduces gas emissions by increasing the value of biodiesel in the mixture. The results showed that the lowest gas emissions were around 4.142% (NOx); 12.50% (SO2) and 7.9% (CO2) contained in a mixture of 25% biodiesel in fuel (B25).

Exhaust Gas Emissions

A swirl stabilized MGT combustor (Turbec T100) was operated with natural gas and was experimentally characterized in two test rigs, a pressurized and optically accessible MGT test rig and an atmospheric combustor test rig. For the detailed characterization of the combustion processes, planar OH-PLIF and simultaneous 3D-stereo PIV measurements were performed in the atmospheric combustor test rig. Flow fields, reaction zones and exhaust gas emissions are reported for a range of pressure scaled MGT load points. Parameter studies on combustor inlet conditions (e.g. air preheating temperature, air and fuel mass flow rates and fuel split) were conducted in the atmospheric combustor test rig. From the parameters studies the fuel split between the pilot and the main stage and the air preheating temperature were found to have the biggest impact on the flame shape, flame stabilization and exhaust gas emissions. The measurements of the ATM test rig are compared with measurements of the pressurized MGT test rig with and without an optically accessible combustion chamber. Opened and closed conical flame and flow pattern were found in both test rigs. Reasons for the two flame and flow pattern are supposed to be the interaction of pilot stage combustion and flow field and the interaction of the dilution air with the combustion and the flow field. The results are discussed and compared with repect to a transferability of combustion characteristics from the ATM test rig to the MGT test rigs.
