Abstract

One of the coal-fired air emissions in boilers is NOx, which has a significant impact on the environment and could cause acid rain, ozone formation, visual impairment and health problems in humans. There are several technologies to reduce and control the formation of NOx emissions, which one of these technologies is the use of over-fire air (OFA). In this research will observe the effect of overfire air (OFA) usage and analyze by numerical 3D modeling method using computational fluid dynamics (CFD) in Paiton 9 power plant boiler and analyzed for 5 (five) OFA damper opening variations, i.e 0%, 25%, 50 %, 75% and 100%. This research will analyze several factors that have significant influence on NOx emission formation, that are: the temperature distribution of the boiler during the combustion process, the distribution of nitrogen oxide (NO) and carbon dioxide (CO2), direction of flue gas flow and trajectory of coal particles and residence time indicating the length of time of burning. The results showed that the lower the flame temperature, the smaller the formation of NOx; the smaller the oxygen content in the combustion process, the smaller the formation of NOx; the shorter the residence time of combustion products in the high temperature zone the smaller the formation of NOx, and the smaller the nitrogen content in coal, the smaller the formation of NOx.

Abstract

In this study, the effects of using gasoline (E0) and gasoline-ethanol blends E70 on engine performance and exhaust emissions have been experimentally investigated. The investigation was conducted on a single-cylinder, four-stroke, spark ignition engine. The experiments were performed by varying the compression ratio and duration injection (100%, 125%, 150%, 175% and 200%) at a speed of 2000 up to 8000 rpm at full open throttle. The experimental results showed that blending gasoline with ethanol slightly increased the torque and decreased carbon monoxide (CO) and hydrocarbon (HC) emissions. It was also found that blending with ethanol allows increasing the compression ratio without knock occurrence

Abstract

Subtitution of the fuel type in the gasoline engine will change the setting The engine parameters as well as modify it to minimize engine performance degradation And increased exhaust emissions. Utilization of ethanol (85% vol.) - gasoline (15% vol.) The combination (E-85) for the gasoline engine requires some machine modifications and setting parameters due to differences in properties and characters between ethanol and gasoline. This study aims to test the effect of ignition timing and compression ratio on the performance of the engine and emission gas emissions. Ignition time varies between 16-24 Before Top Dead Center (BTDC) d. While the compression ratio variation consists of 11 (standart); 12, 12.5 and 13: 1. It was found that advancing the ignition time range 16o-24o BDTC with 13: 1 compression ratio can increase the performance of torque, bmep, and thermal efficiency respectively 7.94%, 5, 82% and 1.6% respectively, and a decrease of emissions of co and hc respectively 56.6% and 0.6% when compared with the performance of standard gasoline-fueled engines (E0).

Abstract

The combustion process in dual fuel diesel engines occurs sequentially starting with premix burning. The premix burning starts with the ignition delay process. The presence of CNG causes the ignition delay process to become longer, thereby reducing engine performance and increasing emissions on dual fuel diesel engines. This study uses diesel engine type Diamond DI 800 with dual fuel indirect injection model system. The method used a variation of diesel pilot injection timing 110 CA, 130 CA, 150 CA, 170 and 190 CA BTDC. Testing is done with a constant engine speed of 1500 rpm and loading 500 to 3000 watts with 500-watt intervals. The results show that by advancing the diesel pilot injection timing where brake horsepower and the average effective pressure between single fuel and dual fuel is not too far as the current and voltage changes generated by the generator are not too small. While optimal thermal efficiency increased by 4.11%, while CO and HC emissions decreased respectively by 10.85%  and 8.28% at occurred at the pilot injection timing 170 CA BTDC but still under the single fuel engine.
