Diesel-fired boiler performance and emissions measurements using a combination of diesel and palm biodiesel

Biodiesel is widely accepted as a fuel that similar to diesel with various advantages. Biodiesel's low-temperature flow qualities are one of its characteristics limits use. The goal this study was see how volumetric blends palm biodiesel and diesel, affected the performance emissions fired vertical coil type, water tube, non IBR boiler. Various were prepared like PB25, PB50, PB75, PB100 test in boiler variation injection pressure. Performance fuels observed 62.73%, 62.45%, 62.36%, 62.32%, respectively, compare pure value all either slightly higher or comparative. maximum efficiency B100 64.98%, which lower than 65.30%. Because has kinematic viscosity, it larger droplet diameter lead poor spray formation thus efficiency. At 11 bar pressure, EGT for 300 °C, 295 308 328 340 respectively. Other blends, exception B25, have fuel. same pressure bar, CO from B50, B75, 0.037%/Vol., 0.0336%/Vol., 0.0326%/Vol., 0.033%/Vol., 0.036%/Vol., PB50 lowest tested, followed by B100. at 0.0605%/Vol., 0.0616%/Vol., 0.060%/Vol., 0.05%/Vol., When compared fuel, 21% higher. highest HC 18 ppm, 16 14 13 12 ppm utilizing reduced around half when using
