Abstract:

 


This
study investigates the particulate matter formation during combustion of olive
residue, almond shell, and Tunçbilek lignite. Selected fuels (olive residue and
Tunçbilek lignite) were also co-fired to evaluate the influence on particulate
matter emission. Olive residue was ground to different size ranges (< 125 µm
and 212–300 µm) to investigate the influence of the particle size and blended
in different ratios of biomass / coal to analyse the interactions between
fuels. Tests were performed in a drop tube furnace at high temperature (1000
ºC), with a high heating rate (~104 ºC/s), and short residence time
(~3 s). Fuel was fed into the furnace at a low mass rate of 10 g/h using a
syringe pump. Particulate matter was collected using a 3-stage stack impactor
and categorized according to the aerodynamic diameters, PM2.5, PM2.5-10, and
PM10. The results obtained included particle burnout, and particulate matter
concentration. Particle burnout was above 95% for all studied fuels.
Particulate matter emission depended greatly on the fuel and the blend. Olive
residue presented the lowest values of PM2.5 (176 mg/g ash in fuel fed)
compared with both almond shell (214 mg/g ash in fuel fed) and Tunçbilek
lignite (286 mg/g ash in fuel fed). PM10 emission was particularly low for
olive residue (~200 mg/g ash in fuel fed), whereas almond shell and Tunçbilek
lignite showed similar values (~400 mg/g ash in fuel fed). Larger biomass particles
resulted in unchanged particulate matter emissions. Co-firing of the olive
residue with the Tunçbilek lignite resulted in lower PM2.5 (as compared to neat
olive); higher PM2.5-10 (as compared to neat lignite); and lower PM10 (as
compared to lignite). Blends of OR-TL in 25-75 ratio showed lower values of
both PM2.5 and PM10 as compared with the 50-50 blends of the same fuels.
