Ash agglomeration and deposition during combustion of poultry litter in a bubbling fluidized-bed combustor

peer-reviewedn this study, we have characterized the ash resulting from fluidized bed combustion of poultry litter as being dominated by a coarse fraction of crystalline ash composed of alkali-Ca-phosphates and a fine fraction of particulate K2SO4 and KCl. Bed agglomeration was found to be coating-induced with two distinct layers present. The inner layer (0.05–0.09 mm thick) was formed due to the reaction of gaseous potassium with the sand (SiO2) surface forming K-silicates with low melting points. Further chemical reaction on the surface of the bed material strengthened the coating forming a molten glassy phase. The outer layer was composed of loosely bound, fine particulate ash originating from the char. Thermodynamic equilibrium calculations showed slag formation in the combustion zone is highly temperature-dependent, with slag formation predicted to increase from 1.8 kg at 600 °C to 7.35 kg at 1000 °C per hour of operation (5.21 kg of ash). Of this slag phase, SiO2 and K2O were the dominant phases, accounting for almost 95%, highlighting the role of K-silicates in initiating bed agglomeration. The remaining 5% was predicted to consist mainly of Al2O3, K2SO4, and Na2O. Deposition downstream in the low-temperature regions was found to occur mostly through the vaporization–condensation mechanism, with equilibrium decreasing significantly with decreasing temperatures. The dominant alkali chloride-containing gas predicted to form in the combustion zone was KCl, which corresponds with the high KCl content in the fine baghouse ash

GENDER DIFFERENCES IN THE HEALTH BENEFITS OF A BICYCLE-PEDESTRIAN TRAIL

We conducted a survey of visitors to a pedestrian and walking trail that circles the city of Carrollton, Georgia. The trail is called the Carrollton GreenBelt, and it is also considered a linear park. We intercepted visitors as they used the trail, approaching them at set places and times over a six-week period, and we repeated this methodology, collecting three waves of data at 9 month intervals between the fall of 2015 and the spring of 2017. Our goals were to learn about how using the trail impacts the health behavior and transportation choices made by the park\u27s visitors. As we began analyzing the first wave of data, we noticed that men visited the park more often and exercised more vigorously on the trail than women did - yet it was women who reported receiving the greatest health benefits from using the trail. We were surprised, because this goes against the common finding that men enjoy better health than women, while women lead longer lives. To understand this puzzle, we also considered the effect of socializing on health. We noticed that people who used the trail with others get more benefit from the park than those who use it alone - and because women use the park with others more than men do, they gain a greater share of the health benefits than men do
