![]() Humburg had even heard reports of a sunflower dust cloud seeming to explode. Meanwhile, sensors deployed on a combine had recorded temperatures as high as 800 degrees on exhaust components when the combine was well loaded, well above the ignition point for sunflower pith dust. In ignition tests, sunflower pith dust sitting on a hot plate rose in temperature when the plate was set as low as 500 degrees F, a much lower temperature point than ground-up corn stover or soybean material. It’s all primed with air and ready to burn,” Humburg says. They're just big pockets of air and a little bit of material. “If you look at those particles apart underneath the microscope, they look like Swiss cheese. In their lab studies, Humburg’s SDSU research team discovered that sunflower pith is ground up as it moves through the threshing system, creating a cloud of friable dust that hangs in the air and clings to all parts of the combine and engine. But what was it about sunflower that made it so volatile as compared to other crops in the first place? That confirmed Humburg’s suspicion that a hot exhaust system was a likely culprit in ignition. The dragthing magazine trial#Humburg quickly discovered that sunflower growers had already realized through trial and error that if they went too fast, fires would start, even within minutes of a minor increase in engine load. have to start harvest with the idea, ‘I’ve got two weeks of this, riding the front edge of the seat smelling air, waiting for the next fire to start,’ ” Humburg says. “If you can imagine the stress of driving your car down the road and knowing that at any moment it’s going to catch fire? Well, you wouldn't like to start a long trip under that circumstance. Sunflower, Humburg says, had become the “poster child for the concept of a fire in a combine.” Growers reported stopping multiple times a day to extinguish smolders in their hopper, usually with a few squirts from a water bottle. Humburg is an industry expert in what causes combine fires in the first place, especially in sunflower, expertise he gained while leading an SDSU research project funded by the South Dakota Oilseeds Council. Pfeiffer purchased “FireStop” kits from Harvest Fire, a company started by Dan Humburg, a retired South Dakota State University (SDSU) agricultural engineer professor. But the other combine was plagued with fires all year long,” Pfeiffer says. “We bought two (kits) and never had a fire in those machines. He decided to give them a try on two of his three combines. Afterwards, through word of mouth, he heard about an after-market add-on kit reputed to prevent the problem. Then Pfeiffer had a neighbor with a combine fire that went out of control. He was so frustrated with the problem he ended up reducing his sunflower acreage partly because “we were just having so much damn trouble with fires, it was a headache.” None of these successful” Pfeiffer recalls. Supports indefinite number of docks and subdocks divided into categories.South Dakota farmer Steve Pfeiffer had used all the old tricks to prevent combine fires during sunflower harvest. The standard dock bundled with AmigaOS 3.9, 4.0 and newver versions. Proprietary (elder versions of it are freeware) Original 68000 version of it is available on Aminet, or in AmiKit preinstalled environment for WinUAE. The dragthing magazine free#Īmistart for Intel based machines is bundled free into AROS. Highly customizable dock-like application. Uses the Akamaru physics engine to render complex interactions. It comes in both 32- and 64-bit versions.Ī lightweight panel replacement written for GTK desktop environments (Gnome, XFCE, Openbox, ect.) It is not very customizeable but supports subdocks. The dragthing magazine windows#Proprietary dock for Windows offered in both freeware and shareware form.Ĭircledock is for Windows machines and takes the form of a circle on the desktop. Its set to be the default in the next Elementary OS release. Enric Naval ( talk) 20:06, 21 August 2011 (UTC) Reply Dock applicationĪ lightweight branch of docky written in vala.
