A stump grinder is a machine designed to remove tree stumps by using a rotating cutting disc that chips away the wood. The machine typically features a cutter wheel with fixed carbide teeth. The cutter wheel's movements are controlled by hydraulic cylinders , which allow it to move laterally and vertically to grind through the stump.
The stump is the base of the trunk and the attached woody roots. Tree stumps and roots are extracted using a hydraulic head on a tracked excavator or with a mechanical head equipped by a special tool for tractors. Stump harvesting is expected to provide an increasing component of the woody material required by the woody biomass power sector in ...
Tree stump, about 37 years after falling. After a tree has been cut and has fallen, the stump or tree stump is usually a small remaining portion of the trunk with the roots still in the ground. Stumps may show the age-defining rings of a tree. The study of these rings is known as dendrochronology. Stump sculpture by German artist Eberhard Bosslet

Wood burning advocates claim [weasel words] that properly harvested wood is carbon-neutral, therefore off-setting the negative impact of by-product particles given off during the burning process. In the context of forest wildfires, wood removed from the forest setting for use as wood fuel can reduce overall emissions by decreasing the quantity ...
Many different sugars are used as the fuel for rocket candy. The most common fuel is typically sucrose, however, glucose and fructose are sometimes used. As an alternative, sorbitol, a sugar alcohol commonly used as a sweetener in food, produces a propellant with a slower burn rate and is less brittle when made into propellant grains. [5]
A thermal lance, thermic lance, oxygen lance, or burning bar is a tool that heats and melts steel in the presence of pressurized oxygen to create very high temperatures for cutting. It consists of a long steel tube packed with alloy steel rods, which serve as fuel; these are sometimes mixed with aluminum rods to increase the heat output.
