The thick iron keeps the heat which would otherwise be lost and gives back this heat to the room. A fireback thus may increase the efficiency of the fire. Wood fires have low efficiency, and for those that prefer the atmosphere of an open wood fire the fireback helps to minimise this problem.
A split is often made down the length of the grooved piece, so that oxygen can flow freely to the coal/ember. A fire-saw is a method by which a piece of wood is sawed through a notch in a second piece or pieces to generate friction. The tinder may be placed between two slats of wood with the third piece or "saw" drawn over them above the tinder ...
A fireplace insert [1] is a device that can be inserted into an existing masonry or prefabricated wood fireplace. Fireplace inserts can be fuelled by gas, wood, electricity, coal, or wood pallet. Most fireplace inserts are made from cast iron or steel. Fresh air enters through vents below the insert, where it then circulates around the main ...

Any joint made by fastening together pieces with the ends cut at an angle. mitre box. Also spelled miter box. A box used for making mitre joints by having slots to guide a saw at the desired angle for the joint. mitre saw
] Pyrolysis gas has a high percentage of heavy tar fractions, which condense at relatively high temperatures, preventing its direct use in gas burners and internal combustion engines, unlike syngas. The process is used heavily in the chemical industry , for example, to produce ethylene , many forms of carbon , and other chemicals from petroleum ...
Rift sawing is a woodworking process that aims to produce lumber that is less vulnerable to distortion than flat-sawn lumber. Rift-sawing may be done strictly along a log's radials—perpendicular to the annular growth ring orientation or wood grain —or as part of the quarter sawing process.
Rip cuts are commonly made with a table saw, but other types of power saws can also be used, including a radial arm saw, band saw, and hand held circular saw.In sawmills the head saw is the first rip-saw a log goes through, which is sometimes a gang-saw, and then the cants may be resawn using other saws and then edged in an edger and sometimes cut to length by a crosscut saw.
The actual wood volume of a cord may be in the range of 80 to 100 cubic feet (2.3 to 2.8 m 3) as stacked wood takes up more space than a piece of solid wood. The most common firewood piece length is 16 inches (41 cm). [28] The volume of a face cord or a rick [29] depends on the length of the logs that are stacked in a 4 by 8 ft (1.22 by 2.44 m ...
