Oak is the most widely used hardwood. (2) Among those many things, the most popular is Gothic and William & Mary furniture and also many contemporary pieces. Oak is also known as a hardwood, and has over 60 species in the U.S. The species can be separated into two different groups in reference to its bark, the red group and the white group. The red is also known as the black oak. If you were to burn oak it should be seasoned for over one full year if you want the best outcome, so that means …show more content…
Pine trees are harvested (cut down) and depending on which mill the logger / harvester is cutting for, the mill goes through a timber buyer who contracts a logging company to go out and harvest the wood. (3) Depending on the mill that the logger is cutting for will provide a strict set of dimensions listed in the contract that they want the logs cut to. Pine logs being cut for the purpose of Lumber for hardware stores such as Lowes, Home Depot etc. will be cut to fill orders such as 1x4, 2x4, 2x6 etc. Pine logs being cut for the purpose of Plywood for the same store will be cut to various lengths such as 17, 26, 35 (1) foot lengths with the butt and the tops of the logs falling within a certain diameter listed in the …show more content…
(5) The process of combustion is when oxygen has a chemical reaction to heat, but the speed of combustion depends on the amount of oxygen available and the amount of heat applied. All the fire needs to burn is heat, fuel, and oxygen known as the fire triangle or fire tetrahedron when you place the chemical chain reaction in the formula. Fuel can come in a solid, liquid, or gas. In combustion, only gasses react. In complete combustion the flame will typically be blue and you will have charring effects left over, but there needs to be enough oxygen present to mix completely with the gasses and the fire will only produce water and carbon dioxide which means there will be no smoke. An example of complete combustion is when you have a natural gas burning stove top. Incomplete combustion is when there aren’t enough oxygen molecules during the chemical reaction and the flame is usually orange or yellow. When incomplete combustion occurs, there will be smoke present and carbon, carbon dioxide, carbon monoxide, and oxygen molecules will be produced by the fire. It is very important when using liquid gas fires to always have a carbon monoxide detector preset. Carbon monoxide is a colorless odorless invisible gas produced from incomplete combustions and it will disguise itself as oxygen and enter your lungs but then is discovered not to be real oxygen and you will suffer respitory
